Concentric reducers are beneficial to fluid activities and have less interference to fluid flow regimes during reducing diameters.
Seamless tee for liquid and gas pipe, using concentric reducer to reduce diameter. Because the eccentric reducer is flat on one side, it is convenient for exhausting and draining, which is convenient for operation and maintenance. Therefore, the liquid pipeline of the horizontal device generally uses an eccentric reducer.
The reducer is also called the size head. The diameters of the two nozzles are different. They are used to connect pipes or flanges of different diameters for diameter reduction. The nozzle of the concentric reducer, the center of the circle is on the same axis, when the diameter is reduced, and the orientation of the tube is calculated by the axis, the orientation of the tube is constant, and 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.
Butt welding tee is a steel hot press forming or forging forming elbow. Its connection method is to directly weld the tee and the steel pipe. The main production standards of the butt welding tee are generally GB/T12459, GB/T13401., ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.
