Abstract

The invention discloses a reinforced thermoplastic plastic pipe which is characterized by consisting of the following raw materials in parts by weight: 90-97 parts of PE80, 2-3 parts of zinc phosphate, 3-5 parts of carbon fiber, 2-3 parts of polyisobutene, 0.2-1 part of pyromellitic dianhydride, 1-2 parts of linoleic acid, 1-2 parts of octyl-4-isothiazolin-3-one, 2-3 parts of biimidazoline-ammonium-salt corrosion inhibitor, 2-4 parts of nano fluorite powder, 2-3 parts of glass powder, 0.8-1 part of octyl tin mercaptan OTM-17N, 0.8-2 parts of 2-mercapto benzimidazole and 10-13 parts of composite filler. The pipe is particularly suitable for long-distance transport pipes and offshore oil and gas fields, is high in corrosion resistance and has high damage resistance, and a leakage phenomenon is avoided.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a reinforced thermoplastic pipe. Background technique [0002] For traditional steel pipes, although affected by corrosion and other factors, problems such as leakage or even bursting may occur, but due to the relatively mature detection and repair technology of steel pipes, oil and gas fields are familiar with their repair and detection, and can be used for existing pipelines. On-line detection of the state of the steel pipe, if any leaks or damages are found in the steel pipe, it can be repaired by reinforcement, welding and other technologies. But for RTP pipes, while non-metallic materials avoid corrosion problems, their electrical insulation makes many detection methods suitable for metal pipes helpless. The current damage repair method of RTP pipe is to use a new pipe to replace the damaged pipe section, which requires joint processing on site. Since the RTP pipe connection p...
