Steel Pipe ( Steel Tube )
Product Description :
Tianjin Rainbow steel pipes with hot dip coating or electric-galvanized coating on the surface of steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, not only as pipelines for water, gas, oil and other general low-pressure fluids, but also as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, tubes for coal distillation and washing oil exchangers in chemical coking equipment, and tubes for trestle pipe piles and support frames in mine tunnels.
We mainly produce square tube , round tube ,pregalvanized steel tube ,octagonal tube,hexagonal tube in different size and thickness. Customized product is also available to develop in our place. We also have our own hot dip galvanizing mill which had passed ISO 14000 . All the process can be done under our company control.
