Traps for multiple launches
Traps for multiple launches Product ID: PE-03-01-03
These units are designed to allow the sequential launching of pigs and spheres. In conjunction with release fingers and/or coordinated valve operation the launch process can be controlled remotely enabling traps to be installed on unmanned platforms and facilities. This enables sequential launching to take place without having to repeatedly de-pressurise and re- pressurise after each launching.…
Moisture Oil Monitor
Moisture Oil Monitor Product ID: INS-06-01-03
Water contamination in oil based fluids can cause numerous problems such as loss of revenue, additive depletion, oil oxidation, corrosion, reduced lubricating film thickness, accelerated component wear rates, microbiological growth, reduction of dielectric strength and loss of power as an example . These problems can be prevented by online monitoring , so that problems can be averted in time.
Rapid Opening Closure
Rapid Opening Closure Product ID: PE-03-02-02
Closures are pressure retaining structures designed to provide access to pipelines and pressure vessels. to provide fast access to pipelines and pressure vessels. Quick to open or close in just 30 secondstwo simple movements, removal of vent plug and the 25º turn of the handle is all that is required to rapidly release the closure.…
