Fire Protection Engineering Pipe Joint Tight Seal Rubber Flange Gasket

A1: It works well for common water, air, neutral gas, and weak acid & alkali liquids. It is suitable for municipal water pipelines, ventilation ducts and general industrial fluid pipelines. It is not recommended for strong corrosive solvents and high-concentration chemical oil.

A2: Yes. The rubber's viscoelastic structure absorbs shocks from pump vibration and water hammer, protecting pipe welding joints. It can lower equipment running noise by 10-15dB for a quieter operating environment.

A3: It will not stick tightly to flange surfaces. No sticky residue remains after disassembly, and you do not need extra cleaning work on the flange face during pipeline maintenance.

A4: Conventional rubber gaskets adapt to working temperatures from -20 to 80 tempurature. Stable elasticity and sealing performance are maintained within this range without hardening or cracking.

A5: They are applied for flange sealing on municipal water supply & drainage pipelines, industrial equipment, chemical transmission systems, energy power facilities, HVAC ventilation pipes and wastewater treatment devices.
