Short pipe line F4

Features/Benefits for pipe lined F4:
-Solid PTFE resists virtually all chemicals
-High and low temperature capability
-Good for ultra-pure reagents and solvents

Application Fields of Plastic Lined Pipe:
1. Widely used in the system of media transportation, PRO-environment treatment in Chemical industry, power plant, metallurgy, and food industry etc.
2. Widely used in the transportation system of petroleum and nature gas.
2. Widely used on the project for drinking and water supply and sewerage works.
4. Widely used for pipes of ship project, equipment and the anti-corrosion of sanitation
The Characteristics of Plastic Lined Pipe:
1. Excellent physical properties;
2. Good anti-corrosion;
3. Same mechanical strength with steel pipe;
4. Sanitary, non-toxic, non-fouling and non-breeding;
5. Resistance to chemical corrosion, marine bio-corrosion, and resistance to cathodic stripping;
6. Skilled and convenient Installation process;
7. Good weather resistance, and adapt to the severe environment of desert, saline aquifers and so on;
8. Smooth inside wall, high efficient transportation and long life-span.


Made from pure PTFE, this material can be used to handle virtually all corrosive media, including hydrofluoric acid, nitric acid, sulfuric acid and alkalis. It is ideally suited for custom packaged products requiring the ultimate in chemical resistance.
