316 stainless steel pipe is suitable for chemical, pharmaceutical, coastal or salt spray environments, water treatment, higher-grade food pipelines, heat exchangers, marine engineering and chloride-containing media. For higher corrosion, pressure or hygiene requirements, confirm 316 or 316L before ordering.
Material Summary
| Core advantages | Molybdenum-bearing stainless steel with better resistance to pitting, crevice corrosion and chloride-containing environments than 304. |
|---|---|
| Typical applications | Chemical processing, pharmaceutical equipment, coastal or salt spray environments, water treatment, higher-grade food pipelines, heat exchangers, marine engineering and chloride-containing media. |
| Purchasing notes | Confirm 316 or 316L, molybdenum content, intergranular corrosion requirements, pickling and passivation, roughness, pressure test and third-party material certificate when needed. |
Pipe Specification Table
| Outside diameter / OD | Common purchasing range: Φ6mm-325mm; corrosion and pressure projects may use standard series, non-standard OD or drawing-based production. |
|---|---|
| Wall thickness / WT | Common purchasing range: 0.3mm-10mm; chemical, pressure and heat-exchanger applications often confirm wall thickness grade or Schedule, with heavier wall options. |
| Length | 6m is standard; fixed length, random length, coil or long length can be discussed according to project and transport limits. |
| Surface finish | BA, 2B, brushed, polished, pickled and passivated, mirror finish. Chemical, pharmaceutical and coastal environments often require passivation or fine polishing. |
| Manufacturing process | Welded stainless steel pipe or seamless stainless steel pipe; cold drawn, cold rolled, hot rolled, solution treated, pickled and passivated, internal and external polished options. |
| Common standards | ASTM A312, ASTM A269, ASTM A270, ASTM A778; JIS G3459; GB/T 12771, GB/T 14976. |
| Ovality tolerance | Confirm by execution standard or drawing. The order should define outside diameter, wall thickness, ovality / out-of-roundness and inspection requirements. |
| Industry use | Chemicals, pharmaceuticals, coastal or salt spray environments, water treatment, high-grade food piping, heat exchangers, marine engineering and chloride environments. |
| Customization | 316 / 316L, sanitary internal polishing, pickling and passivation, pressure testing, NDT and material certificate can be customized by order. |
Purchasing Notes
For chloride, chemical or pressure service, define the medium, temperature, pressure, target standard and inspection scope before placing an RFQ.
