You might think heat exchangers would always need to be made of metals, which quickly absorb and conduct heat—and many of them are. But heat exchangers can also be made of ceramics, composites (based on either metals or ceramics), and even plastics (polyme ...

Saving energy is a huge and costly problem for factory bosses and it’s one reason they often install devices called heat exchangers to salvage as much heat as possible from waste gases. Heat exchangers have lots of other familiar uses too. Engines in ...

You can see heat exchangers in all kinds of places, usually working to heat or cool buildings or helping engines and machines to work more efficiently. Refrigerators and air-conditioners, for example, use heat exchangers in the opposite way from central he ...

Suppose you have a gas central heating furnace (boiler) that heats hot-water radiators in various rooms in your home. It works by burning natural gas, making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. As ...

Hydrotest for Pipe Fittings Hydrostatic test or hydro test is not required for pipe fittings unless specifically requested by the purchaser. Code mandate that fittings shall be able to withstand under pressure required by applicable Piping Code. But all ma ...

Low alloy steel refers to alloy steel with total alloying elements less than 5%. Compared with carbon steel, low alloy steel is intended to add one or several alloy elements to the steel in order to improve the performance of the steel on the basis of carb ...

Carbon steel is used for normal pressure temperature applications. Alloy steel is used for high-pressure temperature applications. Stainless steel is used for corrosive applications. And nickel steel is used for a low-temperature application. Here I will s ...
