A flange is a disc with evenly spaced holes for bolts and studs, used for a strong and tight connection of pipes and pipeline fittings, for connecting them to machines, apparatuses and tanks, for connecting shafts and other rotating parts (flange connection).

Flanges can also be supplied with a set of mounting parts (stud, nut, gasket)

Production

Slip-on flange according to GOST 33259-15. This standard applies to flanges for valves, fittings and pipelines for pressure to PN 250 MPa.

GOST 12820-80 This standard primarily applies to steel sleep-on welded pipeline flanges and connecting parts, as well as attachment fitting flanges, connecting parts of machines, devices, branch pipes of apparatuses and tanks for nominal pressure Ру from 0,1 2,5 МПа (from 1 25 кгс/см2) and ambient temperature from – 70 °С before + 300 °С.

These pipeline parts are used to connect fittings to pipelines, thus connecting separate sections of pipelines to each other, as well as to connect pipelines to various equipment.
