Applications of Stainless Steel 316L Welded Pipe

SS 316L welded pipe is used across 5 primary industries due to its molybdenum-enhanced chloride resistance and low-carbon weldability.

Chemical and Petrochemical Processing

These plants use 316L welded pipe for transporting sulphuric acid, phosphoric acid and chloride-bearing process fluids. The alloy’s 2.00-3.00% molybdenum content resists pitting in these aggressive media.

Food, Beverage, and Pharmaceutical

Food & pharmaceutical manufacturers require 316L welded pipe for hygienic piping. The smooth, pickled interior surface prevents bacterial adhesion and withstands CIP (clean-in-place) cycles.

Marine and Offshore

Such applications rely on 316L for seawater cooling lines and ballast systems.

Water Treatment and Desalination

These plants use it for brine handling and reverse osmosis membrane housings.

Oil and Gas

Facilities dealing with oil& gas install this pipe in offshore platforms, refineries and subsea piping systems where saltwater exposure is constant.

Frequently Asked Questions:

What is Stainless Steel 316L Welded Pipe? +
Stainless Steel 316L Welded Pipe is austenitic stainless steel made by welding strip or plate per ASTM A312 / ASME SA-312. The letter "L" indicates a maximum carbon content of 0.030%. This low carbon level prevents the formation of carbides, which helps to improve resistance to intergranular corrosion.
Is 316L Stainless Steel weldable? +
Yes. 316L is designed for excellent weldability. Its low carbon prevents harmful chromium carbide in the heat-affected zone. They show corrosion resistance in TIG, MIG, and submerged arc welding.
What is the price of SS 316L Welded Pipe per Kg? +
SS 316L welded pipe costs about ₹180-325 per kg in India. Final price depends on OD, wall thickness, schedule, quantity, surface finish, and nickel/molybdenum prices. Contact Sachiya Steel International for a project-specific quote.
What is the difference between 316L Welded Pipe and Seamless Pipe? +
316L welded pipe is made by longitudinally welding a strip or plate. Welded pipe costs less, and it’s available in larger diameters (up to 100” NB for EFW). Seamless pipe is extruded from a solid billet, weldless with higher dimensional accuracy, preferred for high-pressure services above SCH 160.
What ASTM standard covers 316L Welded Pipe? +
ASTM A312 / ASME SA-312 covers straight-seam welded austenitic stainless steel pipe. ASTM A358 / ASME SA-358 covers electric-fusion-welded large-diameter pipe with Class I–V radiography. ASTM A778 covers welded, unannealed tubular products for general corrosive service.
