Q235B 12 inch diameter ERW tube Electric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. SSAW Pipe - Spiral Submerged Arc Welded PipeQ235B spiral steel pipe details:Q235B spiral steel pipe is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double-wire double-sided submerged ar. LARGE-DIAMETER PIPES/LINE PIPES The LONGTAIDI Group is one of the largest global suppliers of large-diameter pipes for oil- and gas pipelines.
The spiral steel will send the strip steel to the welded unit, and the strip steel will gradually roll up after rolling by multiple rollers to form a circular tube blank with an opening gap. Adjust the reduction of the extrusion roller so that the gap between the welds is controlled at 1-3mm and the two ends of the welded SSAW Steel Pipe,ERW Steel Pipe,Carbon Steel Pipe,Spiral Large Welded Steel Pipe 3. 54inch*9.52Spiral steel pipe are producing 4. 36 inch Spiral Submerged-Arc Weld steel pipe (4) 5. 457mm OD LSAW steel pipe stuffed into Containers Tianjin Zhongshun Petroleum Steel Pipe Co.. is a specalized manufacture of petroleum steel pipe, founded in 1995.It is located in the steel Base,Daqiuzhuang Town which

The Characteristics of Straight and Spiral Seam Welding for Large Diameter Steel Pipe Date:2019-06-05 keywords:characteristics, straight, spiral, seam, welding, steel, pipes Straight seam welding of large diameter steel pipes is produced from steel plates, while spiral welding of large diameter steel pipes is produced by hot rolled coils. What is Welded Pipe? - Zhangzhou Steel PipesLongitudinal Welded Pipes; The Difference Between Spiral & Longitudinal Welded Pipes. Spiral welded pipes the weld or seam in these pipes is in the form of a spiral. The sheets are formed into a spiral using submerged arc welding process. Spiral steel pipes are known as SSAW pipes (submerged arc welded pipes). They have large-diameter in size.
Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89 standard. What is a spiral steel pipe? - ugsteelmillThe most common way to connect large diameter spiral steel pipe is to weld, but in some projects, it is often used in the form of screw connection, flange connection, socket connection and groove connection. Welding and flange connection. Connection features Welding, flange connection belongs to l spiral steel pipe traditional pipe connection, in safety, sealing performance, cost of space, the
