Separable type

teflon（F4)

It is a kind of plastic with stable chemical properties. It is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as strong alkali and various organic solvents. It is not resistant to the corrosion of chlorine trifluoride, high temperature chlorine trifluoride, high flow rate liquid fluorine, liquid oxygen and self oxygen.

1、浓酸、碱等强腐蚀性介质。
2、卫生类介质。

Perfluoroethylene propylene（F46)

The wear resistance and negative pressure resistance of F4 are higher than that of F4.

同上

Polyfluoroethylene（Fs)

The upper limit of applicable temperature is lower than that of polytetrafluoroethylene, but the cost is also lower.

80℃

Polychloroprene rubber

1. It has excellent elasticity, high breaking force and good wear resistance.

2. It is resistant to corrosion of low concentration acid, alkali and salt medium, but not to oxidation medium.

stainless steel 0Crl8Nil2M02Ti

It is suitable for industrial water, domestic water, sewage and other weakly corrosive media. It is suitable for petroleum, chemical, steel and other industrial sectors and municipal, environmental protection and other fields.

Hastelloy B

It has good corrosion resistance to all concentrations of hydrochloric acid below boiling point, as well as non chlorinated acid, alkali and non oxidizing salt solution such as sulfuric acid, phosphoric acid, hydrofluoric acid and organic acid.

Hastelloy C

It can resist the corrosion of non oxidizing acid, such as nitric acid, mixed acid, or mixed medium of chromic acid and sulfuric acid, as well as the corrosion of oxidizing salts such as FC +, Cu + or containing other oxidants, such as hypochlorite solution higher than normal temperature and seawater corrosion

tantalum

It can resist the corrosion of seawater, various chlorides and hypochlorites, oxidizing acids (including fuming sulfuric acid), organic acids and alkalis. It is not resistant to the corrosion of pure reducing acid (such as sulfuric acid and hydrochloric acid), but if the acid contains oxidants (such as nitric acid, FC +, Cu +), the corrosion is greatly reduced.

tantalum

It has excellent corrosion resistance and is similar to glass. In addition to hydrofluoric acid, fuming sulfuric acid and alkali, it can almost resist the corrosion of a chemical medium (including hydrochloric acid with boiling point, nitric acid and sulfuric acid below 150 ℃). In alkali; corrosion resistant.

Platinum / titanium alloy

It is resistant to almost all chemical media, but not suitable for aqua regia and ammonium salts.

Stainless steel coated with tungsten carbide

It is used for non corrosive and strong wear medium.

Note: due to the variety of media, and its corrosivity is affected by complex factors such as temperature, concentration, flow rate, etc., this table is only for reference. Users should make their own choice according to the actual situation. If necessary, the corrosion resistance test of the materials to be selected, such as coupon test, should be carried out.
