Four ball lined PTFE expansion joint

[source: unknown] [date: 2020-08-15 15:59] [heat: ]
Four ball lined PTFE rubber expansion joint is also called lined PTFE rubber joint, rubber flexible joint, rubber expansion joint, rubber flexible connection. The product is a kind of rubber connector, which is a hollow rubber product used for flexible connection between metal pipes. Fluorine lining is mainly used in strong corrosion conditions, lining fluoroplastics (commonly used PTFE, nylon, etc.) where metal pressure vessels (valves, tanks, etc.) or rubber products (rubber expansion joints, compensators, etc.) need to contact with strong corrosion, so as to prevent medium corrosion of pressure vessels.
The inner lining of the PTFE lined expansion joint is white, and the outer side is a black rubber ball. It is made by the new technology of air blowing die, which is composed of the inner rubber layer, the reinforcing layer, the middle rubber layer and the outer rubber layer, and the loose sleeve forging low carbon steel flange. The PTFE lined expansion joint has the characteristics of high pressure resistance, good elasticity, large displacement, good vibration and noise reduction effect, convenient installation, and can compensate for the thermal expansion and cold contraction caused by temperature change. In addition, it also has good acid-base resistance and stable chemical state, which can greatly reduce the corrosion effect of corrosive medium on rubber expansion joint. It is suitable for all kinds of medium expansion joint.
The PTFE lined expansion joint has the characteristics of vibration reduction, high temperature resistance, flexibility and friction resistance. It is suitable for the connection of pipeline dislocation difference, displacement, size change and vibration parts. It can be used as feeding and discharging pipe of storage tank, tank car and other equipment, as well as other special uses. It is widely used and has a comprehensive effect. In addition to sodium fluoride and other chemicals, it has excellent resistance to alkali and alkali, and is not suitable for all kinds of chemicals. Sealing, high lubrication and non stickiness, electrical insulation and good anti-aging endurance, excellent temperature resistance (long-term operation at + 250 ℃ to - 180 ℃).
Gongyi Yuanda water supply materials Co., Ltd. is engaged in the research and development of waterproof casing, rubber joint, expansion joint, force transfer joint, expansion joint, compensator, duckbill valve, with advanced manufacturing technology, exquisite processing technology, high quality products and timely supply.
