Introduction

In order to ensure the interchangeability of thermoplastic pipe products for fluid transportation, it is necessary to unify the dimensions and tolerance levels of various types of pipes Provisions. In the past, tolerance classes for thermoplastic pipes were scattered among specific product standards. In most cases, product standards only give For the specific tolerance value, the user cannot know the tolerance level used, nor can he calculate the tolerance of other required dimensions when needed. The purpose of GB/T 42952 is to establish a unified standard covering the dimensions and tolerances of all thermoplastic pipes for fluid transportation. The grade standard is proposed to consist of two parts. ---Part 1.Metric series. ---Part 2.Imperial series. GB/T 42952.1 includes tolerance levels for average outer diameter, out-of-roundness, wall thickness at any point and average wall thickness. Responsible for drafting thermoplastic Each interested party in the material piping documentation can select the applicable tolerance level from this document. Terms and definitions relevant to this document can also be found in GB/T 19278. Thermoplastic pipes for fluid transportation Dimensions and Tolerances Part 1.Metric Series

1 Scope

This document specifies the outer diameter, out-of-roundness and wall thickness of thermoplastic pipes for fluid conveyance in compliance with the requirements of ISO 161-1 and ISO 4065.
