Flange faces

The following factors must be considered when selecting a gasket material  [Pg.861]

The process conditions pressure, temperature, corrosive nature of the process fluid. [Pg.861]

Whether repeated assembly and disassembly of the joint is required. [Pg.861]

Flanges are also classified according to the type of flange face used. There are two basic types  [Pg.861]

The finish of flange facings varies with the manufacturer. For raised-face or male mating surfaces the finish usually consists of a continuous spiral groove formed by a round-nosed tool or a V tool (serrated finish). Female surfaces are smooth-finished (i.e., without definite tool markings). Other finishes are concentric-grooved, lapped, or mirror (cold-water). The latter two are usually for application without gaskets. [Pg.954]

Flange face sheet gaskets at pipe joints. [Pg.34]

Don t use flange bolts to unite misaligned piping to the pump. This damages the flange faces and stresses the pump easing (Figure 17-18). [Pg.246]

Dimensional and runout inspections to determine the extent of deformation to bores, turns, flange faces, and fit areas. [Pg.206]

Piping shall be in accordance with the requirements of ASME B3 1.3. Flange faces shall be finished in accordance with ANSI 646.1... [Pg.306]

The full faces of flanges never really touch due to the gaskets or rings that cause the seal. The space between the two flange faces is a. cry... [Pg.462]

Flange face areas experience stagnant conditions. Additionally, some gasket materials, such as asbestos fiber, contain leachable chloride ions. This creates crevice and stress corrosion cracking problems on sealing surfaces. Where necessary, flange faces that are at risk can be overlaid with nickel-based alloys. Alternatively, compressed asbestos fiber gaskets shrouded in PTFE may be used. [Pg.904]

Where Hg = gasket reaction (pressure force), = nG(2b)mPi Ht = pressure force on the flange face = H — Hd,... [Pg.864]

Distance of weld toe from flange face should be 2 mm (1/i6 in.) or greater... [Pg.52]

GENERAL NOTE The weld deposit connecting the pipe end to the flange face at the I.D. shall not result in a weld buildup or undercut of the flange face surface. [Pg.52]

Flange facings shall be suitable for the intended service and for the gaskets and bolting employed. [Pg.104]

Flange rating and type of facing is specified in data sheets. Flange facing finish shall be minimum per ASME B16.5. [Pg.274]
