MRC is an interlocking clamp system to reinforce the corroded pipe wall. Pipeline restoration by MRC clamps withstand original operating pressure and meets expected operating life. Optional length is the main advantage of MRC clamps, as during installation, contractor will adjust the clamping area based on corroded length. So, there is no need to have clamps with different lengths. This modular feature brings considerable saving for installation time and cost, especially in large projects with several installation zones. MRC can be also used as Bend Limiter for critical sections of sub-sea pipelines.
After pipeline intelligent pigging, restoration of wall thin spots on pipeline is the main function to prevent costly leakage or rupture of pipeline, in addition to productivity and profitability of the network. Injectable annulus on MRC clamps integrate the clamp with pipeline through a elastomer filler, which acts as barrier to transfer the loads from the pipeline to the MRC clamps body.
