IN-SERVICE WELDING

In-service welding is a welding activity that is done directly onto the pipeline while the production is online. NJ Petroniaga has performed multiple in-service welding for our hot-tap fitting and pipe sleeve installation. Most of these weldings are done on flammable gas pipelines. We are proud to say that we have zero incidents on in-service welding.
