Stainless Steel Pipe | Heavy-Duty 316 Exhaust Pipe Solutions

Stainless Steel Pipe | Heavy-Duty 316 Exhaust Pipe Solutions

Product Overview

Our heavy-duty 316 stainless steel exhaust pipes are engineered for extreme performance in high-temperature, corrosive, and mechanically demanding environments. Designed for automotive, industrial, and chimney stainless steel pipe installations, these pipes combine superior corrosion resistance, thermal stability, and durability. With certifications compliant with ASTM, ASME, and ISO standards, our solutions ensure reliability in exhaust systems, marine engineering, and chemical processing.

Technical Specifications

Key Attributes

1. Corrosion Resistance: Enhanced by 16-18% chromium and 2-3% molybdenum, resisting pitting and crevice corrosion in chloride-rich environments like marine exhausts.
2. High-Temperature Stability: Maintains structural integrity up to 870°C (1,600°F), ideal for chimney stainless steel pipe systems and automotive exhausts.
3. Mechanical Durability: High tensile and bend strength ensure longevity under extreme stress.
4. Hygienic Design: Smooth surfaces prevent bacterial growth, suitable for food and pharmaceutical industries.

Detailed Performance Characteristics

Tensile & Bend Strength

• Tensile Strength: ≥485 MPa (70,300 psi) ensures reliability in high-pressure systems like turbocharger exhausts and industrial boilers. The molybdenum content enhances resistance to stress corrosion cracking, critical for stainless steel exhaust pipe clamps and welded joints.
• Bend Strength: The austenitic microstructure provides exceptional ductility, retaining roundness under tight-radius bends. This property is vital for custom stainless steel pipe measurements in complex automotive exhaust layouts.

Identification Methods

• Laser Etching/Stamping: Permanent markings include grade ("316"), OD, thickness, and heat number per ASTM A480.
• Certification: Mill Test Reports (MTRs) validate chemical composition (Cr, Ni, Mo) and mechanical properties, ensuring traceability.

Weight Calculation

Use the formula:
Weight (kg/m)=1000(OD−WT)×WT×0.0248
Example: A chimney stainless steel pipe with 101.6 mm OD and 5 mm wall thickness weighs ~11.9 kg/m. For precise stainless steel pipe measurements, contact our technical team.

Causes of Stainless Steel Rust

Despite its corrosion resistance, rust can occur under:

1. Chloride Exposure: Seawater or de-icing salts disrupt the passive chromium oxide layer, causing pitting.
2. Mechanical Damage: Scratches from improper handling expose raw metal to oxidation.
3. Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in conductive fluids accelerates degradation.
4. Improper Welding: Carbon precipitation in heat-affected zones reduces corrosion resistance, mitigated by using low-carbon 316L for welded stainless steel exhaust pipe clamps.

Applications

• Automotive Exhausts: High-temperature stability and bend strength for turbocharged systems.
• Industrial Chimneys: Chimney stainless steel pipe installations resist acidic flue gases.
• Marine Engineering: Chloride resistance for offshore platforms and ship exhausts.
