Introduction: The corrosion resistance of the rubber joint used in the chemical pipe joint is often reduced due to the use of the rubber joint in the chemical industry.

PTFE lining Rubber joint In the previous application of rubber joint, because of the entry of some corrosive media, the rubber joint can not resist corrosion, and the use performance has reduced the performance of rubber joint. Because rubber, glass, metal aluminum alloy and other materials have shortcomings in corrosion resistance, they can not meet the harsh conditions of temperature, pressure, chemical media coexistence of the natural environment, resulting in the damage is very shocking. The corrosion resistance of PTFE material has become the key corrosion resistant material in crude oil, chemical industry, textile and other industries. Its practical application includes: conveying pipeline, exhaust pipe and pipeline for conveying corrosive vapor, hydraulic oil pipe of rolling mill, high and low pressure pipeline of airport hydraulic system and cold pressing system, rectification tower, heat exchanger, lining of kettle, tower and tank, gate valve and other chemical equipment.
The key application of PTFE lined joint is in the medium pipeline with strong acid, strong alkali and strong high temperature. Its characteristics are better than that of ordinary acid-base rubber joint. The characteristic of tetrafluoroethylene is that it can bear negative pressure slightly. Compared with fluororubber joint, the cost of PTFE lined joint is relatively low and it is very easy to be accepted by customers. Most customers who need strong acid and alkali resistant rubber joint can be considered Requirements.
PTFE lining Flexible rubber joint The ptfe.teflon PTFE coating is added to the general rubber joint or EPDM super wear-resistant rubber joint. The key coating is milky white, which can reasonably protect the rubber joint from corrosion by corrosive medium, such as strong acid, strong alkali or high temperature fuel. The PTFE coating can reasonably adhere to the upper edge of the pipe cavity to avoid medium erosion or pipeline pulling The application for closing up causes getting rid of. Ptfe.teflon material is a chemical product with high purity and no residue. It increases the adhesion of the coating and makes the product have excellent corrosion resistance and impact resistance. The coating is non-toxic, solvent-free, no exudate, does not affect the medium. It is more suitable for pharmaceutical industry, beverage, food, brewing, chemical industry, electric power industry and desulfurization industry with high hygienic conditions.
The PTFE lined joint is divided into 0.25MPa, 0.6MPa, 1.0MPa, 1.6Mpa and 2.5MPa according to the pressure level.
Performance characteristics of PTFE lined joint:
1. Small size, light weight, good elasticity, convenient installation and maintenance.
2. After installation, it can absorb the transverse, radial and angular displacement caused by pipeline vibration; it will not be limited by the pipe misalignment and flange non-linear surface.
3. After installation, it can reduce the noise caused by the vibration of pipeline water pump, and has strong vibration absorption capacity.
