Piping installation for oil transportation
Pipeline laying is divided into ground pipeline laying, which includes surveying, support frames, pipeline transportation and hoisting, pipe welding joint beveling and chamfering fabrication, pipe welding, weld inspection, rust removal and cleaning of the inner and outer walls of the pipeline, protective coating, and subsequent pipeline maintenance, as well as valve supervision.
The underground pipeline project includes excavation of pipeline trenches or drilling of underground pipeline holes, pipeline transportation and hoisting, fabrication of pipe weld joint chamfers, pipe welding, weld inspection, rust removal and cleaning of the inner and outer walls of the pipeline, coating protection, and subsequent pipeline maintenance, as well as valve supervision.
