SSAW steel pipe is a spiral seam steel pipe that is made of strip steel coils as raw materials, extruded at regular temperatures, and then welded through automatic double-wire double-sided submerged arc welding technology.
SSAW steel pipe is an important pipeline product, which is divided into ordinary spiral steel pipe and thick-walled spiral steel pipe. Thick-walled spiral steel pipes have some advantages over ordinary-walled spiral steel pipes:
High compressive strength: Due to the larger wall thickness of thick-walled spiral steel pipes, they have higher compressive strength and are suitable for withstanding greater pressure environments.
High impact strength: Thick-walled spiral steel pipes have better impact resistance due to their larger wall thickness when subjected to impact or external force.
High safety performance: Due to its high pressure resistance and impact resistance, thick-walled spiral steel pipes are safer and more reliable during use.
Long service life: Due to its high compressive strength and good impact resistance, thick-walled spiral steel pipes have a longer service life and can undertake engineering tasks longer.
In addition, SSAW steel pipe have higher strength than straight seam welded pipes, and can use narrower billets to produce larger diameter welded pipes, or use billets of the same width to produce welded pipes of different diameters. The nominal diameter of SSAW spiral welded pipe refers to its average outer diameter. This is because the pipe wall of the metal pipe is thin and the outer diameter of the pipe is not much different from the inner diameter of the pipe. Therefore, the average diameter of the outer diameter and the inner diameter is used to express the pipe diameter. These characteristics make SSAW spiral welded pipes have broad application prospects in various engineering projects.
In general, spiral submerged arc welding has important application value in the fields of petroleum, natural gas, water conservancy, thermal power and ocean engineering. Its welding process can meet special requirements such as long distance, high pressure, corrosion resistance, etc., and provides pipelines in these fields. Construction provides reliable technical support. With the continuous development and increasing demand in these fields, the application scope of spiral submerged arc welding technology will also be further expanded.
