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.

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)

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.

NPS OD (inches) OD (mm) Wall Thickness (inches) Wall Thickness (mm) Weight (lb/ft)

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.

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.

Frequently Asked Questions:

What is 316 stainless steel pipe? +
316 stainless steel pipe is a corrosion‑resistant chromium‑nickel‑molybdenum alloy pipe (UNS S31600) made to ASTM A312/ASME SA‑312, available in seamless, welded, and ERW forms.
What is the price of stainless steel 316 pipe per kg? +
316 stainless steel pipe usually costs about INR 200-400 per kg in India. Actual price is influenced by several factors: the pipe's dimensions, the thickness of its walls, whether it's seamless or welded, and the current state of the market.
What is the difference between 304 and 316 stainless steel pipe? +
316 contains 2-3% molybdenum, giving much better resistance to chlorides and saltwater than 304. Both have similar strength; 316 is preferred for harsher, chemical or marine environments.
What sizes are available for 316 stainless steel pipe? +
Sachiya Steel stocks 316 stainless steel pipe from NPS 1/8" to 24" (DN 6–600) in schedules 5S, 10S, 40S, 80S, 120, 160, and XXH, with standard 20‑foot or custom lengths.
What is the pressure rating of schedule 40 316 stainless steel pipe? +
Pressure ratings shall be calculated in accordance with ASME B31.3 based on design temperature, allowable stress, and wall thickness.
What ASTM specification covers 316 stainless steel pipe? +
ASTM A312/ASME SA‑312 mainly covers 316 stainless steel pipe. Additional related standards include ASTM A358, ASTM A778, and ASTM A999 for specific manufacturing and general requirements.
Can 316 stainless steel pipe be used for exhaust systems? +
Yes. 316 stainless steel pipe suits exhaust systems, especially marine or corrosive environments, because its molybdenum content resists acidic condensate and moisture better than lower grades.
Where can I buy 316 stainless steel pipe? +
You can buy 316 stainless steel pipe from Sachiya Steel International, a manufacturer and stockist supplying seamless, welded, and ERW ASTM A312 TP316 pipes with mill test certificates worldwide.
