Carbon steel tees are generally used for the installation of control valves, and use draining. The concentric reducer is conducive to fluid flow, and has less interference to the fluid flow pattern when the diameter is changed.
Seamless three-way, so gas and vertical liquid pipelines use concentric reducers to reduce the diameter. The eccentric reducer is flat on one side, which is good for exhaust or liquid discharge, and is convenient for driving and maintenance. Therefore, the eccentric reducer is generally used for horizontally installed liquid pipelines.
The reducing pipe is also called the size head. The diameters of the nozzles at both ends are different, and they are used to connect pipes or flanges of different diameters for diameter reduction. The two ends of the concentric reducing pipe have the center of the circle on the same axis. When the diameter is reduced, the position of the pipe is calculated by the axis, and the position of the pipe remains unchanged. It is generally used for gas or vertical liquid pipe diameter reduction. The eccentric reducer is inscribed in the circumference of the nozzles at both ends, and is generally used for horizontal liquid pipelines.
Butt welding tee is a steel elbow formed by hot pressing or forging. Its connection form is to directly butt weld the tee with the steel pipe. The main manufacturing standards for butt welding tee are generally GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.
Butt welding tees generally have equal diameter tees, reducing tees, etc. The materials are carbon steel, alloy steel and stainless steel.
Carbon steel tee When the chromium content in the steel reaches about 1.2%, the chromium interacts with the oxygen in the corrosive medium to form a very thin oxide film (self-passivation film) on the surface of the steel. The seamless tee can stop the steel The matrix is further corroded. In addition to chromium, commonly used alloying elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements for the structure and performance of concentric reducers for various purposes. Certain production and processing techniques are used in the production of diameter pipes to ensure that they can show good effects and performance in production and processing.
Concentric reducer steel that is resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. In practical applications, it is often resistant to weak corrosive media
