Technowrap™ carbon steel tee live leak seal repair in Galveston, Texas

Challenges

• Live leak seal repair

Benefits

• Cost-effective

• Quick repair

• No shutdown required

Scope

A full-service terminal and processing facility requested ICR to perform a live leak seal at its multi-modal transfer facility in Galveston, Texas, USA. The repair was required on a 3” carbon steel tee on a wastewater line that had suffered a through-wall defect caused by internal and external corrosion.

Following the live leak seal, ICR was requested to complete an engineered composite repair solution with a design life of 10 years to restore the integrity of the line. The scope included an engineered design calculation, complete with a design sketch, materials, and personnel to execute the repair.

Solution

After ensuring the leak was effectively sealed, the piping was surface prepped for the Technowrap™ application using a bristle blasting method, which ensured a cleanliness level of ST3 and a minimum surface roughness of 40 microns.

Following surface preparation, ICR personnel applied two of the 10 required layers before conducting a successful leak seal test. The remaining eight layers were then installed using a combination of our 2K cloth type and low-temperature (LT) resin.

Result

The leak seal and Technowrap™ repair successfully restored the line’s integrity, while a 10-year design life was met.

As ICR quickly completed both the live leak seal and the Technowrap™ repair, the project remained cost-effective and timely for our customer. This project further demonstrates the effectiveness of Technowrap™ in supporting urgent repairs.
