Characteristics of carbon steel pipe fitting tee

　　Carbon steel pipe fitting tee is a steel elbow formed by hot pressing or forging. Its connection form is to directly butt weld the pipe fitting tee with the steel pipe. The main manufacturing standards of butt welded tee are generally GB / t12459, GB / T13401 and ASME B16 9、SH3408、SH3409、HG/T21635、HG/T21631、SY/T0510。

　　Carbon steel pipe fitting tees generally include equal diameter pipe fitting tees, reducing pipe fitting tees, etc. the materials include carbon steel, alloy steel and stainless steel.

　　When the chromium content in the steel reaches about 1.2%, a thin oxide film (self passivation film) is formed on the steel surface by the action of chromium and oxygen in the corrosive medium. The seamless pipe fitting tee can prevent the further corrosion of the steel matrix In addition to chromium, the commonly used alloy elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements for the structure and properties of concentric reducer for various purposes Certain production and processing technology is adopted in the production of straight pipe fitting tee concentric reducer to ensure good function and performance in production and processing
