Removing The Hazards Of In-Field Butt Welding

The PREMIER approach is the application of logic - rather than trying to provide ideal welding conditions in the field the process is reversed and pipes are welded under ideal conditions in the factory, tested, then taken to the field. Field butt welding is always a troublesome business requiring close supervision, protection from the elements, a generating set and has low productivity. If there is a failure during testing, the repair and rewelding are particularly complicated.
