PE lined plastic pipe
Performance: Medium working temperature: -25℃~+75℃ (modified polyethylene working temperature is 105℃)
Medium working pressure: positive pressure 2.5MPa, negative pressure 75KPa at room temperature
Corrosion resistance: good corrosion resistance to non-oxidizing acids (such as hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dilute nitric acid, alkali and salt solutions, but not resistant to corrosion by concentrated nitric acid, concentrated sulfuric acid and other strong oxidants . Generally good corrosion resistance to organic solvents and normal temperature.
Typical application: suitable for the transportation of general corrosive liquid media, and more suitable for the transportation of domestic water and drinking hot and cold water. When the water is delivered, it does not affect the water quality and meets the requirements of food hygiene. The high wear resistance and high density polyethylene pipe can be widely used Transportation of solid-liquid slurry such as coal and ore. It is widely used in industries such as petrochemical products, electricity, tap water, and environmental protection.
PP lined plastic pipe
Performance: Medium working temperature: -25℃~+110℃
Medium working pressure: positive pressure 2.5MPa, negative pressure 94KPa at room temperature
Typical application: suitable for the transportation of corrosive fluid media and industrial pure water, chemical pure water, ionized water, and non-ionized water. The service life is longer than stainless steel. It can replace stainless steel pipes and has a longer service life than rubber-lined pipes and glass steel pipes.
Corrosion resistance: In addition to strong oxidizing acids such as concentrated nitric acid, fuming sulfuric acid, and chlorosulfonic acid, it can withstand most organic and inorganic acids, alkalis, and salts. It has good stress corrosion resistance and can withstand nitric acid below 10% , Formic acid, acetic acid, hydrochloric acid below 36%, hydrobromic acid below 20%, dilute hydrofluoric acid, various concentrations of carbonic acid, boric acid, butyric acid, alkali and most salts, mercury, air, NH3, CO2 Corrosion of CO, NO2, HCL and other gases is multi-functional.
