Case Study

TDW Offering: Repair Solution

Technology: PETROSLEEVE® or Type C-sleeve (compression)

Project Location: Texas

Pipeline challenge detected

The client identified SCC (Stress Corrosion Cracking) and DSAW (Double Submerged Arc Weld) defects in the pipeline. If left unrepaired, these defects constitute a threat of pipeline failure under typical operating conditions. These defects appeared across 13 sites on a 36-inch diameter pipeline operating at ~820 psig. Traditional repair methods using Type B sleeves could have potentially taken up to five weeks.

Goal for Repair Solutions team

The objective going into the jobsites was to restore pipeline integrity quickly and safely, minimize downtime and disruption to gas flow and ensure regulatory compliance. 

Solution for job:

• 22 PETROSLEEVE® installations were completed in four total days.
• Utilized three welding crews for simultaneous operations. 

Tool application:

• NPS 36x1" thick x 36" long.
• Material: A516-70.
