Flange Adaptors are designed to join pipes of various outside diameters with flanged equipment of various drilling tables. Because of the wide range tolerance on OD a Flange Adaptor can connect steel, ductile iron, UPVC, cast iron, asbestos cement and other rigid pipe materials to the mating flange. This eliminates on site guesswork and stock range holdings are optimised.
Moulded, circumferentially ribbed or specially profiled gaskets, generally in EPDM or NBR materials, provide for smooth installation by minimising contact friction. Flange Adaptor Gaskets are designed to provide a leak tight seal across the O.D range per nominal size and still allow for thermal expansion and contraction of the pipe up to 5mm per gasket, facilitated through gasket deformation.
