RNW PACIFIC ERW BI PIPES
Pipes produced in single lengths by high frequency induction welding and afterwards cut into desired lengths, having a longitudinal butt joint wherein coalescence is produced by the heat obtained from resistance of the pipe to the flow of electric current in a circuit of which the pipe is a part, and by the application of pressure.
