Main technology of water pipe (PFP)
For the first time in Korea, chemical treatment and phosphate film treatment are performed on the inside to completely remove oil and other foreign substances on the surface to increase adhesion.
-Improved durability and hygiene by using modified polyethylene
-Epoxy primer with excellent adhesion to the steel pipe surface
-Coated with excellent adhesion and soft primary PE film in the middle
-Applying more than 2.5mm of durable and hard secondary PE film on the outermost surface
-Realization of socket connection method on coated steel pipe (first in the world)
-The complex shape of the connection, which was only possible with casting, was simply realized through the expansion process.
-Formation of socket part and rubber ring contact part by one time expansion
-2nd expansion protrusion
