In today's interconnected industrial landscape, where performance, reliability, and cost-efficiency are non-negotiable, S355JR and A106 Grade B carbon steel pipes have become the preferred materials for demanding engineering applications. These high-performance carbon steel pipes are essential components in oil and gas transmission, power generation, marine engineering, civil infrastructure, and chemical processing projects across the globe.

At our ISO9001- and CE-certified manufacturing facility, we produce seamless and welded carbon steel pipes that meet and exceed ASTM A106 and EN 10025-2 (S355JR) standards. With full traceability, robust quality control, and fast delivery cycles, we are a trusted supplier for international EPC contractors, distributors, and OEM manufacturers.

Why Choose Our Carbon Steel Pipes?

S355JR and A106 Grade B pipes offer:

High tensile and yield strength for structural reliability

Excellent corrosion resistance in aggressive environments

Tight dimensional tolerances for seamless integration

Versatile surface treatments, including black paint, galvanizing, epoxy coating, and pickling

Full customization of diameter, wall thickness, length, and end finishes (plain, beveled, or threaded)

We offer seamless pipes for high-pressure and high-temperature lines, and welded pipes (spiral or longitudinal) for general-purpose applications. All pipes undergo hydrostatic, ultrasonic, and dimensional testing to ensure compliance with ASME, JIS, EN, and DIN specifications.
