Price On request

Description

Light alloy boring pipes with pipe joints are designated for drilling wells mainly by core method with the use of diamond and hard-alloy crown bits at high rpm during exploration and survey for solid mineral resources and water at controlled (multi-well) drilling and correction of hole direction, exploration surveys, in construction.

Boring depth: up to 1200 m.
