Water pipe (PFP) key technology
1.Inner coating pretreatment technology
- It is the first in Korea to chemically treat the inside and treat the phosphate film to completely remove oil and other foreign matter on the surface Increased adhesion
2. modified polyethylene technology
- Improved durability and hygiene by using modified polyethylene
3. Exterior multiple coating film forming technology
- Application of epoxy primer with excellent adhesion to steel pipe surface
- Adhesion is excellent and soft primary PE film is applied in the middle
- Application of a durable secondary hard PE film to the outermost side of 2.5mm or more
4. Expansion socket forming technology
- Socket connection method implemented in coated steel pipe (the first in the world)
- Simplify the shape of complex joints that can only be made by casting.
- Single squeeze to form socket part and rubber ring contact part
- Stiffness of machining part expanded by cold working
- secondary expansion projection
