Introduction

Glass fiber reinforced plastic pipe is a composite made of 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, manufacturing, evaluation and operation of glass fiber reinforced plastic pipes line, and formulated a series of technical documents for glass fiber reinforced plastic pipes for the oil and gas industry: GB/T 29165 "Oil and natural gas industrial glass Fiber Reinforced Plastic Pipes" aims to provide the oil and gas industry with basic terminology, materials, evaluation, and evaluation of glass fiber reinforced plastic pipes recognized by all parties:

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 manufacturing, system design, assembly, installation and operation are planned to be composed 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 parts, and to Application scope and materials are specified and required:

---Part 2: Assessment and Manufacturing: The purpose is to provide quality for the design, assembly and compliance of glass fiber reinforced plastic (GRP) systems:

Assessment and product manufacturing:

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

---Part 4: Assembly, installation and operation: The purpose is to provide constructors and users of glass fiber reinforced plastic (GRP) systems with for guidance:
