Premium Seamless & Welded Stainless Steel Pipes: Engineered for Demanding Global Applications

Uncompromising Quality, Unmatched Versatility

Elevate your industrial projects with our precision-crafted seamless and welded stainless steel pipes. Designed to excel in the most corrosive and high-pressure environments, our pipes combine superior metallurgy, advanced processing, and rigorous quality control to deliver reliable performance you can trust.

Key Material Grades for Superior Performance:

• 310S: Exceptional high-temperature oxidation resistance (up to 1150°C / 2100°F). Ideal for furnaces, heat treatment.

• 316L: Superior corrosion resistance, especially against chlorides and acids. The gold standard for marine, chemical, and pharmaceutical applications.

• 304 / 304N: Excellent all-purpose austenitic stainless steel. Outstanding formability and corrosion resistance for general use.

• S30815 (253 MA): Enhanced high-temperature strength and oxidation resistance. Perfect for thermal processes.

• 301 / 301L: High strength and good ductility. Excellent for structural components requiring formability.

• S32305 (Duplex): Outstanding strength (2x 304/316) and superior corrosion/erosion resistance, especially in chloride environments. Ideal for offshore, oil & gas.

Engineered for Critical Applications:

• Oil & Gas: Downhole tubing, pipelines, manifolds, separators (Resisting sour service, chlorides, high pressure).

• Chemical Processing: Reactors, heat exchangers, transfer lines, effluent handling (Resisting acids, alkalis, pitting).

• Machinery & Equipment: Hydraulic systems, instrumentation lines, food processing conveyors, architectural components.

Precision Manufacturing & Value-Added Processing:

1. Expert Bending: Precision cold or hot bending capabilities to meet complex design specifications (mandrel bending available).

2. Thorough Cleaning: Advanced degreasing, pickling, and passivation processes ensure optimal corrosion resistance and contaminant-free surfaces, ready for installation or further fabrication.

Premium Surface Finishes for Every Need:

• Mirror Polish (BA/No.8): Ultra-smooth, highly reflective finish for aesthetic appeal, hygiene-critical applications (food, pharma), and easy cleaning.

• Standard 2B: Smooth, lightly reflective cold-rolled, annealed, and pickled finish. The most common versatile finish for industrial applications.

• Polished (Various Grits): Customizable smoothness (e.g., #180, #240, #400) to meet specific aesthetic or functional requirements.
