Reinforced “olive” – coupling pipes are longitudinally welded or seamless pipes which have big wall thickness and are hot galvanized. Connections are cylindrical threaded and provided with coupling.
The coupling is obtained from galvanized seamless pipe, it is cylindrical threaded and has a particular olive shape that makes it very strong.
These pipes are used in 6 mt lengths bars usually for submersible pumps that have to be placed very deep, where it is not possible to lay flanged riser pipes, and in 2/3 meters lengths bars for pile-driver drillings.
