Decho is a professional supplier on din30670 3pe coated seamless steel pipe
Seamless Pipe with 3PE coating are widely used in buried pipeline , it has below advantages :
With strong sealing performance, it can save a lot of energy , reduce cost and protect environment under long-term operation .
With strong waterproof and corrosion resistance , the construction is easy and rapid .
It also has good corrosion resistance and impact resistance under low temperature conditions, and the water absorption rate of PE is low (less than 0.01%).
The service life can reach 30-50 years, and the correct installation and use can make the maintenance cost of the pipe network extremely low
At the same time, it has high epoxy strength, low PE water absorption and good hot melt adhesive flexibility. It has high corrosion protection reliability.
