Abstract:

An insulated transition spool apparatus for mounting unheading devices to pressure vessels, such as coker vessels, and enabling repetitive operation thereof is disclosed. The apparatus comprises an outer housing, an inner housing that encloses an insulating space between the inner and outer housing, a side feed entry aperture in each housing and a spool adapter flange to facilitate attachment of the spool to the vessel.

Appl. No.:

13/966159

Inventors:

David Walter Reeves - Orinda CA, US

International Classification:

F16L 19/025

US Classification:

277314

Abstract:

A method is provided for forming a gasket for sealing opposing flange surfaces of a pipe having corrosive fluid flowing therethrough. The method comprises defining a gasket profile incorporating a serrated profile core having a flange extending radially inward therefrom. A deformable pillow extends radially inward from the serrated profile core, to define a gasket intermediate portion about the flange, and a gasket inner portion radially inward from the flange. The deformable pillow material and thickness are selected such that upon compression to a thickness no less than the core thickness, the gasket inner portion exhibits a stress level sufficient to preclude corrosive liquid flowing through the pipe from passing radially outward beyond the gasket inner portion, and the gasket intermediate portion exhibits a stress level sufficient to preclude gas and liquid flowing through the pipe from passing radially outward beyond the gasket intermediate portion.
