Black Carbon Steel Welded Square Galvanized Steel Pipe Size
size: OD:10*20-300*500mm, Dia:0.5-20mm,
Length:3-12m
Product Description
Black Carbon Steel Welded Square Galvanized Steel Pipe Size
Characteristics:
The pipe internal stress is very small and uniformly distributed after the full- length expansion. The corrosion and cracking of the pipe owing to stress can be effectively prevented. The application of welding on site is very easy because of the high dimension precision;
The inside and outside welding are performed after the tack welding , so the welding process is very stable with good weld quality;

Application:
The pipes are mainly used as long distance transportation pipeline for oil, gas, liquid coal etc. on land and
offshore. And also can be applied as construction pipes on offshore platform, power station, petrochemistry and city
construction etc.

Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.Black Carbon Steel Welded Square Galvanized Steel Pipe Size has been used used for water-supply pipes or as a strong tubing for outdoor applications.
USHDJ
Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. Black Carbon Steel Welded Square Galvanized Steel Pipe Size is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.Black Carbon Steel Welded Square Galvanized Steel Pipe Size is covered with a zinc material to make the steel pipe more resistant to corrosion.
