Abstract
Structure supporting apparatus which for a particular nominal size can be interchangeably sealingly clamped and centered between bolted flanges of varying pressure rating and design standard. The apparatus includes at least one support member having opposite parallel sides for sealingly engaging the seating surfaces of the flanges, a centrally positioned opening extending through the member and through the sides thereof for positioning structure supported thereby in alignment with the flow passageways in the flanges, the periphery of the support member being substantially square shape and including a pair of spaced apart recesses disposed in each of the four sides forming the substantially square shaped periphery thereof.
Claims12
Structure supporting apparatus which can be interchangeably sealingly clamped and centered between bolted flanges of varying pressure rating and design standard, said flanges including complementary flow passageways therein and annular seating surfaces thereon comprising at least one support member having opposite sides for sealingly engaging the seating surfaces of said flanges, a centrally positioned opening extending through said member and through said opposite sides thereof for positioning structure supported by said member in alignment with the flow passageways in said flanges and having a substantially square shaped periphery including a pair of spaced apart recesses disposed in each of the four sides forming the substantially square shaped periphery.
Structure supporting apparatus which can be interchangeably sealingly clamped and centered between bolted flanges of varying pressure rating and design standard, the flanges including complementary flow passageways therein and annular seating surfaces thereon comprising a pair of identical support members adapted to have said structure supported therebetween, each having a flat side for sealingly engaging a seating surface of one of said flanges, a centrally positioned opening extending therethrough for positioning said structure supported by said support members in alignment with and across the flow passageways in said flanges and a substantially square shaped periphery including a pair of spaced apart recesses disposed in each of the four sides forming said substantially square shaped periphery.
Pressure relief apparatus which can be interchangeably sealingly clamped and centered between bolted flanges of varying pressure rating and design standard, the flanges including complementary flow passageways therein and annular seating surfaces thereon comprising:
- a rupture disk having a flange portion adapted to be clamped between support members;
- and
- a pair of complementary support members for clamping said rupture disk therebetween, each having flat parallel sides for sealingly engaging the seating surfaces of said flanges and the flange portion of said rupture disk, each having a centrally positioned opening extending through said support member and through the flat parallel sides thereof for positioning a portion of said rupture disk clamped by said support members in alignment with and across the flow passageways in said flanges and each having a substantially square shaped periphery including a pair of spaced apart rounded recesses in each of the four sides forming said substantially square shaped periphery.
