Hdd operation methods

Drilling operations are performed on both sides of the river called Rig Side and Pipe Side, such as drilling rig, power pack system, power generator, drilling mud construction and pumping system, and storage and control ponds for cabin or control room and a set Drilling rods (pipes approximately 9.5 meters long that are threaded on both sides and screwed behind each other to send the drill into the soil and guide the drill in the drilling path.) It is located with a suitable location and on the other side, the main pipes of the water supply plan are welded on the rollers as long as the path. This area is called the Pipe Side area.

The welded pipe in the mentioned project is 500 or 600 meters long after radiography and the joints are insulated with polyurethane. Also, before starting the pipe laying operation, it is necessary to perform hydrostatic test for leakage and electrical coating test to confirm the correctness of the insulation.
