ICS 71:120 CCSG94 National Standards of People's Republic of China Permeability testing methods for chemical equipment Part 2: Fiber-reinforced thermoset plastic equipment Published on 2023-11-27 2024-06-01 Implementation State Administration for Market Regulation Released by the National Standardization Administration Committee ForewordThis 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 41312 "Permeability Testing Methods for Chemical Industry Equipment": GB/T 41312 has released the following part: ---Part 1: Graphite and its lining equipment; ---Part 2: Fiber-reinforced thermosetting plastic equipment; ---Part 3: Plastics and their lining equipment: Please note that some content in this document may be subject to patents: The publisher of this document assumes no responsibility for identifying patents: This document is proposed by China Petroleum and Chemical Industry Federation: This document is under the jurisdiction of the National Technical Committee for Standardization of Non-Metallic Chemical Equipment (SAC/TC162): This document was drafted by: Nanjing Xinhe Composite Materials Co:, Ltd:, Jiangsu Special Equipment Safety Supervision and Inspection Institute, Ningbo Special Equipment Inspection Research Institute, Shuangdun Environmental Technology Co:, Ltd:, East China University of Science and Technology Huachang Polymer Co:, Ltd:, Jiangyin Jiangnan Fluoroplastic Co:, Ltd: Division, Chengde Precision Testing Machine Co:, Ltd: The main drafters of this document: Shi Qiang, Zhang Yanbing, Chen Daoyan, Shi Jiantao, Wang Du, Pu Jiang, Chen Wenfei, Cao Wei, Liu Shiqiang, Fu Jianming, Wang Chunyan, Liu Ying, Li Zhongjiang, Yang Meng:IntroductionGB/T 41312 is designed to accurately measure the resistance to media penetration of non-metallic and lining equipment used in the chemical industry and consists of 3 parts: ---Part 1: Graphite and its lining equipment: The purpose is to measure the permeability properties of graphite and its lining equipment: ---Part 2: Fiber-reinforced thermoset plastic equipment: The purpose is to measure the permeability properties of fiber-reinforced thermoset plastic equipment: ---Part 3: Plastics and lining equipment: The purpose is to measure the permeability properties of plastics and their lining equipment: The resistance to medium penetration is very important for non-metallic chemical equipment: It is directly related to the safety and service life of the equipment: Due to its excellent anti-corrosion performance and heat resistance, non-metallic chemical equipment is mainly used to contain highly corrosive and extremely toxic materials: Highly hazardous media: If the equipment has poor anti-penetration performance due to problems such as raw materials and manufacturing processes, and the contained medium can penetrate, it will be dangerous: and personal safety, causing environmental pollution: Since graphite and its lining equipment, fiber-reinforced thermosetting plastic equipment, and plastic and its lining equipment are three different materials and structures, Chemical equipment with different usage ranges has different applicable media, temperature and pressure ranges: Therefore, the three permeability detection methods Different from each other, in order to accurately detect the permeability of three types of chemical equipment, the permeability detection methods are described in three parts: This article After the release and implementation of the software, it will play a very good guiding role in the permeability testing of chemical fiber reinforced thermosetting plastic equipment and improve the quality of the equipment: It is of great significance to improve the quality level and standardize the manufacturing process of equipment: Permeability testing methods for chemical equipment Part 2: Fiber-reinforced thermoset plastic equipment1 ScopeThis document specifies the principles, test pieces, specimens, and test equipment of the liquid permeability testing method for fiber-reinforced thermosetting plastic equipment used in the chemical industry: settings, test procedures, result judgments and test reports: This document is suitable for testing the liquid penetration resistance of fiber-reinforced thermosetting plastic equipment used in chemical industry:2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document: GB/T 150:3 Pressure vessels Part 3: Design GB/T 34329 General requirements for fiber reinforced plastic pressure vessels3 Terms and definitionsThere are no terms or definitions to be defined in this document:4 PrinciplesFill the closed equipment or test device with liquid test medium and pressurize it to the test pressure: If necessary, heat the test medium and sample: to the set test temperature, the test medium is forced to penetrate from one side of the fiber-reinforced thermosetting plastic lining layer to the other side through pressure: When the test pressure After the force is maintained for the set time, observe whether there is penetration of the test medium on the opposite side of the fiber-reinforced thermosetting plastic lining layer to make a result: judgment:5 Test device5:1 Test device when the test specimen is equipment When using equipment as a test specimen, the test device is shown in Figure 1: ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41312.2-2023_English be delivered?Answer: Upon your order, we will start to translate GB/T 41312.2-2023_English as soon as possible, and keep you informed of the progress.
