Furnace - Wikipedia

A furnace, referred to as a heater or boiler in British English, is a heating unit used to heat up an entire building.Furnaces are mostly used as a major component of a central heating system.The name derives from Latin word fornax, which means oven.Furnaces are permanently installed to provide heat to an interior space through intermediary fluid movement, which may be air, steam, or hot water.

The coating applied at a coating mill typically leaves the ends of the pipe clean, so as not to interfere with welding. Finally, the entire coating of the pipe is inspected to ensure that it is free from defects. Once the pipe is welded, bent, coated, and inspected it can be lowered into the previously-dug trenches.
