Leqing Explosion-Proof Pipe Fitting Supply & Sales_Prices_Full Specifications Available_Stock Availability [Leqing Zhenlei Explosion-Proof Electrical Equipment Co., Ltd.] Explosion-proof pipe fittings are used to connect explosion-proof pipelines, ensuring the safety and sealing of the pipeline system in flammable and explosive environments, preventing gas or dust leakage that could cause accidents. I. Structural Features Material Selection: Metal materials such as stainless steel, carbon steel, brass, etc., with high strength, corrosion resistance, and high-temperature resistance. Sealing materials such as rubber, PTFE, etc., to prevent leakage under high pressure, high temperature, or corrosive media. Structural Design: Threaded connection: Uses internal or external threading or a combination of both, for easy installation and disassembly. Flange connection: Suitable for large-diameter pipelines, fixed by flange and bolts for a secure connection. Clamp connection: Achieves quick connection with clamps and seals, suitable for frequent disassembly. Explosion-proof design: Explosion-proof grade: Select the appropriate explosion-proof grade according to the operating environment (e.g., Exd IIC, Exe). Sealing structure: Uses metal-to-metal sealing, elastic sealing, etc., to ensure no leakage in explosive environments. II. Performance Parameters Pressure Rating: Select the appropriate fitting according to the working pressure of the pipeline system, common pressure ratings include PN10, PN16, PN25, etc. Temperature Range: Select high-temperature or low-temperature-resistant fittings according to the medium temperature, typically ranging from -40℃ to +200℃. Explosion-proof Grade: Exd IIC: Suitable for Class II, Group C explosive gas environments. Exe: Suitable for increased safety explosion-proof applications. Protection Class: Such as IP66, IP67, indicating the dust and waterproof performance of the fitting. III. Application Scenarios Petroleum & Chemical Industry: Refineries, chemical plants, natural gas processing plants, etc., for the transportation of flammable and explosive media. Coal Mine: Underground ventilation systems, gas drainage systems in coal mines, etc., to prevent gas leakage. Pharmaceutical Industry: Pipeline transportation of flammable solvents used in the production process. Food Processing: Pipeline transportation of flammable dusts such as flour and sugar powder.
