316 / 316L Stainless Steel Pipe | Seamless & Welded Tube Supplier

Product Overview

Wuxi Xinshanhu Steel Co., Ltd. supplies premium-grade 316 and 316L stainless steel piping solutions. By incorporating 2-3% Molybdenum, Grade 316 provides vastly superior resistance to chlorides and pitting compared to standard 304. Grade 316L (Low Carbon ≤0.03%) eliminates carbide precipitation during welding, ensuring structural integrity in highly aggressive, chemical-heavy, or saline environments. Available in high-pressure seamless and large-diameter welded configurations.

Types & Specifications

Product Advantages

Superior Chloride Resistance: Exceptional defense against pitting and crevice corrosion in seawater and marine atmospheres.
No Weld Decay: 316L carbon restriction ensures zero intergranular corrosion after heavy-gauge welding.
Excellent Elevated Temperature Strength: Better creep, stress-to-rupture, and tensile strength at high temperatures than 304.
Ultra-Smooth Interior (Optional): Available with internal polishing to prevent biological fouling and optimize fluid flow.

Applications

Marine and offshore structures
Chemical and pharmaceutical piping
Food and beverage processing equipment
Architectural and decorative tubes

Quality Control & Testing (Zero Defects)

To guarantee 100% compliance with ASTM/ASME standards, every production batch goes through:

• Material Verification: 100% PMI testing before packing to ensure correct Mo and Ni ratios.
• Flaw Detection: Full-body Ultrasonic (UT) or Eddy Current testing to eliminate internal cracks or laminations.
• Pressure Proofing: Hydrostatic testing calibrated to specific schedule requirements to ensure 100% leak-free performance.
• Mechanical & Corrosion Tests: Intergranular corrosion tests (ASTM A262 Practice A/E) available upon request.
• Third-Party Inspection: Fully certified for SGS, BV, TUV, or ABS inspections.

Packaging & Safe Shipping

Surface Protection: Every pipe is end-capped and individually sleeved in plastic to prevent scratching and atmospheric oxidation during long ocean voyages.
Heavy-Duty Crating: Wrapped in bundles with steel strapping, or crated in reinforced, IPPC-certified seaworthy wooden boxes.
Load Security: Expertly braced inside containers to prevent shifts, moisture build-up, and mechanical damage.

FAQ

Q: How do you guarantee the Molybdenum (Mo) content in your 316L pipes?
A: Every single order comes with an authentic EN 10204 3.1 Mill Test Certificate (MTC). We also perform 100% PMI (Positive Material Identification) testing before dispatch to verify exact chemical compositions.
Q: Do you offer 316L pipes specifically for high-pressure applications?
A: Yes. Our seamless 316/316L pipes are strictly annealed and hydrostatic-tested, meeting ASTM A312 standards for high-pressure industrial fluid control.
Q: Can I get cut-to-length pipes to reduce on-site welding?
A: Absolutely. Our fiber laser cutting service provides exact定尺 (cut-to-length) pipes with perfectly clean, burr-free edges.
