In-Service Welding
In-Service Welding expertise you can trust.
TDW has extensive in-service welding experience and a large library of qualified procedures for a wide range of applications. TDW's specialized in-service welding teams are strategically located around the world to help operators safely execute repairs, modifications and installations on live pipeline systems without unnecessary operational disruption.
Key Features
- Live pipeline repairs and modifications: hot tap and STOPPLE fittings, repair sleeves, structural attachments and weld build-up for carbon and steel applications without the need to adjust flow or operating pressure for most applications.
- Broad asset coverage: pipelines, facility piping, tanks and vessels.
- Variety of service conditions: gas and liquid applications, including sour products, hydrogen, CO2 and ethylene, subject to project-specific engineering review and feasibility assessment.
- Wide operating envelope: high CE, high pressure, high flow and no-flow applications covering thin wall 3.2mm (0.125") and thick wall >31.8mm (1.25").
- Application expertise: large in-service welding procedure library to complete feasibility reviews, thermal analysis, mock-ups and welder qualifications.
Common Applications
A successful pressure-containing repair depends on both the repair system and its installation. TDW's qualified in-service welding teams follow established procedures and quality-control practices developed specifically for live pipeline applications and tailored to the selected repair solution, ensuring every repair is completed safely and consistently.
Before field execution, TDW supports project readiness through engineering feasibility reviews, including thermal analysis, and welding procedure qualification and mock-up testing when needed. TDW also administers in-service welding training and qualifications to ensure personnel are competent and prepared to safely execute work upon arrival on site.
In the field, experienced welding and quality control inspectors are supplied for all projects to supervise and monitor in-service welding activities and ensure adherence to the required procedures and inspection and test plans. Comprehensive turnover packages are provided following project completion.
Project managers are also utilized to help coordinate and track all activities, provide a consistent communications channel and support efficient project execution from start to finish.
