Method of preventing dangerous annulus pressure rise

摘要

Casing coupling portion which is modified include one or more containers for the modular burst disk assembly. Is held by a snap ring or threads, this burst disk assembly is sealed by integral o- ring seal or retaining screws and mountain. At a pressure specified by the user, before the integrity of the outer casing is threatened by annulus pressure is trapped and, this disk is damaged. This design, burst disk assembly is possible before shipment of the pipe, or field assemblies.
