316 Stainless Steel Pipe
316 stainless steel pipe is a molybdenum-containing austenitic stainless steel product. The molybdenum element greatly boosts its anti-corrosion performance compared to 304 grade, delivering outstanding resistance to seawater, salt fog, mild acid and alkaline environments. As a top-selling pipeline material for coastal regions, it is widely bulk exported to the Middle East and Turkey for seawater desalination, marine engineering, chemical pipeline and coastal construction projects. We are professional 316 stainless steel pipe manufacturers supporting seamless & welded pipes with customizable specifications for wholesale importers.

Strength of Haiwo 316 Stainless Steel Pipe:

  • Molybdenum alloy composition, far stronger anti-corrosion than 304 stainless steel

  • Excellent seawater & salt spray resistance, no rust under long-term coastal marine exposure

  • Stable tolerance to mild acid, alkali, brine and chemical mediums

  • High tensile strength, good high-temperature performance & long service lifespan

  • Dual production: seamless 316 pipe & welded 316 ss pipe for different budget demands

  • ISO certified raw material, uniform wall thickness, smooth inner & outer surface

  • Support bulk wholesale, low MOQ for regional distributors & engineering contractors

  • Custom cutting, length, surface finish (pickled, polished) available



Main Application of 316 Stainless Steel Pipe:

  • Seawater desalination plant pipeline systems

  • Offshore marine engineering, shipbuilding & coastal platform piping

  • Mild chemical factory acid/alkali fluid transport pipelines

  • Coastal city water supply, drainage and fire protection pipelines

  • Aquaculture seawater circulation piping

  • Oil & gas coastal gathering pipelines
