1/2 in (15 mm) Slip-On Forged Flange, BS10 Table H | SFHS15
Available
This AAP slip-on forged flange is made from forged steel to BS10 Table H (manufacturer-stated). It is supplied in 9 sizes from 1/2 in (15 mm) to 6 in (150 mm).
A slip-on flange slides over the end of the pipe and is fillet welded to it. It is easier to align than a weld neck flange and suits general pipework. AAP describes forged steel flanges as commonly specified in the oil, gas, petrochemical and mining sectors, where pressure, temperature and safety considerations are higher. They are hot forged and then machined.
AAP's temperature-pressure table for carbon steel flanges rates Table H at 3,500 kPa (35 bar) from -50 to 232 °C, stepping down as temperature rises above 232 °C, with a maximum hydrostatic test pressure of 5,250 kPa. That table is headed for plate flanges, so confirm the rating with AIMS if your duty is close to the limit.

Selecting the right option
Check the pipe outside diameter against the flange bore before ordering. Match the standard and table or class to the mating flange and compare the drilling dimensions listed on this page, because flanges made to different standards are not interchangeable. Gaskets and bolting are not part of this listing. If you are not sure what suits, contact AIMS with the standard and size of the mating flange.
