Mechanical properties of seamless pipes

Strict product inspection

Each steel pipe must pass the inspection layer by layer. Only the products that pass the inspection can leave the factory. Never let an unqualified product flow into the market

Seamless steel pipe coating:

3PE	3PP	FBE Coating	Epoxy Coating
Special Painting	Galvanization	Oiling	Painting
Bare	Galvanized aluminum magnesium	anticorrosive

Black seamless pipe production cycle:
