Welded pipes are made up of a hot-rolled coiled steel strip that is then rolled into a cylindrical shape. The seam is then welded. Welded pipes are also made by electric welding (Longitudinal Seam Welded or Spiral Welded Pipes).
Seamless pipes are long steel tubes with no welding or joints and are manufactured from solid round billets which is then cut into appropriate lengths.
Welded tube is less expensive than seamless pipes and is readily available in big diameter pipes and long lengths.
What is the difference between SAW welding and MIG welding?
Submerged Arc Welding is a process that is typically done on metals that have a high iron content level. It’s considered a relatively simple welding process due to its ability to be used as either an automatic or semi-automatic process.
We use Lincoln Electric IDEALARC® DC-1500 ELECTRIC WELDER to produce spiral welded pipes (SSAW).
The DC-1500 is designed for submerged arc welded that produces outstanding welding performance with a single range full output control potentiometer.
Welded Pipes Applications
Welded steel pipes applications have evolved and grown more complex, the steel pipe industries and pipe manufacturers that serve them have had to keep pace.
Welded steel pipe common market in general are: double submerged arc welded pipe (DSAW), high-frequency welded pipe (HFW pipe), and the spiral submerged arc welded pipe (SSAW).
The spiral submerged arc welded pipes (SSAW) are now adding significant momentum to global growth. These pipes are usually are in large diameters forms and mostly used as long-distance pipelines.
