If you are sourcing high-quality, corrosion-resistant stainless steel pipes for chemical, marine, food, or pharmaceutical applications, SS316L stainless steel is one of the most reliable options. Understanding its dimensions, applicable standards, weight, and technical performance is crucial for buyers to ensure compatibility, durability, and cost efficiency.
What is SS316L Stainless Steel Pipe?
SS316L stainless steel (1.4404/UNS S31603) is a low-carbon, austenitic stainless steel known for its excellent corrosion resistance, especially in chloride-rich and acidic environments. It is widely used in chemical processing, marine equipment, food and beverage systems, and pharmaceutical piping, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking.
SS316L Pipe Dimensions and Standards
316L pipes are manufactured according to international standards including ASTM A312, ASTM A213, DIN 17456, and EN 10216. They are available in seamless and welded forms.
Common dimensions (nominal size, outer diameter × wall thickness):
| Nominal Size (inch) | Outer Diameter (mm) | Wall Thickness (mm) |
|---|---|---|
| 1/2" | 21.3 | 2.0–3.0 |
| 1" | 33.4 | 2.0–4.0 |
| 2" | 60.3 | 2.5–5.0 |
| 4" | 114.3 | 3.0–6.0 |
| 6" | 168.3 | 4.0–8.0 |
Weight chart example (kg/m):
| OD × WT (mm) | Weight (kg/m) |
|---|---|
| 21.3 × 2.0 | 0.65 |
| 33.4 × 3.0 | 1.58 |
| 60.3 × 4.0 | 5.10 |
| 114.3 × 6.0 | 15.45 |
| 168.3 × 8.0 | 32.90 |
How do I calculate the weight of S316L pipes?
To calculate the weight of S316L stainless steel pipe, use the following formula: Weight (kg/meter) = (Outer Diameter - Wall Thickness) × Wall Thickness × 0.02507, where both the outer diameter and wall thickness are in millimeters, and 0.02507 is the material constant for 316L stainless steel (based on a density of approximately 7.98-8.03 grams per cubic centimeter). Multiply the result by the pipe length (in meters) to obtain the total weight.
Mechanical Properties
| Property | S316L Stainless Steel |
|---|---|
| Tensile Strength | 485–620 MPa |
| Yield Strength | 170–210 MPa |
| Elongation | ≥ 40% |
| Hardness | ≤ 217 HB |
| Magnetic Response | Non-magnetic (annealed) |
What is the difference between SS316 and SS316L pipes?
S316L has lower carbon content (≤0.03%), which minimizes carbide precipitation during welding, enhancing corrosion resistance in welded structures.
Can SS316L stainless steel be used in marine environments?
Yes. S316L is highly resistant to chloride-induced corrosion, making it suitable for offshore and seawater applications.
Are SS316L pipes suitable for high-temperature applications?
Yes, S316L can be used up to 400°C for continuous service, but for higher temperatures, 316Ti or 904L may be more suitable.
What standards should I check before purchasing SS316L pipes?
Check compliance with ASTM A312, ASTM A213, EN 10216, or DIN 17456, along with MTC, PMI, and NDT reports to ensure quality and traceability.
