WPB Tee

WPB Tee Introduction

Wpb is the American standard pipe fitting material, which is generally made of carbon steel j and alloy steel. W is butt welding, P is pipe and pipe fitting, and B is grade B carbon steel pipe. It is forged carbon steel and alloy steel pipe fittings for high temperature, with chemical composition of C ≤ 0.03, Mn=0.29~1.06, P ≤ 0.05, S ≤ 0.058, Si ≥ 0.10, Cr ≤ 0.40, Mo ≤ 0.15, Ni ≤ 0.40, Cu ≤ 0.40, V ≤ 0.08., It is used for carbon steel elbow, tee, reducer, pipe cap, elbow and other products. Wpb is one of A234 standard grades, and also includes WP5, WP9, WP11, WP12, WP22, WP91 and other carbon steel and alloy steel grades

WPB three-way pipe fittings are generally used for regulating valve devices, and drainage is adopted. Concentric pipe is favorable for fluid flow, and the change of diameter has less interference on fluid flow pattern

Therefore, WPB tee fittings use concentric pipes with different diameters to enter the actual main body and vertical flow liquid pipes. Since one side of pipes with different diameters is flat, which is conducive to draining or discharging liquid and is convenient for startup and maintenance, liquid pipes of horizontal devices are generally used for pipes with different diameters

Pipes with different diameters are also called reducers. The diameters of pipe orifices at both ends are different, and they are used to connect pipe fittings or flanges with different diameters for diameter changes. At both ends of concentric and different diameter pipes, the center of the circle is on the same axis. When the pipe diameter changes, if the axis is used to calculate the orientation of the pipe, the azimuth of the pipe will remain unchanged, which is usually used to change the diameter of gas or vertical liquid pipes. Circumferential cutting at both ends of pain tubes with different diameters is generally used for horizontal liquid tubes

WPB tee pipe fittings are elbows made of steel by hot pressing or forging, and their connection mode is to directly weld tee pipe fittings with steel pipes. The main manufacturing technical indicators of WPB tee fittings are GB/T 12459, GB/T 13401, ASMEB 16.9, SH 3408, SH3409, HG/T21635, HG/T21631, SY/T0510
