Ansi/Asme B16.9 Butt Weld Equal Tee Manufacturer In China

The utility model discloses a steel butt welding seamless tee pipe fitting forming die, which belongs to a production die for tee pipe fittings, comprising a chassis, a fixed concave die, a movable concave die, an upper punch, a lower punch and a hydraulic mechanism. The characteristic is that there are concave die cards on both sides of the concave die, a nozzle insert and a floating counter-punch are installed in the fixed concave die, the upper die seat is connected to the lower die seat through a push rod and a rubber spring, and the lower die seat is connected to the lower die seat. A rubber spring is arranged between the chassis. The utility model has reasonable structure, stable operation, one-time molding, high production efficiency and good quality, and is an ideal tee pipe fitting forming mold.

The hydraulic bulging process of the tee can be formed at one time, and the production efficiency is high; the wall thickness of the main pipe and the shoulder of the tee are increased.

Due to the large tonnage of equipment required for the hydraulic bulging process of seamless tee, it is currently mainly used in the manufacture of standard wall thickness tee less than DN400 in China. The applicable forming materials are low carbon steel and stainless steel with relatively low cold work hardening tendency.
