Nine categories for welded pipes by manufacturing process
Welded pipe, one pipe the surface has the steel pipe joint, is now widely used in conveying water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. As for ERW steel pipe, it is only one category of welded pipe. So that we can have a view for the categories of Nine category.
ERW steel pipe:A kind of pipe rolled to become a pipe and welded using Electric Resistance Welding process.
(SSAW) Spiral submerged-arc welding steel pipe: its forward direction and forming pipe has reel molding angle (adjustable), side molding edge welding and weld them into a spiral.
(SAW) Submerged arc welding pipe: a common arc welding process.
(HFI) High frequency welded pipe: this is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.
(LSAW) Long-Submerge-arc Welded: leaflets plate as raw material, the steel pipe in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
(EFW) Electric Fusion Welded Pipe: The EFW pipe division consists of a JCO forming press, helical / spiral mill, inside and outside welding system, heat treatment furnace and testing facilities.
(DSAW) Double Submerged Arc Welded: it is available in straight and spiral welded formats and used in a variety of applications.
(UOE) Uing and Oing forming pipe: the formed pipes are welded inside by five internal welding stations with three wires for each weld, and welded outside by four external welding stations with three wires for each weld.
(JCOE) J-ing, C-ing and O-ing: process with characteristics of high forming accuracy and efficiency as well as balanced distribution of forming stress.
The steel pipe above can be supplied by Tianjin Xinyue Steel Group.
