Abstract

The invention discloses a reinforced thermoplastic plastic pipe which is relatively light in weight and is largely increased by pressure resistant performance, which comprises an inner layer pipe and an outer layer pipe. The reinforced thermoplastic plastic pipe is characterized in that a reinforced layer is further arranged between the inner layer pipe and the outer layer pipe, and the reinforced layer is wound by at least two layers of basalt fibers which are treated by plasma. The weight of the reinforced thermoplastic plastic pipe is only the one-quarter of a steel pipe, pressure resistant performance is greatly increased, the pipe can bear 800 Pa pressures, and is long in service life and strong in erosion resistance, besides, the plastic pipe can be processed into a pony roll in hundreds of meters, and is more convenient in paving and less in connector. The plastic pipe can be widely applied to conveying crude oil, acid natural gas and the like.

Description

technical field

[0001] The present invention relates to a reinforced thermoplastic pipe. Background technique

[0002] Reinforced thermoplastic pipes (RTP pipes for short) are used more and more widely, and are now available in places with special requirements, such as transporting crude oil and sour gas at pressures up to 100bar. A currently used reinforced thermoplastic pipe includes an inner tube and an outer tube made of high-density polyethylene material (HDPE), and a steel strip, steel wire, glass fiber or Reinforcement made of aramid fibers. The disadvantage of pipes made of steel belt or steel wire as reinforcement is that they are heavy and inconvenient for transportation and construction; the disadvantage of pipes made of glass fiber or aramid fiber as reinforcement is that the pressure resistance is not high and cannot Some special requirements are met.
