AANSI/ASMI B16.5 SLIP-ON PIPE FLANGES - Stainless Steel ASTM A182 F316L, 317L

Stainless Steel ASTM A182 F316/316L/316H Slip-on flanges, Monel ASTM A564 400/K500 Slip-on flanges, Nickel 200/201 Slip-on flanges, ANSI B16.5 ASTM A182 Inconel 600/601/625 Slip-on flanges, Incoloy 800/800H/800HT Slip-on flanges, Titanium Gr1/Gr2/Gr5/gr11 Slip-on flanges, SS ASTM A182 304/304L Slip-on flanges, SS ASTM A182 309S/310S/317L Slip-on flanges, Carbon Steel ASTM A105 Slip-on flanges, Duplex Steel ASTM A182 F44/F45/F51 Slip-on flanges, Duplex Steel ASTM A182 F53/F55/F56 Slip-on flanges, Alloy Steel F11/F22/F91 Slip-on flanges

According to their name, these pipe flanges slip over the pipe, that is why it is called slip-on flange. It is fabricated with an inside diameter that is bigger than the pipe’s outside distance across. These connections are associated with the pipe by means of filet weld at the top and base of the flange.

Slip on pipe flanges are used with a raised or flat face. At the time of raised face, the standard height would be 1/16" for slip on pipe flanges under 400# while for slip on pipe flanges of 400#, the standard height would be 1/4".

The Slip On pipe flanges include materials carbon steel slip-on pipe flanges, stainless steel slip on pipe flanges and alloy steel slip on pipe flanges available in various class such as 150 LBS, 300 LBS, 600 LBS, 900 LBS. These flanges are ideal for low pressure applications.

Advantages/Features of Slip-on Flanges:
  • They need on low pressure temperature environments
  • They are leak-proof
  • Installation cost is low
  • It allows easier alignment of bolting holes because of its smaller thickness
  • One size is appropriate for all pipe schedules
