552. Products description. ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24 OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a ERW Steel Pipes:ERW steel pipesERW pipes means Electric Resistance Welded Pipes. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usully for for high diameter. (cheapest process avaiable) ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes
erw vs lsaw pipe. ERW is - high frequency resistance attachment - straight seam welded pipe;LSAV is - submerged arc welding - straight seam welded pipe;Both belong to the straight seam welded pipe, however the 2 attachment method is totally different, the utilization is totally different, thus it can't represent the straight seam welded pipe alone.SSAW- spiral attachment - pipe is a lot of common.

Uses of SSAW Steel Pipe for fluid sevice for low pressure fluid service for pipelines for low pressure fluid service for pressure purposes for pipe piles Cold formed welded structural hollow sections of non-alloy and fine grain steels for pipeline transportation system of petroleum and natural gas industries(Class A steel pipe) SSAW Steel Pipe-SSAW Steel PipeThe annual yield of SSAW pipe with outside diameter 219mm-3620mm, wall thickness 5-25.4mm and steel grade B-X80 is 1,000,000 tons. its two steel pipe production lines, one for spiral submerged arc welded (SAW) steel pipe and one for longitudinal submerged arc welded (SAW) steel pipe, are respectively comprised of two sets of main machines and 1 set of sizing equipment. The annual output comes to 120,000 ton for spiral SAW pipe and 200,000 ton for longitudinal SAW pipe.
SSAW pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush. SSAW steel pipe - COSASTEELSY/T5037-2000 also known as the common fluid pipeline with spiral seam submerged arc welded steel pipe. Advantages of SSAW steel pipe. When the strip steel is fed into the spiral pipe welding machine, it will automatically become a spiral and be welded continuously, and the welded steel pipe will almost become an accurate circle.
Iron and steel as Hunan Standard Steel"s main business,manufacturing premium steel products and a high added value and fosters three major products categories, namely carbon steel,stainless steel and special steel.Specific products:carbon seamless steel pipe , erw steel pipe ,ssaw steel pipe,lsaw steel pipe,casing,tubing,drill pipe,hollow Welding Characteristics and Welding Technology of Jun 29, 2020 · Jun. 29, 2020. Share. Galvanized Steel Pipe is widely used in various industries. The advantage of using a galvanized steel pipe is to use metal zinc that can form a dense oxide protective layer in the air to protect the internal steel structure. In the case of welding or scratching, due to the presence of the Zn-Fe primary battery, the relatively active galvanized part can be used as a sacrificial anode to delay the corrosion of steel
