SSAW and LSAW Steel Pipe

As the spiral welded pipe steel coil rolling direction is not perpendicular to the axial direction (which depends on the solution folder steel helix angle), straight seam steel pipe steel pipe rolling direction is perpendicular to the axial direction, therefore, spiral welded pipe crack resistance of materials is better than the straight pipe joints.

Comparison of Characteristics Between ERW Steel Pipe and Spiral Submerged Arc Welded Steel Pipe

Both straight seam resistance welded steel pipes (ERW) and spiral submerged arc welded steel pipes (SSAW) can better meet the requirements of oil and gas pipelines. For medium-diameter ($630mm) steel pipes, ERW steel pipes are mostly used abroad. Spiral submerged arc welded pipes are generally only used for low-pressure fluid transmission, civil buildings, structures and piling pipes.

The Difference Between Seamless Pipe And Welded Pipe

Steel pipe is a kind of hollow long steel, which is used as a pipe for conveying fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used. Used in the manufacture of mechanical parts and engineering structures. Also used to produce a variety of conventional weapons, barrels, shells and so on.

Straight Seam Steel Pipe Common Problems and Preventing Measures

Straight seam steel pipe is steel or steel after bending molding, and then made by welding. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. The special welder then welds a seam. Outer weld brightly polished. The inner pipe of the general burr does not hit.
