Proplug J-Tube plugs can be passive or active, with staggered split design where required.
Pressure retaining capability and design life to suit specific project requirements.
Passive J-Tube Seals
Pushed into position, the sealing discs deform to hold the plug in place. The discs must be flipped to allow retrieval. Disc size is optimised for a maximum removal pull load.
Active J-Tube Seals
Based upon the compression plug design, polyurethane seals are actuated by applying torque to a series of energizing nuts. An oversized flange with urethane protection provides a positive stop during installation.
Annulus Sealing Plugs (Pipe in Pipe)
Manufactured to seal between a carrier and casing pipe. Split design to allow assembly over pre-existing structures. May be passive or active and utilise high grade polyurethane seals. Optional high temperature seals and grout injection ports.
