ANSI, MSS and API standards govern flange dimensions and tolerances. ANSI B16.5,titled "Steel Pipe Flanges and Flanged Fittings", is the basic standard. It covers forged steel flanges, sizes NPS 1/2(DN 15) through NPS 24(DN 600). ANSI B16.36 covers Orifice Flanges. The following MSS and API standards are written to supplement B16.5:
MSS SP-6: Flange facings
MSS SP-9: Spot facing for bronze, iron and steel flanges
MSS SP-25: Marking of flanges
MSS SP-39: Bolts and nuts for flanges
MSS SP-44: Large diameter pipe line flanges NPS 22 (DN 550) and NPS 26 (DN 650) through NPS 36(DN 900).
API 6A: Wellhead equipment
API 605: Large diameter flanges for petroleum usage NPS 26(DN 650) through NPS 60(DN 1500)
AWWA C207: Hub flanges |
