1. 316L stainless steel blind flange usage

A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.

Blind flange with 1/2 npt tapped thread

These include NPT tapped holes and special threads to allow pressure test connections to be fitted. Blind flanges are generally used to blank off the ends of pipe. They are also used on similar valves and pressure vessel openings. Because they are often located at the ends of systems, these flanges often are among the highest stressed flange types.

2. 316L material introduction:

Standards:

  • ASTM/ASME: UNS S31600 / S31603
  • EURONORM: X1 CrNiMo 17 12 2 / X3 CrNiMo 17 12 2
  • AFNOR: Z 6 CND 17-11 / Z 2 CND 17-12
  • DIN: 1.4401 / 1.4404

Corrosion Resistance:

  • Generally more resistant than 304 in range of atmospheric environments and many corrosive media due to the increased chromium
    and molybdenum content.
  • Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 122°F (50°C).
  • Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at
    140°F (60°C).
  • Usually regarded as the “marine grade stainless steel” – but is not resistant to warm sea water.

Heat Resistance:

  • Good oxidation resistance in intermittent service to 1600°F (870°C) and in continuous service to 1700°F (925°C)
  • Grade 316L is more resistant to carbide precipitation.
