High-Performance Stainless Steel Pipes – Superior Corrosion Resistance

As a specialized manufacturer of premium Stainless Steel Pipes, FOREVER STEEL provides high-integrity piping solutions engineered for sanitary, high-pressure, and highly corrosive industrial environments. Our products are manufactured through advanced cold-drawing, cold-rolling, and precision welding processes, ensuring exceptional surface finishes and precise dimensional tolerances.

Dimensional Specifications & Product Range

We offer a comprehensive matrix of stainless solutions to meet diverse engineering scales:

Manufacturing Process: Seamless (SMLS) & Welded (ERW/EFW).

Outside Diameter (O.D.): 1/4"–48" (6mm–1219mm).

Wall Thickness (W.T.): SCH 5S, SCH 10S, SCH 40S, SCH 80S (Compliant with ASME B36.19M).

Length: Fixed Length: 5.8m, 6.0m, 11.8m, 12.0m.

Customized: Precision cutting to specified project lengths.

Global Standards & Material Compliance

Our production strictly adheres to international metallurgical benchmarks to ensure global project compatibility:

Standard Frameworks: ASTM A312, A213, A269, A358; EN 10216-5, EN 10217-7; JIS G3459.

Austenitic Grades: 304/304L, 316/316L (Marine Grade), 321, 347/347H.

Duplex & Super Duplex: S31803, S32205, S32750 (For high-chloride environments).

High-Nickel Alloys: 904L, Alloy 20, Monel, Inconel (Upon specialized request).

Precision Surface Finish & End Preparation

To meet the "Clean-In-Place" (CIP) requirements and high-purity standards:

Surface Treatment: * Pickled & Annealed (AP): For standard industrial corrosion resistance.

Bright Annealed (BA): For mirror-like finish and internal smoothness.

Polished: Grit 180, 240, 320, 400, 600 (Satin or Mirror Finish).

End Preparation: * Plain Ends: Square cut and deburred for orbital welding.

Bevelled Ends: Precisely machined to 30°per ANSI B16.25 for heavy-wall pipes.

Threaded Ends: NPT/BSPT for instrumentation applications.

Critical Industry Applications

Our stainless solutions are the benchmark for reliability in:

Sanitary & Food Grade: Dairy, beverage, and pharmaceutical processing.

Petrochemical: Corrosive fluid conveyance and offshore oil platforms.

Energy & Heat Exchange: Condensers, heat exchangers, and high-pressure boilers.

Semiconductor: Ultra-high purity (UHP) gas delivery systems.

Rigorous Quality Assurance (QA/QC)

Metallurgical Testing: Positive Material Identification (PMI), Intergranular Corrosion (IGC) Test, and Microstructure Analysis.

Structural Integrity: 100% Hydrostatic Testing, Eddy Current (ET), or Ultrasonic Testing (UT).

Compliance: Mill Test Certificates (MTC) issued according to EN 10204 3.1 (3.2 available).

Third-Party Inspection: Full cooperation with SGS, TUV, or BV for pre-shipment release.

Export Logistics & Protective Packaging

We prioritize the arrival of your cargo in "Pristine" condition, free from scratches or atmospheric contamination:

Packaging: * Individual plastic bagging for polished pipes to prevent surface abrasion.

Plywood cases or reinforced steel-frame crates for LCL shipments.

Bundle wrapping with woven material for FCL shipments.


Shipping Security: * Use of nylon slings and specialized handling equipment to avoid carbon steel cross-contamination.

Sea-worthy bracing and moisture-proof desiccant within containers.

Heavy-duty plastic end caps to protect internal cleanliness and bevel integrity.
