Welded steel pipes come in various types, each designed for specific applications and requirements. Here are some common types of welded steel pipes:

ERW (Electric Resistance Welded) Pipes:

ERW tubes are manufactured by rolling metal sheets and then welding the seam longitudinally using electric resistance. These carbon pipes are widely used in various applications, including oil and gas transportation, structural and mechanical applications, and fencing.

LSAW (Longitudinal Submerged Arc Welding) Pipes:

LSAW steel pipes are produced by bending and shaping steel plates and then welding them along the longitudinal seam using submerged arc welding. They are commonly used for conveying large-diameter and high-strength pipes in oil and gas pipelines and other infrastructure projects.

SSAW (Spiral Submerged Arc Welding) Pipes:

SSAW pipes are manufactured by spirally welding steel coils around a cylindrical form. They are suitable for use in high-pressure applications, such as oil and gas pipelines, and can accommodate various pipe diameters. The spiral welding process provides added strength and flexibility.

HFW (High-Frequency Welding) Pipes:

HFW pipes are produced using high-frequency welding of steel coils. This method creates a weld seam that is heated and fused under high-frequency currents. HFW pipes are commonly used in oil and gas pipelines, as well as in structural applications.

DSAW (Double Submerged Arc Welded) Pipes:

DSAW pipes are similar to LSAW pipes but involve welding on both the inner and outer surfaces of the pipe. This process results in a strong, dense weld and is often used in the construction of large-diameter pipes for water transmission and infrastructure projects.

Cold-Formed Welded Structural Hollow Sections:

Cold-formed welded structural hollow sections refer to pipes that are cold-formed from steel sheets or coils and then longitudinally welded. These pipes are commonly used in construction and structural applications.

Square and Rectangular Welded Steel Pipes:

These pipes are specifically shaped as squares or rectangles and are welded at the seams. They find applications in structural framing, construction, and various architectural uses.

Precision Welded Pipes:

Precision welded pipes are manufactured with high precision and tight tolerances. They are often used in industries where accuracy and smooth surface finish are crucial, such as automotive and machinery manufacturing.

The choice of the welded steel pipe type depends on factors such as the application, required strength, diameter, and the conditions under which the pipes will be used. Each type has its advantages and is suitable for specific purposes in industries ranging from construction and infrastructure to oil and gas.
