Premium ERW Pipes & Tubes in Carbon Steel, SS, Duplex & Nickel Alloys. Manufactured to ASTM, API, ASME, and EN Standards with SCH 10 through SCH XXS Options. Lengths Available up to 12m. Tailored Solutions Including Special Grades, Finishes, and TPI Available.
Our ERW (Electric Resistance Welded) Pipes & Tubes are manufactured using advanced cold-forming technology, where high-quality steel coils are shaped into round pipes and joined with a precise electric resistance weld. This process delivers pipes with uniform wall thickness, high dimensional accuracy, and a smooth surface finish — ideal for structural, mechanical, and fluid transportation applications. We offer ERW pipes in diameters ranging from ½ inch to 24 inches, with wall thickness options from SCH 10 to SCH 160, complying with international standards such as ASTM A53, A500, API 5L, EN 10219, and more.
Known for their cost-efficiency, reliability, and strength, our ERW pipes are widely used across construction, water pipelines, fencing, automotive, oil & gas, and general engineering sectors. The available material grades include carbon steel, mild steel, and galvanized steel, which can be customized based on project requirements. All pipes are subjected to non-destructive testing (NDT), hydrotesting, and dimensional inspection, with Mill Test Certificates (MTCs) provided for every shipment, ensuring full traceability and compliance with client specifications.
As an ISO 9001:2015 certified manufacturer and exporter, we supply ERW Pipes & Tubes to various global markets including Europe, Russia, USA, Saudi Arabia, Oman, and Qatar. Our packaging is tailored for safe international delivery, using plastic-capped ends, steel-strapped bundles, waterproof wrapping, and wooden crates upon request. With consistent quality, dependable service, and competitive pricing, we are a trusted source for ERW pipes across both high-volume and custom engineering applications.
