Universal Steel Drill Pipes with welded connectors are used for oil and gas well workover, removal of paraffin and hydrate plugs, cleaning of tubing string, as well as to geophysical surveys in prospecting and exploration of oil and gas.
Alleviated Steel Drill Papes with welded connectors are used for geophysical surveys in prospecting and exploration of solid minerals.
Light Alloayed Drill Pipes – light alloyed drill pipes of the new generation – significantly exceeds domestic Light Alloayed Drill Pipes with diameter 54 mm and foreign drill pipes of the nipple joint:
Light Alloayed Drill Pipes with diameter 54 mm are made of aluminium alloy and fused among themselves by the steel nipples having cylindrical thread with stabilizing shoulders which enlarge the limit of endurance of the pipe’s thread.
Double Wall Drill Pipes are used in drilling of wells with diameter 84 and 93 mm and depth up to 300 m in soils of II-V drillability classes with seams of soils up to VII drillability class in the fulfilment of all necessary prospecting and geochemical operations, in geological mapping and exploration of deposits of solid minerals.
