The pipe opening device is an internal punching mechanism. It is the most advanced, simple and fastest hollow metal tube forming machine. It needs no drilling, and the punching and flanging are completed at one time. Metal tube hole flanging is the use of physical principle of stamping, the pneumatic system provides the power system or the oil from the metal pipe, mechanical application of punching device and metal pipe drawing hole flanging mold, stamping punching forming directly from the inside to the outside effect of metal tube, this operation is called a pulling hole, drilling, hole, open hole, perforation, reaming, drilling.
With pressure opening, the construction technology is advanced. It can be operated with pressure, no parking, no stopping and no production. The operation is carried out by using no fire sealing machine to ensure the safety of operation, and the whole construction process will not cause any pollution. With several ways of opening pressure: pressure holes are mainly vertical hole, pipe, pipe, pipe clamp hole open hole and pipe inverted hole, hole form several tanks.
