Glass-fiber-reinforced-plastic high-pressure petroleum conveying pipe capable of being connected rapidly

Abstract

The invention discloses a glass-fiber-reinforced-plastic high-pressure petroleum conveying pipe capable of being connected rapidly. The glass-fiber-reinforced-plastic high-pressure petroleum conveying pipe comprises a pipe body, a stop ring and a seal ring. An insertion opening is formed in one end of the pipe body, and a receiving opening is formed in the other end of the pipe body. The outer circumferential face of the outer side of the insertion opening protrudes outwards to form a frustum-shaped oblique face, and thereby a stop platform is formed between the inner side and the outer side of the insertion opening. The inner circumferential face of the receiving opening is sunken from outside to inside in a spaced manner to form a first arrangement ring and a second arrangement ring. The stop ring is arranged at the position, located on the inner circumferential face of the outer side of the first arrangement ring, on the receiving opening. The seal ring is mounted inside the second arrangement ring, and a boss is formed in the position, close to the inner side of the second arrangement ring, on the inner circumferential face of the receiving opening and used for clamping the outer end of the insertion opening. The glass-fiber-reinforced-plastic high-pressure petroleum conveying pipe has the beneficial effects of being small in weight, rapid to connect, high in strength, capable of being repaired rapidly, resistant to corrosion and static electricity, retardant to flames, resistant to collision and aging, smooth in inner wall, resistant to high pressure and the like.

Description

technical field [0001] The invention belongs to the technical field of FRP pipeline manufacturing, in particular to a FRP high-pressure oil pipeline capable of fast connection. Background technique [0002] At present, my country's emergency rescue, emergency rescue and field oil pipelines still use the technology of the former Soviet Union. Many defects: ①Each 6-meter-long oil pipeline weighs 60-80 kilograms, and two people are required to move and lay it, and the laying site is often in the wild with complex terrain, so a lot of labor is required: ②The pipe wall and The joints are all welded, and the defects of the welds are easy to leak and tear; ③Although the inner wall of the pipe is coated with an anti-corrosion layer, when the anti-corrosion layer is damaged, defects such as corrosion pits will occur, so long-term use will cause pipeline damage. Leakage, rupture or even explosion will undoubtedly seriously affect rescue operations. Contents of the invention [0003] ...
