Dirty Furnace Filters Can Be Deadly

What do you assume is the result if you neglect to keep your furnace filter clean? Do you think that your furnace will be able to run forever without problems using the same dirty filter year after year? What do you think will happen when your furnace filter becomes over saturated by dirt, pet hair, allergens and dust? You are looking at more than the fan simply refusing to run properly. A dirty furnace filter can be deadly, make you sick or worse, causing your home to go up in flames.

When either your furnace or air conditioning unit are not being maintained properly every six months or every year, dirt, dust and other debris can build up inside causing serious problems in the long run. Not only will you be paying more for heating if your heating unit has to struggle harder to heat the same amount of space but also run the risk of some pretty serious dangers are also involved with not properly responding to a dirty furnace filter. When your furnace and the motor in your air conditioner become clogged by dirt and debris, that air is what will be circulating through your home, rather than the clean, fresh air that you once enjoyed. Your family will be breathing in all these toxins that otherwise would have been sucked out of the air by a clean or new furnace filter. If you continue to breathe this bad air, there is the possibility you will become sick. So if your family is sick and the cause cannot be found, it might be time to replace your furnace filters and to restore the clear air in your home. Learn more about furnace filters at

After a few years worth of furnace filter neglect serious things can possibly happen. Your furnace may simply break down and you will be lucky if you could find a cheap replacement part. If your heat exchanger becomes warped or cracked from the unbearable heat build up within your furnace, noxious carbon monoxide fumes may leak into your home, not only making you sick but also potentially killing you and your entire family. Can you imagine all of this, simply because you could not be bothered to maintain your furnace filter?

Faulty furnaces have also been known to cause fires, all because the furnace filter wasn't clean, and air couldn't circulate properly through the furnace and throughout your home. Clean up after a fire is incredibly expensive, and there is no telling what damage you may in the process. What if your entire house goes up in flames? What is a pet, or a family member is trapped inside when it happens? Hopefully now changing out your furnace filters or buying filters that are permanent and only need to be cleaned seems like less of a trivial matter. You can save yourself a lot of stress, a lot of health problems and a whole lot of financial burden simply by keeping your furnace filters clean, or replacing them often. If there is any doubt, you can always contact a contractor who can check your furnace and clean your filters if need be. Get more information on how to keep your furnace filters clean by checking out

With so many reasons to keep up on your furnace maintenance, and no known reasons for why not to, you should take the next few moments to check out the state of your furnace filter to make sure that air is circulating properly through your home, that your heat exchanger is still in one healthy, solid piece, and that there is no risk or danger present that you could easily have avoided.

Steel pipes and usage

As a business's man, and being a steel pipe supplier, I'm very interested in steel, and aware people about the steel advantages and disadvantages is like my hobby now. Now I'm into a new topic called steel pipes

Stainless steels are alloys that are made up of iron and generally contain around Other than that we also use only very high-quality coating material which results in getting an exceptional end finish. I hope this would have generated some curiosity in your mind and when you see a pipe you would think about it in another perspective.
Stainless steels are alloys that are made up of iron and generally contain around Brearley was trying to make a combination of various alloys for gun barrel steels, and he noticed that samples that were cut from one of these trial heats did not rust and were, in fact, difficult to etch. Various types or grades of Stainless steel are available as per different needs.

Steel rebar is formed from mild steel, and is given ribs for better frictional adhesion to the concrete. The Rebar is an iron rod , a weldable plain reinforcing steel bar, and can be used as well for steel meshes.

Why Steel Piston Rings?

Some of you may be wondering what the difference is between cast iron compression rings and carbon steel compression rings. The advantages are pretty clear – steel rings are 35% stronger, 30% lighter and have double the resistance to side wear.

You might ask – why does it matter if the top ring is lighter? A lighter ring actually has higher RPM potential meaning your engine will attain optimum speed and performance…and your compression rings will do all this while tolerating the abuse of the current high output engines.

Since the steel is 35% stronger than cast iron, we can achieve the same ring tension with 35% less weight. That weight savings is made by reducing the radial wall thickness of the steel ring.

The net result is a ring that's lighter, so it has a higher effective RPM potential, stronger – so that it weathers the abuse of today's high output engines better, and actually seals better because the reduced radial wall allows it to conform to the cylinder wall better.

Having said all that, there's some additional explanation needed when it comes to back clearance – that area behind the ring which is calculated by subtracting the ring radial wall width from the root depth of the ring groove in the piston. For example; if I have a ring radial wall of .170" and a groove depth of .195" then my back clearance is .025".

Reducing the radial wall of the replacement carbon steel rings does increase the back clearance because they are going into piston grooves designed for the thicker radial wall of the cast iron rings.

It's been a well-accepted piston ring engineering design criteria, that for optimum performance, ring back clearance should be minimized. This comes from the fact that the top compression ring needs the pressure from the combustion gases to get in behind the ring and push out on the ring to maintain proper seal on the high pressure, or combustion stroke. The logic was that the smaller the area created by the back clearance, the quicker that pressure would build to push out on the ring, and the quicker the ring would react to its sealing requirements job. That logic is all good but what about the reality of the concept?


Since both components in this equation – pistons and the rings, our MAHLE piston ring R&D lab did some testing in conjunction with one of our OE customers to see if engine testing could tell us what the right amount of back clearance should be. What the lab folks found surprised most all of us! The engine wasn't nearly as sensitive to ring back clearance as it was to ring side clearance.

The reason was the gases have to get past the top side of the ring in order to get around to the back of the ring to push out on it. When we tightened up the side clearance to less than .001″, the ring went unstable even at normal operating RPMs. Blow by, which is gas leaking past the face of the ring, increased dramatically.

Changing the back clearance didn't show us anything, negatively or positively either direction. We realized it was all about having enough side clearance to let the gases flow back to the back of the ring not how much back clearance we had!

We came to the realization that in any cylinder, you have hundreds of CC's of gases available to fill that relatively small volume behind the ring (0.4 cc's), Those gases are at a very high pressure, several hundred, or even thousand PSI, so they will fill the small space behind the ring very quickly if you give them enough room, a.k.a. side clearance, to get there.

Most OE and aftermarket side clearance specs are in the .0015″ – .0025″ range. For our regular, non-racing, customers; changing from a cast iron top ring to a steel top ring won't cause any adverse effect at all from the increased back clearance because the side clearance is adequate to allow the gas movement. Remember, we have hundreds of cc's of gas to fill the very small amount of space change.

The performance engine builders are a different story, but they take care of the issue with custom groove specs. The MAHLE Original performance ring catalog supplies radial wall specifications for every ring for just that reason. Many of the true high performance engine builders specify ring grooves with less than .001″ side clearance, but they add gas ports, small channels drilled in the piston, either from the top or side of the piston, to give a direct path for those combustion gasses to get directly to the back side of the ring. The engine doesn't care how the gases get back behind the ring, it only cares that it does, and in enough volume and pressure to do the job.

In summary, you can replace cast iron top rings with carbon steel, get all the benefits we've talked about in this bulletin, and rest assured we've done our homework on the engineering side!

How to Install Your Own Furnace - 13 Easy Steps

I have broken down the process into 13 easy steps. Will you learn everything I know in this article? Of course not. I have written most of my tips and tricks down in " The Ultimate Furnace Installation Guide " thats available here Click Here for the Guide

This article will help you do is decide weather you can or should install your own furnace. To be honest  most people can install their own furnace, If you have the  tools listed below at home, and know how to use them you can install your own furnace.

What if you do not have marginal handyman skills?

Dont worry I have you covered - My guide "Click here for the guide"  Shows not only what goes into installing your own furnace, BUT it also teaches you how to hire a subcontractor and still save thousands on a new furnace. The Guide give you  the knowledge of how much it should cost to install a furnace verses hiring a contractor blindly without knowing anything about furnace installs. Puts you on an even playing field so to speak.

Step 1. Tool list. Nothing is more frustrating than getting started on a furnace installation job only to find you are missing some of the tools needed to accomplish the job. Most of you already have most of the basic tools you will need. So Heres the list of tools needed.

That should just about do it. You will find you need an odd out tool here and there but this is the general list

Step 2. Assessing your home. You are going to need to understand how your home is made and insulated. Do you have new or old windows and doors? Is there any air infiltrating your home via dryer vents, window fans, etc? Do you have a basement? Or is your home on a concrete slab? You will need to know this in order to install the correct equipment in your home.

Step 3. Assessing the Heating/Cooling system and ductwork. This is the most important step. Why? The answer might surprise you, In fact  It might even surprise some HVAC contractors.

The equipment must be sized right. Hands down. No exceptions. You might be thinking "Doesn't the rule 'the bigger the better' apply here?" No. Let me rephrase that: Heck no! And here's why.

The same principle applies with a furnace. It must be sized properly. To help you out with choosing the right equipment to install, you will need what is called a Heating and Cooling Load Calculator.  As a side note, I have included a free one at . When you land on the home page there is a column on the right hand side of the page, one of the categories says heat cool calculator click on it and it will take you to the calculator.

Step 4. Materials list - Ductwork. It is wise to keep a running list of materials you will need when you go to the store. Perhaps the size of the return needs to be bigger. You no doubt will have to attach the old ductwork to the new furnace. The installation instructions that come with the furnace will tell you the sizes you need for a proper installation. All part of Step 3

Step 5. Materials list - Electrical. As you assess your home as part of step 3, you will be able to determine what your new electrical needs will be. Make a detailed list. Keep in mind that all new furnaces need a ground wire. If you do not have a ground wire on your old power supply, you will have to install one.

Step 6. Materials list - Gas line. Also to be determined in step 3. Hopefully by now you see the wisdom of following this process step by step. Making these lists before you start the installation will help you in the long run. With all of the needed materials on hand, as well as a plan of action, you won't find yourself on the third day of the install, minus 10 degrees, and having to run to 15 different stores.

Step 7. Yet another Materials List - Miscellaneous. The materials on this list are dependent on the type of furnace you have, or will purchase. Ex: an 80% efficient furnace will require different flue pipe materials than a 90% efficient furnace.

Step 8. Finding local suppliers to work with. This might be your biggest hurdle. In the past, you were kinda strapped into your local area suppliers. Nowadays you have the internet. Use it to your advantage. Doing a google search with the words "furnace goodman" will bring up a surprising amount of information. Always make sure to ask about the warranty. Keep in mind here that buying your own furnace saves you thousands of dollars - even if you end up hiring a contractor to install it for you!

Step 9. Remove power and fuel supply from your existing equipment. Yeah I know, but some folks start ripping things apart, and completely forget this step. It's a reminder.

Step 10. Secure your existing ductwork into place. Why? There is nothing more heartbreaking than starting to remove a furnace, only to have the existing ductwork fall to the ground at your feet. Not only does this add another day to your job, but also new 4 letter words to your vocabulary. Hence, Step 10. Secure the existing ductwork with cleats and screws.

Step 11. Removing the old equipment. Now that you have turned off all power to the furnace, and have secured your ductwork, you are ready to start removing the old equipment. Once removed, set it off to the side so that you have plenty of working space.

Step 12. Putting it all back together. This section is broken up into 6 sub-sections.

Step 13. Starting up your equipment. Usually the instructions from the manufacturer will tell you exactly how they would like the new furnace started and tested. Follow their instructions as closely as possible.

There you have it. Twenty years of experience wrapped up in 13 easy steps. If you are thinking of installing your own furnace, I hope this helps you out.

Caster effect?

The high temperature molten steel continuously cast into the production process has a certain shape and a certain cross-sectional dimensions called slab continuous casting.
The equipment needed to complete this process called continuous casting equipment. Pouring steel equipment, continuous casting machine body of the device, the cutting area of ​​the device, hydraulic integration dummy bar collection and delivery device constitutes the core part of the continuous casting equipment, casting machine called habits.

Caster can be classified in several forms. In terms of the structure shape it can be divided into vertical continuous casting machine casting machine, vertical bending caster with a straight segment curved continuous casting machine, arc continuous casting machine, multi-radius oval horizontal continuous casting and continuous casting machine machine. With the development of continuous casting technology, has launched a caster wheel, especially on thin slab caster.
If you follow the caster cast sectional size and shape to distinguish, it can be divided into slab continuous casting machine casting machine, billet caster, bloom caster, the round billet caster, profiled section caster and a thin slab caster. In billet caster also includes a rectangular billet continuous casting machine, usually casting section or equivalent cross-sectional area larger than 200 × 200mm billet called bloom, section or equivalent cross-sectional area less than 160 × 160mm billet slab of petit , thickness ratio greater than 3 rectangular billet called slabs.
If the slab continuous casting machine according to the number of streams in a common casting ladle can be distinguished, it can be divided into single-stream, or double-strand caster.

When breaking the traditional concepts to advanced digital technology to replace the traditional control thought, not only showed the ability to achieve superb technology, but because of the nature of changes in the structure, so that its implementation of traditional systems can not be achieved without the need for complex system designs, parameter setting and adjustment repeatedly, but not because of long-running performance change occurs,

Casting machine from a digital level control, digital line width adjustment (slab), a digital non-sinusoidal vibration, the number two cold water control, digital online soft reduction, continuous casting machine in the process of digitizing all, simple design, high level of technology , low cost, low risk investment advantages you will appreciate sincere.

Hydraulic vibration control system through the six million consecutive vibration test, the test results fully in line with actual production data needs, and equipment intact. Since Bo Billion US adopts the international advanced digital hydraulic cylinder seal structure design, which not only does not have any leaks, seal life is also greatly improved, making the system operating costs far lower than the mechanical vibration system. Mold wall motion solidified shell friction is considered to be torn further solidified shell casting speed limit fundamental factors. The presence of a liquid slag film between the initial shell and the mold wall friction here is viscous friction, ie the friction force is proportional to the relative velocity, the viscosity of the slag film and inversely proportional to the thickness of the slag film. Thus during mold oscillation positive slippage of the friction and tensile stresses on the solidified shell due to large initial shell may crack, for the development of non-sinusoidal vibration technology to reduce this friction. Theory and simulation results show that properly selected non-sinusoidal oscillation parameters (skewness) can reduce friction by 50% to 60%. Billion US Bo technology will transform a simple ordinary caster achieve 400 hydraulic vibration, deflection rate of 50%, and the line can be casting machine adjusted. Is to achieve high quality, high yield caster adapt new technologies.
