Key Features & Advantages
Tensile & Bend Strength
Our stainless steel tube pipe sizes are engineered for industrial demands. 316 stainless steel pipe tube offers superior tensile strength (≥550 MPa) due to its molybdenum-enriched alloy (2–3% Mo), making it ideal for high-stress applications like chemical processing and marine environments. The cold-drawn process enhances grain alignment, achieving a 15% higher bend strength compared to hot-rolled alternatives.
Identification & Traceability
Each pipe is laser-etched with:
- Grade Markings (e.g., UNS S31600, S30403)
- Heat Number
- ASTM/EN/JIS Standard Code (e.g., ASTM A312 TP316)
Third-party certifications (TUV, SGS) and Mill Test Reports (MTRs) ensure compliance with stainless steel 304L pipes and tubes specifications.
Weight Calculation
Formula:
Weight (kg/m) = (OD – WT) × WT × 0.02491
Example: A 2" (DN50) Schedule 40S 316 stainless steel pipe tube (OD: 60.3mm, WT: 3.91mm) weighs 5.68 kg/m[(60.3–3.91) × 3.91 × 0.02491].
Corrosion Mechanisms
While stainless steel tube pipe sizes resist rust, localized corrosion can occur due to:
- Chloride Exposure: 304L is vulnerable in seawater; 316’s Mo content prevents pitting.
- Galvanic Coupling: Contact with carbon steel in humid environments accelerates oxidation. Insulating gaskets are recommended.
- Stress Corrosion Cracking (SCC): High chloride + tensile stress (>80°C) may crack 304L. Solution-annealed 316 minimizes this risk.
Applications
- Chemical & Petrochemical: Seamless 316 stainless steel pipe tube for acid transfer (H2SO4, HCl).
- Food & Pharma: Electropolished stainless steel 304L pipes and tubes meet 3-A Sanitary Standards.
- Architectural: Mirror-finished square tubes for handrails and façades.
