Welded steel pipes can be produced using common welding methods:

  • Electric Resistance Welding (ERW): ERW involves passing an electric current through the edges of the steel plate or strip to generate heat.
  • Submerged Arc Welding (SAW): SAW is a welding process that involves the formation of an arc between a continuously fed electrode and the workpiece.
  • Gas Metal Arc Welding (GMAW) or Metal Inert Gas (MIG) Welding: GMAW, also known as MIG welding, uses a consumable electrode wire and a shielding gas to protect the weld pool from atmospheric gases.
  • High-Frequency Induction Welding (HFIW): HFIW is a welding technique where high-frequency electrical currents are induced in the steel pipe to create heat.

Differences Between Straight Seam Welded Pipes And Spiral Welded Pipes:

Construction:
Straight seam welded pipes are made by welding a long, continuous seam along the length of the pipe.

While, spiral welded pipes are made by helically winding a steel strip or plate and welding the edges together to form a continuous spiral seam.

Applications:
Straight seam welded pipes are commonly used in applications that require a high level of strength and are suitable for transporting fluids and gases under high pressure.

However, Spiral welded pipes are commonly used in applications that require larger diameters and are suitable for transporting fluids, gases, and solid materials.
