SS 316L ERW Pipe, SS UNS S31603 Hollow Pipe, SS GOST 03Ch17N14M3 Round Pipe, ASTM A312 TP316L Welded Pipe, 316L Stainless Steel Seamless Pipe Supplier in India.

Reliable Pipes & Tubes – SS ERW Pipe 316L Manufacturer & Supplier in India

Stainless Steel 316L Pipe is made up of an austenitic stainless steel that has chromium, nickel and molybdenum in its composition with low carbon content than the 316 grade. The low carbon content of the pipes makes it easier for welding applications. The SS ERW Pipe 316L is used in aqueous applications where chloride ion corrosion is high. The material has low corrosion rates in chloride ion rich environment because of the molybdenum content in it. There are welded, seamless and fabricated pipes.

The 316L Stainless Steel Seamless Pipe is used in more dimensionally accurate applications. The pipes have lower carbide precipitation while welding and reduce the intergranular corrosion and localized corrosion. The seamless pipes range from ½ inches to 16 inches. The Stainless Steel 316L Welded Pipe ranges from ½ inches to 24 inches and the electric fusion welded pipes range from 6 inches to 100 inches. The tubular products are suitable for high pressure and high temperature services in this grade of material.

The ASTM A312 TP316L Pipe has 205 MPa minimum yield strength and 515 MPa minimum tensile strength. The pipes can also operate under elevated temperatures up to 870 degrees Celsius. The SS 316L ERW Pipe is created by welding a piece of the sheet from end to end or by welding a strip spirally. The welded pipes have more absolute roughness than the seamless ones and are less accurate in dimensions. The SS UNS S31603 Hollow Pipe is used in various industrial, commercial and general corrosive service applications.

Frequently Asked Questions (FAQs)

What is SS ERW Pipe 316L?

SS ERW Pipe 316L is a welded stainless steel pipe manufactured using Electric Resistance Welding from 316L grade austenitic stainless steel. It features low carbon content (0.035% max) along with chromium (16-18%), nickel (10-14%) and molybdenum (2-3%), providing excellent resistance to chloride ion corrosion.

What is the difference between SS 316 and SS 316L ERW Pipe?

SS 316L is the low-carbon version of SS 316. The lower carbon content (0.035% max vs 0.08% max) reduces carbide precipitation during welding, minimizing intergranular corrosion. 316L has slightly lower tensile and yield strength (485 MPa / 170 MPa vs 515 MPa / 205 MPa).

What are the size ranges for SS 316L ERW Pipe?

SS 316L ERW Pipes are available from 1/2" NB to 24" NB. Seamless pipes range from 1/2" to 16" NB, and EFW pipes range from 6" to 100" NB. The total size range covers 1/8" NB to 30" NB across all pipe types.

What is the UNS designation for SS 316L?

SS 316L has UNS designation S31603. It is also known as Werkstoff Nr. 1.4404/1.4435 (DIN), SUS316L (JIS), 316S13 (BS), and GOST 03KH17H14M2.

What is the maximum operating temperature for SS 316L Pipe?

SS 316L Pipes can operate under elevated temperatures up to 870°C (1598°F). They are suitable for high pressure and high temperature service applications.

What is the price of SS 316L Pipe in India?

The price ranges from approximately 184 INR per unit for welded pipes to 340 INR per unit for seamless pipes (ASTM A312 Grade TP316L). Contact Reliable Pipes & Tubes for the latest pricing and competitive quotation.

What surface finishes are available for SS 316L Pipe?

Available surface finishes include AP (Annealed & Pickled), BA (Bright Annealed), MP (Mechanical Polish) and EP (Electro Polish). The roughness average ranges from 5 μinch (0.13 μm) for electro polished to 40 μinch (1.0 μm) for annealed & pickled finish.

What is the tolerance for SS 316L Pipe?

The tolerance for ASTM A312 TP316L Pipe varies by OD: 4-35 mm (+/- 0.08 mm), 35-38 mm (+/- 0.15 mm), 38-60 mm (+/- 0.20 mm), and 60 mm and above (+/- 0.25 mm).
