Carbon steel tee is generally used for regulating valve installation, using exhaust clean.Concentric reducer tube is beneficial to fluid flow and has little interference to fluid flow state when reducing diameter.
Seamless tee so gas and vertically flowing liquid pipes are reduced in diameter using concentric reducers.Because one side of the eccentric reducing pipe is flat, it is convenient for exhaust or drainage, and convenient for driving and maintenance. Therefore, the liquid pipe installed horizontally is usually eccentric reducing pipe.
Reducing pipe is also called size head, the two ends of the pipe mouth diameter is different, used to connect different diameter pipe or flange for reducing diameter.The two ends of the concentric reducing pipe mouth, the center of the center on the same axis, when reducing diameter, calculate the position of the pipe with the axis, the position of the pipe is unchanged, generally used for gas or vertical liquid pipe diameter.Eccentric reducing pipe at both ends of the pipe mouth circumferential cut, generally used for horizontal liquid pipelines.
Butt-welding tee is a steel elbow formed by hot pressing or forging. Its connection form is directly butt-welding tee with steel pipe. The main manufacturing standards of butt-welding tee are GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.
Butt welding tee generally has equal diameter tee, reducing tee and so on, the material has carbon steel, alloy steel and stainless steel.
Carbon steel tee when about 1.2% chromium content in steel, chromium and oxygen effect of corrosive medium, in the steel surface to form a thin layer of oxide film (since the passivation film), seamless tee can prevent steel substrate further corrosion. In addition to the chromium, the commonly used alloying elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc, in order to meet the various USES of concentric reducer organization and performance requirements. Straight sealing three-way concentric reducer must be adopted in production of production and processing technology, guaranteed to show a good role in production and processing, and performance.
Concentric reducer tube is resistant to corrosion of steel by weak corrosive medium such as air, steam and water and chemical corrosive medium such as acid, alkali and salt.
