ASME B16.5 WP321 / 347 Seamless Equal Diameter Tee/Cross Stainless Steel Pipe FittingsASME B16.5 WP321 / 347 Seamless Eq

The stamping equal diameter tee is the stamped tee, also known as the positive tee. It is generally used in high-pressure pipelines and other projects. The specifications and models are generally within DN600. According to the process, it can be divided into cold drawn tee and hot pressed tee. The production process of the stamping tee is to first place the tube blank in the lower mold, then press the upper mold, and then make the shaft heads at both ends press against the ends of the tube blank, and then pass the high pressure liquid through the center hole of the shaft head. Under the combined action of axial compression force, bulge to obtain the required parts. The bulging method that uses the combined action of axial compression and high-pressure liquid. Bulging belongs to the category of stamping.

Welding tee is a section of main pipe plus a small branch pipe.

Obviously, the two larger sizes are main pipes, and the smaller one that comes out of them is the branch pipe. In pure oxygen pipelines, there is usually pressure, and the oxygen is active. Larger; if the welding tee is used, as long as the debris in the pipe moves with the oxygen flow, the change in the flow rate due to the change of the pipe diameter may cause the collision of the debris and the pipe to produce the fire source or the electrostatic discharge due to the change of the flow velocity. All may cause the pure oxygen tube to catch fire. Welding tee is widely used in petroleum, aerospace pharmaceutical, chemical, metallurgy, electric power, military, engineering supporting and other industrial pipelines.
