Description

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.   Application Fields of Plastic Lined Pipe: 1. It can be widely used in the system of media transportation and pro-environment treatment in Chemical industry, power plant, metallurgy, food industry etc. 2. It can be used on the project for drinking and water supply and sewerage works.   Working Conditions of Plastic Lined Pipe: Vacuum values(negative pressure): DN*5~DN*0:≤*0kPa DN***-DN**0:≤*0KPa ≥DN**0:≤*5KPa Positive pressure: DN**-DN*0:≤6.4MPa DN***-DN**0:≤6.4MPa ≥DN**0:≤2.5MPa   TemperatureRangeof Plastic Lined Pipe: 1. Media Temperature Range for PP lined pipe(GSF.PP): **0℃～**5℃ 2. Media Temperature Range for PVC lined pipe(GSF.PVC): **5℃～*5℃ 3. Media Temperature Range for PE lined pipe(GSF.PE): **0℃～*0℃ 4. Media Temperature Range for PO lined pipe(GSF.PO): **5℃～**0℃ 5. Media Temperature Range for PTFE lined pipe(GSF.F4): ***0℃～**0℃

 Attention:



1. The inner diameter below *5mm will be made ***0mm bigger than the original design in order to meet the requirement when the pipes are lined plastic;

 
 

2. Elbow, Tee, Cross Tee, Reducer can be customized or made by our factory as per the standard of《Anticorrosive pipeline design and manufacture and acceptance of the technical provisions.
