Introduction
Chlorinated polyvinyl chloride (PVC-C) pipes are resistant to acid and alkali corrosion and will not rust.
The flow area of the pipeline is reduced or even blocked due to the oxidation and corrosion of iron in the pipeline. When a fire occurs, high-pressure water spray is required but the water supply pressure of the pipeline
Insufficient power or even nozzle clogging and other problems. The application of chlorinated polyvinyl chloride (PVC-C) piping system as building fire protection piping in the United States and other foreign countries
It has been used for more than 30 years, and foreign experience proves that the product has good usability and safety under the premise of standardized construction, but
The popularization and application in our country has been relatively slow.
GB/T 39380 "Chlorinated Polyvinyl Chloride (PVC) Piping System for Sprinklers" series standards have key technical indicators such as pressure resistance of materials.
Standards are determined according to GB/T 18252-2020 (ISO 9080.2012), all grading requirements, long-term performance prediction theory and international standards
All are consistent to ensure the safe service life of the piping system for 50 years.
In view of the current development status of PVC-C compounding materials in my country and the mature application experience abroad for many years, GB/T 39380 also recognizes
Pipes made from PVC-C compounds that can be graded to grade 4120 according to ASTM D2837-13.This document was developed with reference to the
UL1821, ASTMF439, ASTMF438, ASTMF437 and other standards related to chlorinated polyvinyl chloride (PVC-C) pipes, in key
The technical indicators are consistent with the requirements of foreign standards.
GB/T 39380 consists of two parts.
--- Part 1.Pipes. The purpose is to standardize the requirements and test methods of chlorinated polyvinyl chloride (PVC-C) pipe products for sprinkler fire extinguishing
Laws, inspection rules and other relevant requirements;
--- Part 2.Fittings. The purpose is to standardize the requirements and test methods of chlorinated polyvinyl chloride (PVC-C) pipe fittings for sprinkler fire extinguishing
Laws, inspection rules and other relevant requirements.
In order to ensure the effective use and promotion of related products, and promote and standardize the development of the industry, it is formulated in parts according to different product functions.
For the design and installation technical specifications of this document, please refer to GB 50084-2017 "Code for Design of Automatic Sprinkler Fire Extinguishing" and other related documents.
Chlorinated polyvinyl chloride (PVC-C) for sprinkler
Piping systems part 2.fittings
1 Scope
This document stipulates that the chlorinated polyvinyl chloride (PVC-C) compounding material is used as the raw material, and the chlorinated polyvinyl chloride (CPVC) for sprinkler fire extinguishing is injection molded.
(PVC-C) pipe fittings (hereinafter referred to as "pipe fittings") materials, product classification, requirements, test methods, inspection rules and signs, packaging, transportation and
storage.
This document is applicable to the working pressure specified in GB 50084 not greater than 1.2MPa, and the ambient temperature not lower than 4°C and not higher than
70°C pipe fittings are used for automatic sprinkler systems in places where the fire hazard level is light hazard level and medium hazard level I.
This document, together with Part 1 of GB/T 39380, applies to the plastic piping system specified in GB 50084.
