Electric Resistance Welded Steel pipe
ERW (Electric Resistance Welded) Steel Pipes are a reliable, cost-effective solution for transporting oil, gas, water, and structural applications. Manufactured using high-frequency electric resistance welding, these pipes are available in outer diameters from 21.3mm to 660mm, wall thicknesses of 1mm to 20mm, and lengths ranging from 0.5 meters to 22 meters. Their consistent wall thickness and dimensional accuracy make them suitable for a wide range of industrial and infrastructure applications.
Key Features and Coatings:
ERW steel pipes are offered with a variety of surface coatings to meet different operational requirements and enhance durability. Coating options include Fusion Bonded Epoxy (FBE), Coal Tar Epoxy, 3PE (Three-Layer Polyethylene), Vanish Coating, Bitumen Coating, and Black Oil Coating. These protective layers provide excellent corrosion resistance and prolong the life of the pipes, especially in harsh environments or buried installations.
Standards and Specifications:
These pipes are produced according to major international standards such as API 5L, ASTM A53 GR.B, ASTM A178, ASTM A500/501, ASTM A691, ASTM A252, ASTM A672, EN 10217, and ISO 3183 / GB/T 9711 series. These standards ensure that the pipes meet strict requirements for strength, pressure rating, weld integrity, and toughness. End types are available in square cut, saw cut, or beveled, providing flexibility for welding or mechanical joining.
Applications and Versatility:
ERW steel pipes are widely used in oil and gas transportation, water pipelines, construction, structural supports, and piling projects. Their superior weld quality and ability to withstand high pressure make them ideal for both above-ground and underground installations. The extensive size range and customizable coating options make ERW pipes a versatile choice for projects requiring durability, strength, and cost-efficiency.
Benefits and Reliability:
The electric resistance welding process produces a uniform weld with no filler metal, resulting in smooth internal and external surfaces. This not only enhances flow efficiency in fluid transport but also simplifies installation and reduces the risk of corrosion buildup. ERW steel pipes offer excellent roundness, tight dimensional tolerances, and dependable performance over long service lifespans—delivering great value in demanding applications.
