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
