Introduction
Coilable reinforced plastic pipes have been rapidly developed due to their excellent pressure resistance and medium corrosion resistance. In various industries, especially stone
The oil and petrochemical industry is more and more widely used. There are various choices of materials for the inner tube and reinforcement layer of this kind of pipeline, according to the different reinforcement layers.
It can be divided into non-metal reinforced coiled pipe and metal reinforced coiled pipe; according to the different inner pipe materials, it can be divided into polyethylene coiled pipe, heat-resistant poly
Ethylene coiled tubing, cross-linked polyethylene coiled tubing, polypropylene coiled tubing, polyamide coiled tubing, polyvinylidene fluoride coiled tubing, etc.;
It can be divided into bonded coiled tubing and non-bonded coiled tubing. GB/T 38725 aims to establish the standards applicable to the drafting, formulation and
The guidelines for organizing work are proposed to consist of three parts.
--- Part 1.General. The purpose is to specify general guidelines to be followed for coilable reinforced plastic pipes.
--- Part 2.Fiber-reinforced thermoplastic coiled tubing. The purpose is to specify the requirements for products of fiber-reinforced thermoplastic coiled tubing.
Performance, inspection, packaging, transportation and storage requirements.
--- Part 3.Metal-reinforced thermoplastic coiled tubing. The purpose is to specify the product specification of metal reinforced thermoplastic coiled tubing.
Performance, inspection, packaging, transportation and storage requirements.
