Almost all steam boilers are constructed of carbon steel, which rusts if exposed to oxygen and moisture The following steps will minimize this problem. (Please observe "shock & burn warnings."): The boiler's blowdown valve must be safely piped in accordance with state and local codes. Ensure that safe discharge is provided for 100 PSIG and 338 degrees F. Turn the boiler off and allow the pressure to drop to 5 psig. Open the blowdown valve for ten seconds, then close.

Yes. We have been overhauling steel brakes since 1984. We were also one of the first to overhaul carbon brakes for several major airlines. See similar questions...

We make Surgical Blades in both Carbon Steel and Stainless Steel. The chemical compositions are given below :- See similar questions...

Carbon Monoxide (CO) is a toxic colorless, odorless, and tasteless gas. It is produced as a product of incomplete combustion of fuels. See similar questions...

Carbon is an extremely porous material that attracts and holds a wide range of harmful contaminants. Activated carbon is carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules. See similar questions...

Our Carpenter Technology 465 alloy can reach HRC 60. By comparison, carbon steel can reach HRC 62. The difference is about 3%. See similar questions...

Usually less than twenty autoclave cycles. Beyond this the chrome plating will begin to flake off and pitting of the surface will begin-with ferrous contamination of the process beginning. See similar questions...

Charpy Impact Test at Minus 4deg F for set of 3 specimens (including Machining charges) = US $ 30 per set We will need 3 specimens of about 15 x 15 x 75mm. please inform us size ( dia / thickness) of your material so that we can guide you how to take out the sample. See similar questions...

We would need samples from both good and affected portions of the tubes with a minimum of 2 feet in length. Also take care that these tubes are sent without cleaning because we need to analyze Corrosion products deposited on these tubes. If possible you may send additional packet of corrosion products that you may have collected from various tubes also. Please also send complete details of layout of tubes, history of failures and also samples of soil where these tubes are laid. See similar questions...

Only the structural components, such as the framing in the walls and the roof trusses. There are floor systems available for homes with a basement or for those built off the ground. See similar questions...

Steel signs (usually 18 gauge or thinner, even if powder coated or painted with epoxy paint) ALWAYS RUST (especially around the holes and on the edges). Although some companies apply reflective sheeting, most steel signs are painted and are therefore NOT REFLECTIVE. Aluminum does not become brittle and NEVER CRACKS, RUSTS or becomes BRITTLE and is the industry choice for outdoor signs. See similar questions...

Carbon monoxide monitors are useful, though I would not use them as a substitute for preventive actions listed above. They have been a problem due to the tendency of them to go off on bad smog days. The standard for these is just now changing (October 1995) to prevent this. Carbon monoxide monitors operate cumulatively; if they go off you don't know if you are being exposed to a long-term, moderate, non-lethal level or a situation immediately dangerous to life.

The effects are "insidious", that is, the exposure to even small concentration for the duration of a flight may cause reduced performance. See similar questions...

In addition to removing pollutants such as mercury and sulfur, the gasification process allows carbon dioxide (CO2), the leading global warming agent, to be removed with little difficulty from the waste stream. Once separated, the CO2 can be stored permanently underground, buried deep in the earth and stored much like it was stored as coal. This is known as "carbon capture and sequestration" and is strongly supported by leading environmental scientists and global warming experts. See similar questions...

No. Activated carbon filters are usually rated by the size of particles they are able to remove, measured in microns, and generally range from 20 microns (least effective) down to 0.5 microns (most effective). The two most important factors affecting the efficiency of activated carbon filtration are the amount of activated carbon in the unit and the amount of time the contaminant spends in contact with it. The more carbon the better. Particle size also affects contaminant removal rates. See similar questions...

Keeping your carbon monoxide detector in good working order with fresh batteries is very important these days. I can't tell you how many times we have responded to a carbon monoxide detector going off only to find the batteries dead. But, if you hear your detector going off, call the fire department and get out of the house. It's better to be a bit embarrassed then dead. They will determine the source and contact the appropriate people to correct the situation. See similar questions...
