Our carbon steel welded pipe is manufactured via high-frequency resistance welding (ERW) or submerged arc welding (SAW) processes, delivering excellent weld strength, dimensional accuracy and corrosion resistance for B2B industrial applications. Compliant with international standards (ASTM A53/A106, EN 10219/10217, JIS G3452, GB/T 3091/9711), it covers mainstream grades: Q235B, Q345B, A36, A53 Grade B, S235JR, S355JR.
Available in customizable specifications: outer diameter 15mm–1220mm, wall thickness 1.2mm–20mm, lengths of 6m/9m/12m or custom-cut options. Surface treatments include black painted, hot-dip galvanized, epoxy coated to meet different working environment demands. We provide factory-direct competitive pricing for overseas clients, with MOQ of 5 tons, bulk order discounts up to 18%, and flexible delivery terms (FOB/CIF/EXW).
Ideal for fluid transportation (water, oil, gas), structural supports, scaffolding, construction piling, mechanical manufacturing, and agricultural irrigation systems, widely exported to Europe, Southeast Asia, Middle East and North America markets.
