Product Description

Product Description:

ERW steel pipes are made of either carbon steel or a low alloy steel, and their choice of material depends on the purpose and the requirements for a project. The size range of these pipes varies greatly, including from small pipes used in plumbing to large-diameter pipes used in oil and gas pipelines. In addition, these pipes have a smooth surface finish which is either bare or comprised of protective layers, like a galvanized coating or anti-corrosion coating.

ERW steel pipes have many uses in different sectors. These pipes are heavily used in water and wastewater transportation, oil and gas pipelines, structural and construction purposes, HVAC systems, industrial and commercial plumbing, and mechanical and engineering applications.



Advantages of ERW Steel Pipes

ERW steel pipes are manufactured from high-quality steel materials, which provide excellent strength and structural integrity. This makes them capable of withstanding high-pressure conditions and heavy loads.

In addition, these pipes have a wide range of sizes, from small diameters to large diameters. This level of versatility makes them suitable for different requirements and applications.

Finally, ERW pipes have an excellent weldability due to the electric resistance welding process used in manufacturing. This creates a strong and reliable weld seam along the length of the pipe, which ensures a consistent and durable connection between pipe segments.


Technical Parameters:

Size Range of ERW Steel Pipes

ERW steel pipes come in a wide range of sizes, mostly determined by their outer diameter (OD) and wall thickness. They range from a few millimeters in diameter with small OD piping, to large-diameter pipes with OD exceeding several feet.

Wall Thickness of ERW Steel Pipes

In addition to their size, ERW steel pipes come in different wall thicknesses, depending on the intended usage. Thewall thickness is usually measured either in millimeters or inches, which has some effect on the overall strength and pressure ratings of the piping.

Length of ERW Steel Pipes

ERW steel pipes are usually available in standard lengths, such as 6 meters (20 feet) or 12 meters (40 feet). However, customization to other lengths is also available, depending on specific project requirements.

Material Grade of ERW Steel Pipes

ERW steel pipes are typically made in different grades of steel, which are determined by their mechanical properties and suitability for specific applications. Common material grades include carbon steel (e.g., ASTM A53, API 5L) and low alloy steel.



The oil and gas industry extensively utilizes ERW steel pipes for the transportation of oil, gas, and other hydrocarbon fluids. They are extensively employed in pipelines in upstream exploration and production, midstream transportation, and downstream refining and distribution. Moreover, these pipes are also used in water supply and sewage systems for municipal, industrial, and agricultural purposes, due to their capability to transport potable water, wastewater, and irrigation water efficiently and reliably.

Besides, these ERW steel pipes are widely employed in the construction industry for various structural applications. They are utilized for column frameworks, columns, beams, and other structural components, due to their strength and durability for load-bearing structures.
