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.
The steel pipe above can be supplied by Threewaysteel pipe company. And among these five categories, we would like to have a rank from ERW steel pipe, SSAW steel pipe, to LSAW steel pipe.
