Introduction

Glass fiber reinforced plastic pipe is a composite material with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as matrix materials.

Plastic pipes are widely used in the oil and gas industry. In order to standardize the design, manufacture, evaluation and operation of glass fiber reinforced plastic pipes

A series of technical documents for glass fiber reinforced plastic pipes in the oil and gas industry have been formulated. GB/T 29165 "Oil and Natural Gas Industrial Glass

Fiber Reinforced Plastic Pipe" aims to provide the oil and gas industry with the basic terms, materials, evaluation,

Standards for manufacture, design, assembly, installation and operation. According to the characteristics of each stage of the full service cycle of glass fiber reinforced plastic pipes, such as application and

Materials, evaluation and manufacture, system design, assembly, installation and operation, GB/T 29165 consists of four parts.

--- Part 1.Vocabulary, symbols, applications and materials. The purpose is to provide information on basic terminology and notation for the remaining three sections, and to

Applications and materials are specified and required.

--- Part 2.Evaluation and manufacture. The purpose is to guide the system design, assembly of glass fiber reinforced plastics (GRP), and to provide

Quality requirements for assessing and manufacturing products.

--- Part 3.System Design. The aim is to provide a system design for the entire glass fiber reinforced plastic (GRP) piping system piping.

--- Part 4.Assembly, installation and operation. The purpose is to provide construction parties and users of glass fiber reinforced plastic (GRP) systems

refer to.

Compared with traditional metal materials and other non-metal material pipes, glass fiber reinforced plastic pipes have high strength, good performance, and product design

The degree of freedom is large, and the product has a wide range of applications. This document combines the specific use of glass fiber reinforced plastic pipes in the petroleum industry.

According to the characteristics of each stage of its life cycle, it can guide all parties including the designer, manufacturer, construction party and user to provide glass

The application of fiber-reinforced plastic pipes in the petroleum industry provides a complete system solution to ensure the safety regulations of products in the petroleum industry

use.
