PVC－U
Pipes for Chemical Industry
 ◆Corrosion
proof,non-encrustation
◆Little
resistance of liquid,high efficiency
of transmission
◆Light
weight,convenient for installation and
maintenance,reliable property
◆High endurance
of pressure,good property of sealing
◆Long using
life and can reach 50 years in normal
use.
◆Transfer
chemical corrosive chemical liquid
◆Release
Industry and mining enterprises corrosive
gas
◆Transfer
pressure fluid,such as non-drinkable
water and so on
