Spiral gaskets

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]

The spiral-wound type furnished with a sohd metallic ring on the outside to hmit gasket compression provides protection against blowout when used with raised facing. [Pg.956]

Spiral-wound gaskets are safer than fiber gaskets because, if the bolts work loose or are not tightened correctly, the leak rate is much lower. [Pg.2267]

Low Leak Rate If friendly equipment does leak, it does so at a low rate, which is easy to stop or control. Examples already mentioned are spiral-wound gaskets, tubular reactors, and vapor phase reactors. [Pg.2268]

The inlet flange shall be of the weldneck type with raised face designed in accordance with ASME BPV Code Section VIII. The flange shall be axial entry with a surface finish of 150-250 micro inches. The gasket shall be of the spiral-wound metal type with a seating stress of 10,000 psi. [Pg.310]

The leaks that lead to explosions in compressor houses are often not from a compressor but from other equipment, such as pipe joints. One such leak occurred because a spiral-wound gasket had been replaced by a compressed asbestos fiber one, probably as temporary measure, seven years earlier. Once installed, it was replaced by a similar one during subsequent maintenance [30]. [Pg.69]

The size and frequency of leaks can be reduced by using spiral-wound gaskets in place of compressed asbestos fiber ones. Screwed joints should not be used. [Pg.176]

Radially split casings shall have metal-to-metal fits, with confined controlled compression gaskets, such as an O-ring or a spiral wound type. [Pg.21]

Note For pumps with flange and pressure ratings in excess of the minimum values in 2.2.2, the gland stud size and circle may increase. Larger studs shall be furnished only if required to meet the stress requirements of Section VIII or Section II of the ASME Code, or to sufficiently compress spiral wound gaskets in accordance with manufacturer s specifications.

Unless otherwise specified, the gland plate to seal chamber seal shall be a fluoroelastomer O-ring for services below 150°C (300°F). For temperatures 150°C (300°F) and above or when specified, graphite-filled austenitic stainless steel spiral wound gaskets shall be used. The gasket shall be capable of withstanding the full (uncooled) temperature of the pumped fluid. [Pg.135]
