Scaffolding Tubes Bs1139 Galvanized Steel Pipe Carbon Steel Round
Pipe
Galvanized steel pipe is a welded steel pipe with a hot-dip or
electro-galvanized layer on the surface. Galvanizing can increase
the corrosion resistance of steel pipes and prolong their service
life. Galvanized pipes are widely used. In addition to being used
as pipeline pipes for general low-pressure fluids such as water,
gas, and oil, they are also used as oil well pipes and oil
pipelines in the petroleum industry, especially offshore oil
fields, and oil heaters and condensation pipes for chemical coking
equipment. Pipes for coolers, coal distillation washing oil
exchangers, trestle piles, and support pipes for mine tunnels, etc.
Galvanized steel pipe has the following production steps:
Black parts
inspection→hanging→degreasing→rinsing→pickling→cleaning→dipping
flux→hot air drying→hot-dip galvanizing→cooling→passivation and
rinsing→unloading→inspection, trimming→packaging, storage,
transportation .

Galvanzied Steel Pipe Type:
1. Pre-galvanized: Pre-galvanized steel pipe is directly processed
from hot-dip galvanized steel strip.
Galvanized layer: 40-60g/sm, if more galvanized layer is needed, it
can be processed according to order. (The thickness is 0.7mm-4.5mm)
2. Hot-dip galvanized: Hot-dip galvanized pipe has a thicker zinc
coating than pre-galvanized pipe. The black steel pipe will be
immersed in a zinc bath for galvanizing. The zinc coating can be:
200-500g/sm
Galvanized Round Steel Pipe Application area:
Galvanized pipe is mainly used for curtain wall, construction,
machinery manufacturing, shipbuilding, steel structure engineering,
solar energy Electric support, steel structure engineering, power
engineering, electric power, agriculture, chemical machinery, glass
curtain wall, car chassis, airport, etc.
Galvanized Round Steel Pipe Packing:
1,in bulk
2, in hexagonal bundles by steel strips only
3, in bundles by steel strips then packed by water-proof plastic
wraps
