Carbon steel three-way pipe fittings are generally used for regulating valve devices, and use draining. The concentric reducer is conducive to fluid flow, and has less interference to the fluid flow pattern when the diameter is reduced. 　　

      Seamless three-way pipe fittings, so gas and straight liquid pipelines use concentric reducers to reduce the diameter. Because one side of the migraine reducer is flat, it is good for exhaust or liquid drainage, and is convenient for driving and maintenance. Therefore, the liquid pipeline of the horizontal device is generally a migraine reducer.

     The reducing pipe is also called the size head, and the two pipe ports have different diameters, which are used to connect pipes or flanges of different diameters for diameter reduction. The two nozzles of the concentric reducer have the center of the circle on the same axis. When calculating the tube position with the axis, the tube position will not change. It is generally used for gas or straight liquid pipe diameter reduction. The two ends of the migraine reducer are inscribed in the circumference, which is generally used for horizontal liquid pipelines.

      Butt-welded tee fittings are steel elbows formed by hot pressing or forging. Its connection form is to directly butt-weld tee fittings with steel pipes. The main manufacturing specifications for butt-welded tee fittings are generally GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.

     Butt-welded tee fittings generally include equal diameter tee fittings, reducing tee fittings, etc. The materials are carbon steel, alloy steel and stainless steel.

      Carbon steel three-way pipe fittings When the chromium content in the steel reaches about 1.2%, the chromium and the oxygen in the corrosive medium form a very thin oxide film (self-passivation film) on the surface of the steel. Seamless three-way pipe fittings can be Prevent further corrosion of the steel matrix. 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 applications. When producing concentric reducers, certain production and processing techniques are used to ensure that good effects and performance can be displayed in production and processing.
