When aging plants and facilities have degradation of pipe supports, the consequences can be catastrophic. As springs or rigid supports corrode, coils become fatigued or collapse, the loss of support integrity no longer carries the weight of piping for which it was designed. Lines sag, lose proper slopes and transfer the weight into surrounding equipment and nozzles.
The strain of such weight transfers can induce forces and movements, overstress piping and equipment. Stress corrosion and creep can cause failure of components, induce flow problems and severely impair the working conditions of the systems. Periodic audits of B31.1 Power Piping and associated supports are now part of the Code’s requirements to maintain and effect proper conditions or environs in Power and Process Plants.
Innovative MHT Approach to pipe support Driven by Client Needs
As process equipment ages, energy companies have out of necessity, demanded cost cutting innovation in the approach to inspection and repair work. One such innovation is the evolution of some remarkable abseiling techniques to provide access to the potential trouble spots.
These techniques provide safe and immediate access to difficult or challenging locations, while at the same time they offer additional measurable incentives for facility managers. Utilizing rope access techniques and procedure virtually eliminates the cost associated with scaffolding.
The advantages of using industrial abseiling to help tackle IMR issues have long been recognized off-shore.
Through the use of MHT, a specialist rope access inspection and maintenance company, these advantages are now available to downstream on-shore process facilities.
The advantages are impressive and make a compelling business case for utilizing MHT, here are just a few:
Lower risk exposure numbers across the board. In most cases temporary access platforms (scaffold or other) and their associated costs and hazards are eliminated.
Rapid and efficient
Reduced problem identification / mitigation cycle. This can impact upon reliability and operational safety.
Multi-crafted worker teams mean lower costs. Fewer workers to conduct and sustain a IMR program.
