Single ball lined PTFE rubber joint PTFE bellows
PTFE bellows is based on general rubber joint or EPDM high wear-resistant rubber joint with PTFE coating inside. The PTFE coating of PTFE bellows is mainly white, which can effectively protect the PTFE bellows from corrosive medium, such as strong acid, strong alkali or high-temperature oil, The original mechanical and physical properties of the PTFE bellows are not affected. PTFE bellows can still compensate the pipe vibration, absorb the pipe displacement and reduce the pipe noise.
PTFE bellows features
1. The PTFE bellows with polytetrafluoroethylene has high temperature resistance and can meet the service temperature range of - 60-200 ℃ under the condition of strong corrosive medium.
2. PTFE bellows can be used under vacuum.
3. The PTFE bellows is resistant to high pressure and can withstand working pressure up to 3Mpa in the temperature range.
4. Impermeability of PTFE bellows . The PTFE bellows adopts high-quality polytetrafluoroethylene resin lining, so that the product has excellent impermeability.
5. The integral molding and sintering process of PTFE bellows solves the problem of cold and heat expansion of rubber and fluorine to achieve synchronous expansion.
6. The PTFE bellows with PTFE is prepared with standardized size, especially for the pipeline of chemical pipeline. The pipe fittings have strong interchangeability, which provides great convenience for installation and spare parts.

Applications of PTFE bellows
The PTFE bellows has excellent chemical stability and corrosion resistance. PTFE bellows is one of the best corrosion resistant materials today. Except for molten metal sodium and liquid fluorine, PTFE bellows can resist all kinds of chemicals. PTFE bellows can not change when boiling in aqua regia. PTFE bellows is more common in chemical pipeline, mainly used in strong acid-base, strong high temperature, strong corrosion pipeline equipment, especially in corrosive medium. including: conveying pipe, exhaust pipe, steam pipe of corrosive gas, high-pressure oil pipe of rolling mill, heat exchanger, lining of tower and tank, valve and other chemical equipment.
