摘要： The invention proposes a method of modernizing a flexible conduit line (50), wherein the modernization method comprises the following steps performed in at least one end fittings joint (11, 12, 13), namely, removing a check valve (16) or a plug (17) from at least one outlet port (15) of an end fitting (111, 121, 131), removing a check valve (16′) or a plug (17′) of at least one outlet port (15′) of an adjacent end fitting (111′, 121′, 131′), installing a tubular line (90) in an external position to provide fluid communication between said at least one outlet port (15) of the end fitting (111, 121, 131) and said at least one outlet port (15′) of the adjacent end fitting (111′, 121′, 131′). The invention further proposes an end fittings joint (12) comprising an end fitting (121) and an adjacent end fitting (121′), the end fittings joint (12) comprising a tubular line (90) positioned externally to the end fittings (121, 121′) in order to establish fluid communication between at least one outlet port (15) of the end fitting and at least one outlet port (15′) of the adjacent end fitting (121′). The invention further proposes an interconnection module (80) connectable to a first end fitting (121) suitable to be installed in a first flexible conduit segment (52) and connectable to a second end fitting (121′) suitable to be installed in a second flexible conduit segment (53). The interconnection module (80) further comprises a tubular line (90) in an external position configured to provide fluid communication between at least one outlet port (15) of the first end fitting (121) and at least one port (15′) of the second end fitting (121′).

摘要： This bleeder guard is used for blinding pipe flanges in refineries, chemical plants, and other fluid processing plants joined in many places by flanged joints. The bleeder guard is an elongated rod, having a first end with a threaded surface and a second end with a smooth surface. The bleeder guard preferably is a smooth elongated rod of uniform diameter. The elongated rod typically has a cylindrical shape.

摘要： A pipe repair apparatus is provided. The pipe repair apparatus includes a cap. The cap includes a cylinder shape having a front edge forming an opening into the cap, a rear edge forming an opening into the cap, and at least a first side edge and a second side edge. The cap may further include a cap flange formed at the front edge having a first bend in a direction towards a central longitudinal axis of the cap and a second bend in a direction away from the central longitudinal axis of the cap. The cap is sized to fit over a pipe so that the first side edge overlaps the second side edge. A clamp secures the cap to the pipe.

摘要： A clamp assembly for temporarily applying compressive force to a flange connection assembly, such as a bolted pipe flange. Frame members are pivotally attached to interconnecting linkage members to form an elongate assembly having joinable ends. When installed around the circumference of a flange connection assembly, interchangeable cuff members removably attached to the frame members apply compressive forces to a flange connection assembly in order to facilitate a fluid-pressure seal.
