Message:Galvanized steel pipe(galvanized pipe), Galvanised steel pipe(galvanised pipe) Galvanized steel pipes are made of steel that has been covered with a layer of zinc metal. During the galvanizing process, we immerse the steel in a molten zinc bath, ensuring a tough, uniform barrier coating. Application: 1.Building and structural material 2.Mechanical and general engineering purposes 3.Manufacturing of Bus Body, Railway Boogies 4.In Telephone department as Conduit Pipes Types: Galvanzied welded steel pipe, galvanzied seamless steel pipe Materials: Carbon steel Connection type: threaded Size range:1/8"-36" Schedule: sch40, sch80, sch120, sch160, XH, XXH Length of the galvanized tubes in diameter 4 - 16 mm 6000 + 100 mm in diameter 18 - 42 mm 6000 + 50 mm Tolerances of the zinc coated tubes - tolerances of the outside diameter: diameter between 4 - 30 mm ±0,08 mm diameter between 35 - 38 mm ±0,15 mm diameter up to 42 mm ±0,20 mm - tolerances of the inside diameter are according to EN 10305-4 - tolerance of the wall thickness ± 10% The Steel grades for the zinc coated tubes E 235+N and E 355+N Surface condition of the galvanized tubes First layer – electrolitically leached zinc (Zn) – acts as anode and in a corrosive environment it corrodes first and the base metal is cathodically protected against corrosion. The zinc layer thickness may be in the range of 5 to 30 micrometers (µm).
