Galvanized steel pipe

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).
