GB/T 10002.2-2023Unplasticized poly (vinyl chloride) (PVC-U) fittings for water supply (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document is Part 2 of GB/T 10002.GB/T 10002 has published the following parts.

---Part 1: Rigid polyvinyl chloride (PVC-U) pipes for water supply;

---Part 2: Rigid polyvinyl chloride (PVC-U) pipe fittings for water supply;

---Part 3: Rigid polyvinyl chloride (PVC-U) valves for water supply.

Introduction

Plastic pipes and pipe fittings are widely used in urban tap water supply projects, internal and external building water supply projects, and farmland water conservancy and irrigation.

Engineering, water supply projects for industrial and mining enterprises, water supply projects for landscaping and greening, aquaculture water supply and drainage projects, etc.

GB/T 10002 aims to standardize the production and use of rigid polyvinyl chloride (PVC-U) pipes, fittings and valves for water supply. The olefin piping system consists of the following 3 parts.

---Part 1: Rigid polyvinyl chloride (PVC-U) pipes for water supply, the purpose is to standardize the technology of rigid polyvinyl chloride pipe products for water supply technical requirements;

---Part 2: Rigid polyvinyl chloride (PVC-U) pipe fittings for water supply, the purpose is to standardize the technology of rigid polyvinyl chloride pipe fittings for water supply technical requirements;

---Part 3: Rigid polyvinyl chloride (PVC-U) valves for water supply, the purpose is to standardize the technology of rigid polyvinyl chloride valve products for water supply technical requirements.

Among them, Part 2 was first published as GB/T 10002.2-1988 in 1988, revised for the first time in 2003, and later changed to GB/T 10002.1- Replaced in 2006 and reformulated this time.

1 Scope

This document specifies the rigid polyvinyl chloride (PVC-U) compound used as raw material, which is injection molded and pipe-bent.

Materials, product classifications, requirements, system applicability, inspection rules, marking, packaging and transportation of vinyl chloride (PVC-U) pipe fittings (hereinafter referred to as "pipe fittings") Transmission, storage, and test methods are described.

This document is applicable to rigid polyvinyl chloride (PVC-U) pipe systems for underground water supply in buildings or outdoors with water temperatures not exceeding 45°C, including Pressure water transmission and potable water distribution for general purposes. This document also applies to pressure drainage piping systems.

Note 1. For the pressure reduction coefficient at operating temperatures between 0°C and 45°C, see Appendix A in GB/T 10002.1-2023.

Note 2. The purchaser is responsible for appropriately selecting the products specified in this document based on its specific application needs and in conjunction with relevant regulations, standards or specifications.
