The contract is a genuine scanned document provided only as proof of supply. It is not intended for other uses. Please do not reproduce or modify it. Thank you for your cooperation.
3.Introduction to the Use of PTFE-Lined Rubber Expansion Joints at Yichang CSG Silicon Material Factory:
This contract primarily involves the use of PTFE-lined rubber expansion joints with three different diameters: DN40, DN50, and DN65.
Firstly, what is a rubber joint? The Songjiang Group rubber joint is a tubular rubber component composed of inner and outer rubber layers, canvas layers, and steel wire rings. After vulcanization, it is combined with metal flanges or parallel joint loose sleeves. This product can reduce vibration and noise, and compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems.
So why is it called a PTFE-lined rubber joint? The PTFE-lined rubber joint has a layer of polytetrafluoroethylene (PTFE) material lined on the inner wall of the rubber joint. This lining of PTFE material inside the rubber joint contacts the pipeline medium, providing corrosion resistance, wear resistance, and other functions, without affecting the performance of the rubber joint itself.
Introduction to Polytetrafluoroethylene (PTFE): Weathering resistance: Resistance to irradiation and low permeability: Long-term exposure to the atmosphere, surface and performance remain unchanged. Non-flammability: Limiting oxygen index below 90. Acid and alkali resistance: Insoluble in strong acids, strong alkalis, and organic solvents (including magic acid, namely fluorosulfonic acid). Antioxidant: Resistant to corrosion of strong oxidants. Acid and alkali: Neutral.
