316 Stainless Steel Pipe Sizes and Dimensions
The sections below provide OD, wall thickness, and weight per foot for the three most commonly ordered schedules: 10S, 40S, and 80S. 316 stainless steel pipe is available from NPS 1/8" to 24" (DN 6 to DN 600) in schedules 5S, 10S, 40S, 80S, 120, 160 and XXH.
Schedule 10 (Sch 10S) Dimensions
Schedule 10S is the thinnest standard wall for 316 stainless steel pipe. It is best for low-pressure lines, drainage, and structural uses where holding high pressure is not the main requirement.
| NPS | OD (inches) | OD (mm) | Wall Thickness (inches) | Wall Thickness (mm) | Weight (lb/ft) |
|---|---|---|---|---|---|

| 12" | 12.750 | 323.8 | 0.180 | 4.57 | 24.17 |
Schedule 40 (Sch 40S) Dimensions
Schedule 40 is the most commonly used wall thickness for 316 stainless steel pipe in general piping, mechanical systems, and plant utilities. It offers a good balance between pressure capacity and cost.
| NPS | OD (inches) | OD (mm) | Wall Thickness (inches) | Wall Thickness (mm) | Weight (lb/ft) |
|---|---|---|---|---|---|
| 1/8" | 0.405 | 10.3 | 0.068 | 1.73 | 0.24 |

| 12" | 12.750 | 323.8 | 0.375 | 9.52 | 49.56 |
Schedule 80 (Sch 80S) Dimensions
Schedule 80 pipe has a thicker wall, so it can handle higher pressure, steam lines, and heavy-duty use. The thicker wall makes the inside diameter smaller, but it greatly increases the safe working pressure.

316 Stainless Steel Pipe Price
316 SS pipe prices in the Indian market for common sizes and forms range from approximately INR 200 to 400 per kg and internationally range from $3 to $15 per foot for welded pipe and $5 to $25 per foot for seamless, depending on diameter and schedule.
Nickel and molybdenum prices have the biggest impact on 316 pipe costs. When LME nickel prices go up, 316 pipe prices usually increase within 4 to 6 weeks. Buying in bulk, such as full bundles or container loads, gives you a lower price per piece than buying single lengths. Contact our sales desk with your required size, schedule, quantity and delivery location for a current quotation. We provide competitive pricing for both domestic Indian orders and export shipments worldwide.
Chemical Composition of 316 Stainless Steel Pipe
316 stainless steel pipe resists corrosion because it contains carefully balanced amounts of chromium, nickel, and molybdenum, as specified by ASTM A312 / ASME SA‑312.

316 Stainless Steel Pipe Applications
316 stainless steel pipe serves major industry sectors where chloride resistance, mechanical strength, and hygienic properties are non-negotiable.
Chemical and Petrochemical Processing
316 SS pipe is widely used for chemical transfer lines handling acids, alkalis, and chloride-containing fluids. It resists pitting, making it suitable for refineries, sour gas service, and elevated temperature applications.
Marine and Offshore
It is widely used in shipboard systems, offshore rigs, desalination facilities, and coastal structures that demand durable, long-term corrosion protection.
Food, Beverage, and Pharmaceutical
Its resistance to corrosion from cleaning agents and food acids makes it a top choice for sanitary systems and is often used in dairy, brewing, and pharmaceutical processing, as well as in systems requiring high-purity water.
Water Treatment
Water treatment facilities use 316 stainless steel pipe for chlorinated water systems, chemical dosing lines, and filtration units.

304 vs 316 Stainless Steel Pipe: Comparison
316 stainless steel pipe outperforms 304 in chloride and chemical resistance because of its 2 to 3% molybdenum content.
The comparison table below highlights the 7 key differences between these two grades for pipe buyers.
| Property | 304 Stainless Steel Pipe | 316 Stainless Steel Pipe |
|---|---|---|
| Chromium (Cr) | 18.0 to 20.0% | 16.0 to 18.0% |
| Nickel (Ni) | 8.0 to 10.5% | 10.0 to 14.0% |
| Molybdenum (Mo) | None | 2.00 to 3.00% |
| Tensile Strength (min) | 515 MPa (75 ksi) | 515 MPa (75 ksi) |
| Chloride Pitting Resistance | Moderate | Superior |
| Relative Cost | Lower (baseline) | Higher (15 to 25% premium) |
| Typical Applications | Indoor processing, freshwater, structural | Marine, chemical, pharmaceutical, saltwater |
The distinction is corrosion behaviour. In a chloride-free indoor environment, 304 pipe performs perfectly well at a lower price point. Once chlorides enter the equation, 316 becomes the safer specification.
