Vacuum Flange Standards

Specifies dimensions for fixed and rotatable bolted flanges for use in low, medium and high vacuum systems within the range of 10 mm to 1000 mm nominal bore. Flange No. designation is used and preferred sizes identified. Flange Nos. 50 and below will accommodate future...

This document specifies the dimensions of fixed or rotatable bolted knife-edge flanges used in vacuum systems for pressures ranging from atmospheric to as low as 10−11 Pa.

This document specifies the dimensions of non-knife-edge flanges and collars used in vacuum technology. The dimensions ensure interchangeability between bolted, clamped and rotatable flanges: a) whether the assembly be homogeneous (for example, bolted flanges or clamped...

1.1 This specification2 covers quenched and tempered vacuum-treated carbon and alloy steel forgings for pressure vessels such as those used in reactor systems. Specifically, it covers forgings for vessel closures, shells, flanges, tube sheets, rings, heads, and similar parts. 1.2 All...

This document specifies the dimensions of the clamped-type quick-release couplings used in vacuum technology, as well as those of the O-rings and their carriers associated with these couplings, used to ensure vacuum tightness. NOTE The dimensions retained for the coupling diameter...

1.1 This specification covers a group of common requirements that shall apply to steel flanges, forged fittings, valves, and parts for piping applications under any of the following individual product specifications: Title of Specification ASTM Designation Forgings, Carbon Steel, for Piping...

This specification covers several grades of carbon and low alloy steel forged or ring-rolled flanges, forged fittings and valves for low-temperature service. The steel specimens shall be melt processed using open-hearth, basic oxygen, electric furnace or vacuum-induction melting. A...

This document specifies mounting dimensions for vacuum pipeline fittings (elbows, tees and crosses) of knife-edge flanges for nominal bores from 16 mm to 200 mm.

1.1 This specification covers hot isostatically-pressed, powder metallurgy, stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts made to specified dimensions or to dimensional standards, such as in ASME specification B16.5....

1.1 This specification covers hot isostatically-pressed, powder metallurgy, alloy steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts made to specified dimensions or to dimensional standards, such as in ASME Specification B16.5. 1.2...

This document specifies mounting dimensions for vacuum pipeline fittings (elbows, tees and crosses) of non knife-edge flange for nominal bores from 10 mm to 250 mm of the R5 series.

1.1 This specification covers pressure consolidated powder metallurgy nickel alloy pipe flanges, fittings, valves, and parts intended for general corrosion or heat-resisting service. 1.1.1 UNS N06625 products are furnished in two grades of different heat-treated conditions: 1.1.1.1 Grade 1...
