The inner wall types of rubber industrial hoses
Joints are commonly and widely used in pipe and hose systems in many industries such as petroleum, chemical, textile and others. This time I will introduce Teflon lined joint. How much do you know about it?
What is Teflon lined joint?
Teflon lined joint is based on normal rubber joint or high abrasion resistance EPDM rubber joint, then add a Teflon coat which is mainly white.
What are the characteristics of Teflon lined joint?
- Teflon is a kind of chemical products, which has high purity. It can strengthen the adhesion of coating and then offer the products excellent corrosion and impact resistance.
- The coating has smooth surface, small friction coefficient, good non-adhesion performance and excellent foreign matter adhesion resistance.
- The coat is nontoxic without exudation and will not pollute the medium.
What are the advantages compared with normal joint?
The normal rubber joint has bad performance in resisting the corrosion from some mediums. Besides, rubber, glass and metal are detective in corrosion resistance and it is difficult for them to meet the harsh environment of temperature, pressure and chemical medium, so the lost is amazing. Because of the excellent property, Teflon coat can protect the rubber joint from corrosion like strong acid and alkali. It has excellent abrasion resistance in the meantime.
In another hand, the cost of Teflon lined joint is lower than it of fluororubber joint and it can meet the requirements of clients on acid and alkali resistance.
What’s the application of Teflon lined joint?
Because of the excellent corrosion resistance, Teflon lined joint has became the main corrosion resistant material in petroleum, chemical and textile industry. It can be used in the corrosive air transfer pipe, exhaust hose, high pressure oil hose, high and low pressure hose in airplane hydraulic system. It can be also used in distillation column, switch, valve and many other industrial equipment.
Besides, because it is nontoxic without polluting the medium, it can be used in industries with high requirements on health like pharmacy, food, beverage and medicine.
