  • Non-magnetic Drill Collars
    We produce non-magnetic drill collars (slick and spiral) and non-magnetic bearing drill pipes. The material we use can be P550 or P530. The largest size we can produce is 9-1/2" (241.3mm)....

  • Non-magnetic drill collars are manufactured from chrome manganese, low carbon obtained by combining a proprietary chemical analysis and a rotary hammer process. The material is resistant to stress corrosion cracking, with high machine ability and no tendency to galling.
    1. When the magnetic field strength is 1×105/4πA/m, the relative permeability μr should be less than 1.010.

    1. Magnetic induction intensity gradient(△B)of the non-magnetic drilling tools apart from 100mm arbitrarily along the hole should not be more than 0.05μT.

  • Kellys
    We can produce square kellys and hexagonal kellys. The largest size we can produce is 6" (152.4mm). The longest size we can produce is 54ft (16.46m)....

  • Our kellys are made from 4145H modified alloy bars that are quenched and tempered on full length. A hardness range of 285 to 341 BHN and a minimum impact value of 40ft-Ibs are maintained one inch below the surface at room temperature. All ends and center drive sections are trepanned to provide true bores. They are drifted to API specifications, and all connections are machined. Kellys are stamped with API SPEC 7-1 monogram, where applicable.
