PTFE-lined Composite Pipe

Product performance:

Temperature:-15℃~+80℃( highest working temperature of modified polyethylene:+105℃)
Pressure: positive pressure +2.5Mpa,negative pressure at normal temperature:75Kpa
Corrosion resistance:Teflon composite steel pipe can resist almost all chemical media(including concentrated nitric acid and aqua regia) in addition to molten metal lithium, potassium, sodium, chlorine trifluoride,OF3 under high temperature, liquid fluorine with high flow.It can work at the temperature of 230℃-250℃ for a long time.PVDF or other composite steel pipes all have a good resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali.But they are not resistant to fuming sulfuric acid, hot concentrated sulfuric acid and nitric acid, over 90 ℃ ketone, ester, amine and sulfonation agent with high temperature.


Product Characteristics:

1.High Temperature Resistance--operating temperature is 250℃
2.Low Temperature Resistance--good mechanical toughness.Even if the temperature drops to -196℃, 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


Production range:

1.nominal diameter:DN20mm—DN1200mm(Large-diameter pipe can reach 4m).
2.All kinds of non - standard elbows,tees and reducings.
3.Can be prefabricated according to user requirements.
