What is SMO 254 and why is it used in coiled tubes?
- High-Performance Stainless Steel: SMO 254 (UNS S31254) is a super austenitic stainless steel with high chromium, nickel, and molybdenum.
- Excellent Corrosion Resistance: Resists pitting, crevice, and stress corrosion in chloride-rich environments.
- Coiled Tube Advantage: Flexible installation, fewer fittings, and continuous lines for chemical, offshore, and marine applications.
- Durable and High Strength: Suitable for high-pressure piping and instrumentation systems.
- Custom Dimensions: OD 6 mm–114.3 mm (1/4″–4-1/2″), wall thickness 0.5–8 mm, custom sizes on request.
How is quality ensured for SMO 254 coiled tubes?
- Material Certification (MTC): Compliance with ASTM standards.
- Dimensional checks: Ensuring tight tolerances.
- Surface inspection: Smooth, defect-free finishes.
- Mechanical testing: Tensile, hardness, and elongation verification.
- Non-destructive testing (NDT): If required for critical applications.
How to handle and store SMO 254 coiled tubes?
- Store in dry, ventilated areas to prevent surface contamination.
- Avoid contact with carbon steel or ferrous materials to prevent contamination.
- Handle carefully to avoid bends or dents, preserving coiled integrity.
