Pipeline reinforcement is carried out to extend the pipe wall thickness in non-leaking pipe defects. These defects happen on account of exterior corrosion or harm, dents, gouges, fretting or put on at helps, inner corrosion and/ or erosion, manufacturing or fabrication defects. The Goal of pipeline reinforcement is to rebuild and improve the pipe wall thickness in order that the resultant pipe mechanical energy is ample to resist working circumstances.Particularly in industries the place scorching works are usually not simply permitted, the implementation of pipeline reinforcement by way of chilly restore works are helpful within the restore and rehabilitation works of pipelines.Pipeline Knowledge & Working ConditionsBefore finishing up an efficient pipeline rehabilitation and reinforcement work, pipeline information and working circumstances are gathered. These information are reviewed and evaluated beneath worldwide requirements and tips resembling ASME PCC2 and ISO 24817 requirements and necessities, to design an efficient and appropriate pipeline restore and reinforcement answer.Detailed Engineering Calculation and Software Methodology of StatementBased on the pipeline information gathered, the producer would design and supply an in depth engineering calculation and utility approach for the pipeline restore and rehabilitation works. It’s also essential to make sure that the applicator is well-trained to use the pipe restore wrapping merchandise in addition to a web site danger evaluation has been carried out previous to work graduation. Correct Personnel Protecting Tools must be worn and danger mitigating/ lowering steps employed to reduce or keep away from all pointless dangers.Step 1 – Making ready, Cleansing and Roughening of Pipe SurfacePipe floor must be cleaned and ready to minimal normal of St2.5. That is to make sure good bonding between the restore resin with the substrate (pipe floor). The pipe floor profile can also be roughed to satisfy the minimal of 60 microns roughness. As soon as the pipe floor has been cleaned and roughened, pipeline restore and rehabilitation works ought to begin instantly.Step 2 – Rebuilding to make sure Flushing of Pipe SurfaceThe first step in all rehabilitation works is to make sure that all pipe surfaces have been rebuilt in order to make sure floor being flush. The resin or steel putty compound is well-mixed in accordance to producer’s directions and utilized onto the affected surfaces whereas making certain there aren’t any air entrapment. The restore compound is utilized in response to the required coating thickness and restore size laid out in engineering calculation.Step 3 – Pipeline Reinforcement by way of Pipe WrappingThe last step is to pipe restore and reinforcement is wrapping of the reinforcement restore tape. Begin wrapping the reinforcement restore tape over the pipe circumference simply earlier than the defect location. At every spherical of wrapping, wrap the pipe as tightly and evenly as attainable whereas pulling with ample energy. Guarantee there may be 50% overlap to the earlier wrapping layer. Repeat the wrapping based mostly on the Engineering Calculation Report. The wrapping path may be alternated between subsequent layers of wrapping to extend its last mechanical energy.Inspection of Pipeline Restore & Reinforcement WorksInspect the strengthened pipeline for any visible defects. Verify that the restore thickness and size complies with the necessities acknowledged within the Engineering Calculation. Permit the repaired space to be cured for a number of hours and the reinforcement work is accomplished.
