3 Tips for Welding Repairs on In-Service Pipelines - North welded pipe for low pressure service

The ultrasound testing (UT) of a pipes wall thickness is critical for in-service repairs. If the wall thickness in the weld area is too thin, the operator must extend the sleeve area on the pipe. The ability to safely weld the pipe also depends on the pressure the line is running; pressure is often lowered for repair work. 3 Tips for Welding Repairs on In-Service Pipelines - North welded pipe for low pressure serviceThe ultrasound testing (UT) of a pipes wall thickness is critical for in-service repairs.
