Material

Character

Range of application

F-46 fluorinated ethylene-propylene

1. Chemical stability, resistance to almost all chemical media corrosion.

2. heat-resistant, long-term work at 180 ℃.

3. High mechanical strength, good wear resistance.

4. The inner surface is smooth, and is not easy to adhere to precipitate.

5. The inner lining with metal mesh, vacuum-resistant, anti-vacuum.

All fluid addition to strong wear medium such as mortar.

It can be used to medium has sanitary requirement such as drinks.

PO  polyolefin

1. Has good physical and chemical properties, is a more advanced anti-corrosion materials now.

2. Long-term using at 80 ℃.

3. Has good stress cracking resistance, better than rubber.

4. Has good impact resistance.

5. Has good rigidity.

All fluid in addition to gasoline, diesel and acetaldehyde, the temperature is not higher than 80 ℃.

PUR  polyurethane

Good wear resistance, isn’t resistant to corrosion,  operating temperature can not exceed 50 ℃

Mortar and other strong abrasive fluids

Material

Corrosion resistance

Hc hastelloy C

Anti-oxidizing acids such as nitric acid, chromic acid and sulfuric acid mixture. Also resistant to oxidizing salts or other oxidant-containing corrosive environment. Seawater, alkali solution, chloride solution with good corrosion resistance.

Hb  hastelloy B

Sulfuric acid, phosphoric acid, hydrofluoric acid and other non-oxidizing acid, alkali, salt, with good corrosion resistance.

Ta tantalum

Addition to hydrofluoric acid, it can resist almost all chemical media. Because of its price is so high, it is only used for hydrochloric acid and concentrated sulfuric acid.

316L stainless steel

It is used for weak corrosive medium such as industrial water, domestic water and waste water, neutral solution and weak acid such as carbonic acid and acetic acid.
