Seamless pipe fittings Characteristics
Functions of seamless reducers
Carbon steel tees (pipe fittings) are generally used to adjust the valve to facilitate drainage. The concentric reducer facilitates fluid activity and has less interference with fluid flow at the time of variable diameter.
The diameter of the two ends of the reducer is different, and it is used to connect steel pipes or flanges of different diameters to reduce the diameter. The two nozzles of the concentric reducer have the center of the circle on the same axis. When the diameter is changed, the orientation of the pipe is unchanged according to the axis. Generally, the orientation of the steel pipe is constant, and it is generally used for gas or straight liquid pipe diameter reduction. The eccentric reducer is internally cut at the ends of the two nozzles and is generally used for horizontal liquid pipes.
Standard of Butt welding Tees
Butt welding tee is the connections of hot stamping or forging forming of steel plate. The connection method is to directly weld the tee and steel pipe. The main production standards of butt welding tees are generally GB/T12459, GB/T13401, ASME. B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.
Related information of seamless Tees
Butt welding tees generally have equal-diameter tees, different-diameter tees, etc. The materials are carbon steel, alloy steel and stainless steel. Carbon steel tee When the chromium content of the steel reaches 1.2%, the chromium reacts with the oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the steel surface. The seamless tee can prevent further corrosion of the steel tube. In addition to chromium, commonly used alloying elements include nickel, molybdenum, titanium, niobium, copper, and nitrogen to meet various applications.
