It is planned to be divided into three parts. composition. --- Part 1.Graphite and its lining equipment; --- Part 2.Equipment for plastic fiber composite materials; --- Part 3.Plastics and their lining equipment. Penetration performance is very important to chemical equipment, it is directly related to the quality, safety and service life of chemical equipment. Due to its excellent anti-corrosion performance and heat-resistant performance, chemical equipment is used to contain extremely or highly hazardous toxicity. If the medium is easy to penetrate due to its manufacturing process and other problems, it will cause the leakage of toxic medium, endanger human safety, and cause environmental damage. environmental pollution and other vicious events. After the release and implementation of this document, it will play a very good guiding role in the permeability detection of chemical equipment, and will play a role in improving the chemical industry. The quality level of equipment and the specification of the manufacturing process of equipment in this industry are of great significance. Chemical equipment permeability detection method Part 1.Graphite and its lining equipment1 ScopeThis document describes the principle of the permeability detection method for chemical impermeable graphite equipment, and specifies the test equipment and materials, samples, Test procedure and test report. This document applies to the permeability testing of impermeable graphite equipment, but not to impermeable graphite equipment towers and graphite equipment lined with graphite plates. Prepared penetration testing.2 Normative referencesThere are no normative references in this document.3 Terms and DefinitionsThere are no terms and definitions that need to be defined in this document.4 PrinciplesAfter the impermeable graphite container or the closed space inside the sample is pumped to a certain degree of vacuum, helium gas of a certain purity and pressure is injected, and the pressure is maintained to a certain degree. After time, the leaked helium gas was detected by a helium mass spectrometer leak detector on the outside of the container and the sample.5 Test equipment and materials5.1 Detection system 5.1.1 The permeability detection system, see Figure 1. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41312.1-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 41312.1-2022_English as soon as possible, and keep you informed of the progress.
