Stainless Steel Pipe | ASME-Compliant 316L Pressure Pipes

Stainless Steel Pipe | ASME-Compliant 316L Pressure Pipes

Product Overview

Our ASME-Compliant 316L Stainless Steel Pressure Pipes are engineered for demanding industrial applications requiring superior corrosion resistance, high-temperature stability, and compliance with rigorous ASME SA213/ASTM A312 standards. Designed for chemical processing, 2 inch stainless steel exhaust pipe systems, and double wall stainless steel chimney pipe installations, these pipes combine seamless construction, precision tolerances (±0.1mm), and customizable specifications to ensure leak-proof performance in extreme environments.

Technical Specifications

Key Attributes

1. Corrosion Resistance:
   • 16-18% chromium and 2-3% molybdenum resist chloride-induced pitting in marine, chemical, and high-humidity environments.
   • Low carbon content (≤0.03%) minimizes carbide precipitation during welding.
2. Thermal Stability: Withstands temperatures up to 870°C (1,600°F), ideal for double wall stainless steel chimney pipe systems and exhaust manifolds.
3. Hygienic Design: Electropolished surfaces (Ra ≤0.3μm) meet FDA and EHEDG standards for pharmaceutical and food-grade applications.

Detailed Performance Characteristics

Tensile & Bend Strength

• Tensile Strength:
  ≥485 MPa tensile strength ensures structural integrity in high-pressure systems like chemical reactors and hydraulic lines. The molybdenum-enhanced microstructure prevents stress corrosion cracking, critical for welded joints.
• Bend Strength:
  Cold-drawn seamless pipes retain ductility under tight-radius bends (1.5x OD). Use mandrel bending tools for cutting stainless steel pipe applications to avoid work hardening.

Identification Methods

• Laser Etching/Stamping: Permanent markings include grade ("316L"), OD, thickness, and heat number per ASTM A480.
• Certification: Mill Test Reports (MTRs) validate chemical composition (Cr:16-18%, Ni:10-14%, Mo:2-3%) and mechanical properties.

Weight Calculation

Use the formula:
Weight (kg/m)=1000(OD−WT)×WT×0.0248
Example: A 50mm OD pipe with 2mm wall thickness weighs ~2.3 kg/m. Download our stainless steel pipe dimensions chart for bulk calculations.

Causes of Stainless Steel Rust

Despite its corrosion resistance, rust can occur under:

1. Chloride Exposure: Seawater or de-icing salts degrade the passive chromium oxide layer, causing pitting.
2. Mechanical Damage: Scratches from improper cutting stainless steel pipe techniques expose raw metal to oxidation.
3. Galvanic Corrosion: Contact with carbon steel in conductive fluids accelerates degradation.
4. Improper Welding: High heat input during welding causes chromium carbide precipitation. Solution: Use argon back-purging and ER316L filler wires.

Applications

• Exhaust Systems: 2 inch stainless steel exhaust pipe for automotive and industrial high-temperature gas discharge.
• Chemical Transport: Seamless 316L pipes handle sulfuric acid, chlorides, and alkalis in reactors.
• Chimney Systems: Double wall stainless steel chimney pipe with thermal insulation for boilers and HVAC.
