Overview

SS-SCH40316NIP nipples are manufactured from 316 stainless steel Schedule 40 pipe, delivering maximum corrosion resistance for aggressive environments. With added molybdenum, 316 stainless provides superior resistance to chlorides, saltwater exposure, acidic processing, and chemical attack.

316 SCH40 nipples deliver the strength of standard wall stainless combined with enhanced chemical durability. They are the preferred stainless nipple for marine, offshore, pharmaceutical, chemical, and high-purity installations.

Technical

316 SCH40 nipples follow ASTM A312/A276 material specifications and ASME B1.20.1 NPT threading requirements. The molybdenum alloying (2–3% Mo) enhances resistance to pitting, crevice corrosion, and chloride-induced attack.

  • Material: 316 Stainless Steel (Cr-Ni-Mo alloy)
  • Chemical advantage: Superior chloride, salt, and chemical resistance
  • Wall thickness: Standard Schedule 40
  • Thread type: NPT taper thread, gauged for seal integrity
  • Temperature range: Excellent performance in extreme heat & cold
  • Surface: Deburred, clean, weld-quality pipe

Ideal for severe corrosion environments or high-purity stainless systems.

Applications

316 SCH40 nipples are used for threaded pipe connections in high-corrosion, high-reliability environments.

  • Marine & saltwater piping systems
  • Chemical dosing and transfer lines
  • High-purity water and RO/DI systems
  • Acidic or solvent-heavy processing environments
  • Pharmaceutical CIP/SIP service
  • Instrumentation loops & analyzer tie-ins
  • Pump, valve, and flow-control assemblies

The Schedule 40 wall thickness provides the strength required for industrial pressures while maintaining corrosion superiority.

Industries

  • Marine & offshore platforms
  • Chemical processing plants
  • Pharmaceutical & biotech utilities
  • Food & beverage production
  • High-purity filtration & water treatment
  • Refinery & petrochemical support
  • Brewery/distillery chloride-rich areas

316 nipples are the industry’s go-to choice where corrosion risk is high and reliability is critical.

Integration

316 SCH40 nipples integrate seamlessly with stainless threaded valves, unions, couplings, gauges, pumps, manifolds, and instrumentation components.

  • Marine pump systems & deck fittings
  • Offshore chemical injection skids
  • Pharma utility distribution & CIP systems
  • Corrosive chemical distribution modules
  • High-purity transfer loops

Supports hybrid stainless setups combining threads, sanitary fittings, and compression-to-NPT transitions.
