Strengthening of Pipelines with Post-Tensioning System
In cases where pipeline segments in need repair cannot be shut down, reinforcing with CTech-LLC®’s TensaPipe™ External Post-Tensioning System is an effective solution to return the deteriorated pipe’s ability to withstand internal pressures.
The TensaPipe™ External Post-Tensioning System utilizes steel tendons helically wrapped around the exterior of an existing pipe.A TensaPipe™ tendon consists of high-strength steel strand, encapsulated by extruded plastic for corrosion protection, and an anchorage assembly. The strand is wrapped around the exterior circumference of host pipe and stressed at the anchorage utilizing hydraulic jacks.
CTech-llc®’s Tensapipe™ external post-tensioning system with its wide variety types of anchorage and strands and rapid installation processis ideally suited for localized repairs of damaged pipe while pipeline remains in service.
