Polyethylene 3-Layer Coated Steel Pipes & Fittings
Product Features
- Polyethylene powder is firmly coated on the outside to improve coating power
- The 3-layered coating allows solid and reliable sequential welding
- Prevent coating layer formed on the outer surface from peeling off due to external impact during burial
- More effective, longer-lasting usability in surface technology with more reliable products
- It is possible to coat a small amount of various kinds of steel pipe regardless of the steel pipe or steel fittings shape while reducing the equipment cost
Models of Application
In order to protect the outer surface of a steel pipe that transports liquid, liquefied gas, water, etc. with a working temperature of 60 ℃ or less, the outer surface of the steel pipe is covered with 3-layers by powder welding to protect the outer impact and corrosion. To extend the life of the product.
- Coated steel pipes & fittings for water works
- Coated steel pipes & fittings for water services
- Agricultural&Industrial water
- Gas pipe and oil pipe
- Other buried steel pipes
