Structural welded steel pipe usually use carbon steel as main material, the kind of that usually includes LSAW steel pipe, ERW steel pipe, and spiral welded pipe. Prime Steel Pipe as an excellent pipe manufacturer that has over 20 year experience to produce ERW steel pipe and spiral welded pipe with high-quality, welcome you to inquiry us without any hesitation. Structural welded steel pipe is usually applied in in welded steel pipe, steel structure bridge support, building structural tube, pipe pile foundation, etc.. As the structural tube needs great egret capacity to pressure-bearing and withstand voltage, generally, we use the pipe that the wall thickness is greater than 8mm. Structural welded steel pipe is made with double-sided submerged arc welding or high-frequency welding. The main parameters of the structural welded steel pipe include diameter, wall thickness, length, welding technology, whether the need for surface corrosion insulation treatment. The welded steel pipe for exporting needs to be grooved, painted, added the cap.


Structural welded steel pipe is manufactured by continuous on-line production. According to the welding technology section structural welded steel pipe is divided into automatic welding, manual welding, automatic welding commonly used submerged arc welding, plasma welding; manual welding general use of argon arc welding. The process of the product determines its advantages and disadvantages. General welded steel pipe has high precision and uniform wall thickness, and the surface brightness of the pipe is high (surface grade of steel pipe determines the brightness of pipes). Therefore, it reflects its economy and aesthetics in the high-precision, low-pressure fluid applications. What's more, the thicker the wall thickness is, the greater the unit and welding equipment investment is, the structural welded steel pipe has more no economical and practical. The wall thickness is thinner, its input-output ratio will decrease accordingly.
