Pipeline Reinforcement

Pipeline reinforcement is done to growth the pipe wall thickness in non-leaking pipe defects. These defects arise due to outside corrosion or harm, dents, gouges, fretting or wear at supports, inner corrosion and/ or erosion, production or fabrication defects. The Objective of pipeline reinforcement is to rebuild and boom the pipe wall thickness so that the consequent pipe mechanical power is enough to withstand working conditions.

Especially in industries where hot works aren’t without difficulty authorized, the implementation of pipeline reinforcement through bloodless restore works are useful within the repair and rehabilitation works of pipelines.

Pipeline Data & Operating Conditions

Before sporting out an powerful pipeline rehabilitation and reinforcement work, pipeline statistics and running situations are accrued. These facts are reviewed and evaluated under worldwide standards and hints consisting of ASME PCC2 and ISO 24817 requirements and necessities, to layout an powerful and appropriate pipeline repair and reinforcement answer.

Detailed Engineering Calculation and Application Method of Statement

Based on the pipeline statistics accumulated, the manufacturer might layout and provide a detailed engineering calculation and alertness approach for the pipeline restore and rehabilitation works. It is likewise vital to make certain that the applicator is properly-educated to use the pipe restore wrapping merchandise as well as a site threat evaluation has been carried out prior to paintings commencement. Proper Personnel Protective Equipment ought to be worn and hazard mitigating/ decreasing steps hired to limit or keep away from all unnecessary risks.

Step 1 – Preparing, Cleaning and Roughening of Pipe Surface

Pipe surface need to be cleaned and organized to minimal general of St2.5. This is to ensure exact bonding among the restore resin with the substrate (pipe surface). The pipe surface profile is also roughed to meet the minimal of 60 microns roughness. Once the pipe floor has been cleaned and roughened, pipeline repair and rehabilitation works ought to commence immediately.

Step 2 – Rebuilding to make sure Flushing of Pipe Surface

The first step in all rehabilitation works is to make certain that all pipe surfaces had been rebuilt with a purpose to ensure floor being flush. The resin or metallic putty compound is nicely-mixed in accordance to manufacturer’s commands and applied onto the affected surfaces even as ensuring there aren’t any air entrapment. The repair compound is applied in step with the desired coating thickness and repair duration specified in engineering calculation.

Step three – Pipeline Reinforcement through Pipe Wrapping

The very last step is to pipe restore and reinforcement is wrapping of the reinforcement repair tape. Start wrapping the reinforcement repair tape over the pipe circumference just before the illness region. At each round of wrapping, wrap the pipe as tightly and flippantly as feasible whilst pulling with sufficient energy. Ensure there is 50% overlap to the preceding wrapping layer. Repeat the wrapping based totally at the Engineering Calculation Report. The wrapping path may be alternated among subsequent layers of wrapping to increase its final mechanical power.
