Embodiment

[0014] A method for connecting socket ring-pressed metal pipe fittings, the process steps are as follows:

[0015] (1) Select the pipe material that matches the pipe diameter of the socket ring-pressed metal pipe fitting, and cut it according to the set length. As a preference, set the length of the pipe material to 6 meters.

[0016] (2) Grind the incision of the cut pipe on the grinding tool, polish the incision until smooth, remove the surrounding burrs and burrs, and use a portable grinder or file as the grinding tool.

[0017] (3) introducing the pipe material treated in step (2) between the ring pressure part and the socket part of the socket ring pressure metal pipe fitting, and inserting it into the bottom;

[0018] (4) Use the ring pressure hydraulic tool to lock the ring pressure part of the socket ring pressure metal pipe fitting, press it according to the specified pressure, and finally connect the pipe and the pipe fitting.

Abstract

The invention discloses a connecting method for a socket ring pressing type metal pipe fitting, which comprises the steps of: (1) selecting a pipe the diameter of which is matched with that of the socket ring pressing type metal pipe fitting, and cutting the pipe according to set length; (2) grinding the cut of the cut pipe on a grinding tool till the cut is ground to be smooth and the burrs on the periphery are removed; (3) leading the pipe processed in step (2) into the space between the ring pressing part and the socket part of the socket ring-pressing type metal pipe fitting, and inserting the pipe into the bottom part; and (4) locking the ring pressing part of the socket ring-pressing type metal pipe fitting by a ring pressing hydraulic tool, and pressing the ring pressing part tightly by specified pressure. In the connecting method for the socket ring-pressing type metal pipe fitting, the socket ring pressing connection mode is adopted, therefore, the sealing property between the pipe and the socket ring-pressing type stainless steel metal pipe fitting is higher; and the socket ring-pressing type metal pipe fitting is adopted, thereby enabling the construction and installation to be more convenient, and completely eradicating potential safety hazard of sealing.

Description

technical field [0001] The invention relates to a connection process method of pipe fittings. Background technique [0002] Pipe fittings, as the basic components that connect pipes into pipelines, have a large number of applications in water supply, gas supply, chemical and construction industries. According to the division of raw materials, pipe fittings are generally divided into plastic pipe fittings and metal pipe fittings. The characteristics of the two are different. : Plastic pipe fittings are low in cost and light in weight, but they are easy to age, low in strength, weak in pressure resistance, poor in light radiation resistance, and relatively short in service life; metal pipe fittings are beautiful in appearance, durable, strong in corrosion resistance, and long in service life . However, there is still no good solution for the connection between metal pipe fittings and pipes. At present, the connection between stainless steel metal pipe fittings and metal pipe...
