Stainless Steel 316 Welded Pipe Manufacturer and Supplier

Stainless Steel 316 Welded Pipe is an austenitic chromium-nickel-molybdenum pipe produced by welding rolled strip under ASTM A312 / ASME SA-312, Grade TP316 (UNS S31600). The alloy has 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. Molybdenum gives this grade of pipe higher pitting and crevice corrosion resistance in chloride-containing environments than 304. Minimum tensile strength sits at 515 MPa (75 ksi), with yield strength at 205 MPa (30 ksi) and elongation at 35%. These values make the pipe suitable for moderate-pressure and structural service.

Stainless Steel 316 Welded Pipe Price

Alloy 316 welded pipe prices in India range from approximately ₹300 to ₹500 per kg. In the US market, common sizes (1” to 4” NPS, Sch 40S) typically cost $5 to $15 per foot. Final pricing depends on outside diameter, wall thickness, schedule, length, quantity, finish, and current nickel and molybdenum market rates. Dual-grade 316/316L pipe carries a small premium compared to single-grade TP316. Sachiya Steel International provides current quotes based on your specific project requirements.

Chemical Composition of Stainless Steel 316 Welded Pipe

This table shows the chemical composition of Grade TP316 (UNS S31600) per ASTM A312 / ASME SA-312.

The 2 to 3% molybdenum content is the primary reason buyers select 316 over 304 grade. It provides measurably better performance in chloride-rich and marine environments where pitting corrosion is a genuine concern.

Industrial Applications of Stainless Steel 316 Welded Pipe

Grade 316 welded pipe serves primary industrial sectors where corrosion resistance and mechanical strength are non-negotiable: chemical processing, marine and offshore, food and pharmaceutical, and water treatment.

Chemical Processing

Chemical plants use 316 stainless steel welded pipe for acid transport, reactor, and heat exchanger connections. At reasonable quantities and temperatures, molybdenum provides good resistance to sulphuric, phosphoric, and acetic acid.

Marine and Offshore

Saltwater exposure demands a pipe grade with strong chloride resistance. SS 316 welded pipe is used for seawater cooling lines, ballast piping, and deck wash systems on offshore platforms.

Food and Pharmaceutical

Milk, beverage, and pharmaceutical plants use 316 grade for their non-reactive surface in sanitary pipes. The alloy won't pollute process fluids or deteriorate under CIP wash cycles.

Water Treatment

TP316 welded pipe is used for filtering skids, chemical dosing lines, and desalination feed pipework in municipal and industrial water treatment facilities. Chlorinated water and mild brine don't damage welds or parent materials.

Stainless Steel 316 Welded Pipe vs Seamless Pipe

Seamless pipe is crucial for extremely high-pressure boilers, but SS 316 welded pipe offers optimal corrosion resistance and value for the majority of industrial processing and structural applications.

Feature	SS 316 Welded Pipe	SS 316 Seamless Pipe
Manufacturing	From cold-rolled strip/plate via welding	From solid billets via extrusion
Size Availability	Up to 100" (EFW)	Generally limited to 24" NPS
Dimensional Accuracy	High (Uniform wall thickness)	Lower (Potential wall eccentricity)
Pressure Capacity	Moderate (Standard 85% joint factor)	High (No longitudinal weld)
Surface Quality	Excellent internal and external finish	May require additional pickling
Cost Efficiency	More economical for large diameters	Higher production and material costs

Frequently Asked Questions:

Can Stainless Steel 316 Welded Pipe Be Welded Further On-Site? +

Yes, SS 316 welded pipe has excellent weldability using TIG (GTAW), MIG (GMAW), and SMAW processes. Use ER316L filler wire and back-purge with argon to prevent oxidation. Post-weld heat treatment isn't generally required.

What is the Price of Stainless Steel 316 Welded Pipe per Kg? +

Prices range from approximately ₹300 to ₹500 per kg in India and $5 to $15 per foot in the US market. Size, schedule, quantity, and current raw material costs all affect the final price. Request a quote for current rates.

Is 304 or 316 Welded Pipe Better for Corrosive Environments? +

316 welded pipe outperforms 304 in corrosive conditions, particularly where chlorides, acids, or saltwater are present. The 2 to 3% molybdenum in 316 gives it significantly better pitting and crevice corrosion resistance than 304 grade.

What Schedules are Available for SS 316 Welded Pipe? +

Schedule 5S, 10S, 40S, and 80S per ASME B36.19M are the standard options. Sch 10S and 40S are the most widely stocked across suppliers.

What is the Difference Between SS 316 Welded Pipe and Seamless Pipe? +

Welded pipe is produced from rolled strip joined by a longitudinal weld seam. Seamless pipe is extruded from a solid billet with no weld seam. Welded pipe costs less and suits general-purpose service. Seamless is specified for high-pressure and critical-service lines.

What Size Range is Available for 316 Stainless Steel Welded Pipe? +

SS 316 welded pipe is available from 1/8” (6 mm) to 24” (600 mm) NPS as standard per ASTM A312. Larger sizes are available on request per ASTM A358. Standard length is 20 feet (6 metres), with custom cuts produced as per client specification.

What ASTM Specification Covers 316 Welded Pipe? +

ASTM A312 / ASME SA-312 is the primary specification for welded austenitic stainless steel pipe, including Grade TP316. For electric-fusion-welded pipe in high-pressure applications, ASTM A358 / ASME SA-358 applies.

What is the Maximum Operating Temperature for SS 316 Welded Pipe? +

SS 316 welded pipe can serve continuously up to approximately 870°C (1600°F). Intermittent service allows temperatures up to 925°C (1700°F). Above these limits, consider upgrading to 316H or another high-temperature grade.
