Thermoflex® spoolable pipe can also be pulled through existing steel pipe.
Inserting Thermoflex® pipe in existing pipelines can dramatically reduce installation costs by eliminating the cost associated with trenching. Using this technique, the Thermoflex® sizing is dependent upon the restrictions in the steel pipe. It is advisable to run a pig with wireline to clear any restrictions before proceeding with Thermoflex® installation.
The pull through rehabilitation process makes it easy for Thermoflex® piping to be inserted and pulled through long distances inside of existing pipelines.
Pipe rehabilitation with Thermoflex® piping can be performed with minimal disruption to ongoing operations.
The benefits of using the pull through rehabilitation method include:
Reduced costs vs. installing new steel line
Shorter lead time and less downtime
Long term corrosion resistance
Miniminal environmental disturbance
