Why Welding steel tube?

Welding steel tube is one pipe the surface has the steel pipe joint,which is use the steel belt or steel plate material through the bending deformation into round ,square ect then welded into shape.
The tube is manufactured without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.
Welded steel tube products are widely used in boilers, automobiles, ship building lightweight structural steel of the doors and windows, furniture, agricultural machinery, scaffolding, wire conduit, top shelves, containers, etc.. which can meet customer requirements, the special specifications welded pipe can be processed according to user requirements. Welded pipes for conveying water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses.
According to different welding methods can be divided into electric arc welding tube, the high frequency or low frequency electric resistance welded pipe and gas welding tube, furnace welding pipe , bondi pipe, etc.

ERW: Electric Resistance Welded steel tube used in oil drilling and machinery manufacturing, etc.
Furnace tube welding pipe can be used for water gas pipe, etc .

LSAW: Longitudinal Submerge-arc Welded used for high pressure straight oil and gas transportation etc.

SSAW: Spiral welded pipe used for the oil and gas transmission, and pipe pile etc.
Pipe Coating: HDPE/ 3PE/ 3PP/ Pipe cement mortar lining
Mill Test Certificate: EN 10204/3.1B 
Third party inspection: SGS, BV, Lloyds etc.
