PTFE extruded tube - tight lining type: It is small anti vacuum, suitable for diameters less than 300mm. PTFE adhesive -type: It is anti -corrosion, anti-infiltration, allowable low pressure and low temperature, that is suitable for large tank. ETFE, PO Rotational Lining: It is allowable variable structure that is the overall seamless and suitable for diameters less than 6000mm.
The steel pipes/tubes are lined in PTFE, ETFE or PO. They are used to anti-corrosion in acid or alkali medium as the washing column, absorption column, distillation column and extraction column. The packed column is simple at structure. It is used widely in chemical industry.
PTFE Lined steel pipes/tubes
1.High Temperature Resistance--operating temperature is 250ºC
2.Low Temperature Resistance--good mechanical toughness.Even if the temperature drops to -196ºC, it can also keep the elongation at 5%.
3.Corrosion Resistance--For the majority of chemicals and solvents,it shows inertia. Resistance to strong acid,strong alkali, water and all kinds of organic solvents.
4.Weather Resistance--best aging life of plastic
5.High Lubricating Property--the lowest friction coefficient in solid materials
6.Inadhesion-- the minimum surface tension in solid materials, and does not adhere to any material
7.Nonhazardous--no biological toxicity
