Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1. Structure and Drafting Rules of Standardization Documents" drafted.

This document is the second part of GB/T 41004 "Intelligent Pipe Network System". GB/T 41004 has released the following parts.

--- Part 1. General;

--- Part 2. Intelligent plastic pipes, fittings and valves.

Introduction

The intelligent pipe network system uses advanced computer technology, network communication technology, artificial intelligence technology, etc. to realize the remote control of the pipe network system.

Monitor and control, obtain real-time information such as pressure, flow, flow rate, pipeline noise, etc.

Accurate and efficient digital information. At present, there are practical applications of intelligent pipe network systems in my country's water supply, drainage, gas, and heat pipe networks. use. GB/T 41004 "Intelligent Pipe Network System" aims to establish the rules generally applicable to the production, design, laying and application process of intelligent pipe network system. Fan, it is proposed to be composed of three parts.

--- Part 1. General. The purpose is to establish the basic information, basic information involved in the intelligent pipe network system suitable for design, laying and application. These requirements and related rules of information security.

--- Part 2. Intelligent plastic pipes, fittings and valves. The purpose is to standardize the product requirements of intelligent plastic pipes, fittings and valves. requirements, test methods, inspection rules, etc.

--- Part 3. Intelligent metal pipes, fittings and valves. The purpose is to standardize the product requirements of intelligent metal pipes, fittings and valves. requirements, test methods, inspection rules, etc.
