Spiral steel pipe connection skills
Spiral steel pipes, or SSAW steel pipes, are welded pipes made from strip steel coils as raw materials, which are extruded at a regular temperature and welded using an automatic double-wire, double-sided submerged arc welding process. The quality of the joint in SSAW pipes directly affects the strength and sealing performance of the connection. Here are some essential operational tips and key considerations for ensuring seamless, misalignment-free joints.

Details of SSAW steel pipe for drainage application
The drainpipe typically uses SSAW (Spiral Submerged Arc Welded) steel pipe, which is manufactured using the submerged arc welding method. The spiral weld creates a continuous seam, which helps distribute the pressure from the liquid inside the pipe evenly across the pipe's surface, enhancing the strength of the SSAW steel pipe. In contrast, if straight seam steel pipes (such as ERW pipes) were used, larger steel plates would be required to form the pipe, complicating the manufacturing process and increasing costs.

Advantages of LSAW steel pipe JCOE forming
The JCOE process is one of the key forming techniques used in the production of straight seam steel pipes. It involves several steps such as bending, jointing, internal welding, external welding, straightening, and flattening. These processes ensure that the final product meets the relevant industry standards. The steel pipe's inner and outer surfaces must be smooth, free from defects such as folding, cracks, delamination, lap welding, arc breakage, or burn-through. Any local defects with a depth exceeding the lower wall thickness deviation are not allowed, though minor defects within acceptable limits are permissible.

Pre-welding technology of LSAW steel pipe
LSAW (Longitudinal Submerged Arc Welded) steel pipes are produced by rolling a single medium or thick steel plate into a cylindrical shape using a mold or forming machine, followed by double-sided submerged arc welding. This process not only joins the edges of the plate but also expands the pipe diameter. One critical aspect of the LSAW steel pipe production process is the pre-welding stage, where the forming seam is subjected to "shallow welding" along the entire length of the pipe. This specialized technique is essential to ensure the integrity of the final welded pipe.

Cold crack for ERW steel pipe
Cold cracks are a type of defect that may occur in Electric Resistance Welded (ERW) steel pipes during or after the welding process. These cracks are a significant quality concern as they can compromise the structural integrity and reliability of the pipe.
