Product description

Highlights at a glance

1.Our carbon steel pipes deliver reliable strength and consistent mechanical properties for general industrial applications. With strict control over carbon content and impurity levels, they perform dependably in structural support, fluid transportation, and low-to-medium pressure systems across construction, machinery, and automotive sectors.

2.Manufactured through advanced hot-rolling and cold-drawing processes, our pipes feature fine grain structure and uniform hardness. Each pipe undergoes hydrostatic testing and non-destructive inspection to guarantee integrity under working pressures, ensuring safety in boiler tubes, heat exchangers, and hydraulic systems.

3.Available in outside diameters from 21.3mm to 1420mm and wall thickness from 2.11mm to 300mm, in seamless or welded types. Diameter tolerance: OD ±1%, WT ±10%, strictly controlled within ASTM/API/BS/DIN/GB/JIS standards. Materials cover 10#/20#/45#/Q235/Q345, ASTM A53/A106/API 5L, and heat-resistant grades like T91/T92/P91/P92 and 15CrMo for elevated temperature service.

4.Ideal for engineers building structural frameworks, oil and gas pipelines, power stations, and heavy machinery. With excellent weldability and formability, fabrication time is reduced. Full mill test certificates and third-party inspection (ISO/BV/SGS/MTC) are available upon request.

5.Fast shipping within 7-10 working days from major Chinese ports. Steel strip packed with standard export seaworthy packaging suitable for all transport modes. We provide end-beveling, threading, painting, and galvanizing services. Small trial orders from 1 ton accepted. Flexible payment options available.
