Product solutions
Casing Pipes line the borehole, stabilize the borehole and protect the soil and groundwater layers from external influences – they are the structural backbone of every drilling operation.
Tubing pipes safely transport extracted media such as oil or gas from the wellbore to the surface and are directly responsible for the production flow.
Accessories such as couplings, pup joints, or crossovers connect different pipe diameters or threaded connections and are manufactured directly in Kindberg.
Line pipes are used for the safe transport of liquids and gases over long distances and comply with international standards such as API 5L, ASTM, and ASME.
