Carbon steel pipe fittings

DataTime:[2016-5-15]

Carbon steel pipe fittings, as the name implies, are made of an alloy of carbon and steel. It is forged or cast in a way that there are no seams to weaken the pipe. You must use fittings such as a variety of flanges or butt weld fittings where necessary. These fittings must also be made of carbon steel.

• Small Pipe Fittings
Carbon steel pipe that has an interior diameter of less than 2 1/2 inches is usually threaded and joined with a carbon steel union of the same size with the same thread configuration. You will also find other carbon steel fittings such as threaded elbows, both at 45 degrees and 90 degrees. Caps are available if you need to shut off a line. Flangesand double release unions can help in awkward places in gas lines. There are also threaded reductions, such as 2 inch to 1 1/2 inch, or 1 inch to 3/4 inch, made of carbon steel.

• Fittings for Large Pipe
Large industrial carbon steel usually has welded unions. One of the exceptions is when the pipe has some type of liner to help prevent corrosion. These liners are usually made of plastic or fiberglass products and can be damaged by the heat of welding. Large carbon steel flanges are available for applications with lined pipe. They also use carbon steel nuts and bolts which can be up to 1 inch in diameter. While these are more expensive to install than a simple weld, they radically reduce corrosion at joins.

• Specialty Fittings
You can buy T joins, both with threads, as well as flanges in carbon steel. These, as well as most other fittings, come in a variety of carbon steel alloys. Lap joins and slip on joins are also available for carbon steel pipe up to 4 inches in diameter. These fittings are used on carbon steel pipe used for everything from household gas lines to the transportation of toxic liquids in an industrial setting.
