The technical differences between this document and ISO 14692-4:2017 and their reasons are as follows:

---Because there is no institution in my country that is capable of carrying out the certification work specified in Appendix C, Appendix C is changed from a normative appendix to an informational one:

appendix:

The following editorial changes have been made to this document:

a) A flow chart has been added to the introduction, and the numbers of subsequent figures have been postponed;

b) In 4:5:5, the informative reference to AWWAM45:2013 was deleted;

c) In 4:6:2, modify "integrity test" to "strength test" and modify "leakage test" to "tightness test";

d) In Appendix C, the table number and title "Table C:1 Explanation of Responsibilities of Certification Parties" are added to the first table, and others the table numbers are extended in sequence;

e) In Appendix C, the "informative" part of Table C:12 is deleted:

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: This document is intended to provide the oil and gas industry with Recognized standards for basic terminology, materials, evaluation, manufacture, design, assembly, installation and operation of fiberglass reinforced plastic pipes: According to glass Characteristics of each stage of the full service life of glass fiber reinforced plastic pipes, such as application and materials, evaluation and manufacturing, system design, assembly, installation and operation OK, GB/T 29165 "Glass Fiber Reinforced Plastic Pipes for the Oil and Gas Industry" is planned to consist of four parts:

---Part 1: Vocabulary, symbols, applications and materials: The purpose is to stipulate the application range and pressure evaluation of glass fiber reinforced plastic pipes:

Determining methods and classifications, terminology, definitions and symbols, and providing guidance for other parts of GB/T 29165:

---Part 2: Assessment and Manufacturing: The purpose is to specify the quality assessment and manufacturing requirements for glass fiber reinforced plastic pipes and fittings:

---Part 3: System Design: The purpose is to provide specifications for the design of fiberglass reinforced plastic piping systems:

---Part 4: Assembly, installation and operation: The purpose is to provide for the assembly, installation, maintenance and Repair requirements:

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

This document combines the characteristics of large degree of freedom and wide range of product applications: This document combines the specific use of glass fiber reinforced plastic pipes in the oil and gas industry:

Based on the characteristics of each stage of its full service life, it can guide all parties including designers, manufacturers, constructors and users to provide guidance for Glass fiber increases the application of plastic pipes in the oil and gas industry, providing a complete system solution to ensure that the products are used in the oil and gas industry:
