Pipe & Tube

HENGYANG PIPING specializes in manufacturing high-performance seamless and welded steel pipes/tubes designed to exceed industrial demands. Our pipes and tubes are crafted from advanced materials including Austenitic/Ferritic Stainless Steel, Duplex/Super Duplex Steel, Nickel Alloy, Titanium, Copper, and Alloy Steel, ensuring unmatched corrosion resistance, mechanical strength, and adaptability across extreme environments.

Certified to ASTM, ASME, and ISO standards, our steel pipes meet rigorous global quality benchmarks, making them ideal for mission-critical applications in oil & gas, chemical processing, aerospace, and construction.

PRODUCT TYPES & FEATURES

1. Seamless Stainless Steel Pipes
Manufacturing Process: Hot-rolled, cold-drawn, or extruded from solid billets for zero surface seams.
Advantages:
20% higher pressure tolerance vs. welded counterparts.
Uniform wall thickness for precision fluid/gas transport.
Available in diameters 4mm–900mm with custom thickness.
Material Grades: 304/316L, Duplex UNS S32205, Super Duplex S32750, Nickel Alloy 625/825.

2. Welded Stainless Steel Pipes
Welding Technology: ERW (Electric Resistance Welded), DSAW (Double Submerged Arc Welded), and SAW (Spiral Welded).
Advantages:
Cost-effective for large-scale projects.
Seam integrity validated by non-destructive testing (NDT).
Ideal for structural applications (e.g., A139-B, A252 spiral weld).
Material Flexibility: Carbon Steel, Alloy Steel, Copper-Nickel blends.

3. Specialty Alloy Solutions
Duplex/Super Duplex Steel: Combines high strength (2x standard stainless) with chloride resistance for offshore/chemical plants.
Nickel Alloys: Optimized for extreme heat/corrosion (e.g., Inconel® in aerospace).
Titanium Pipes: Lightweight with exceptional biocompatibility for medical/pharmaceutical use.

INDUSTRY APPLICATIONS
1. Oil & Gas: Subsea pipelines, refinery heat exchangers.
2. Chemical Processing: Acid-resistant transport systems.
3. Aerospace: Hydraulic tubing, exhaust components.
4. Construction: Structural supports, water distribution.
5. Medical: Sterile fluid transfer, surgical equipment.
