Premium Threads

Superior Connections

Premium connections are typically designed to have a stronger fatigue resistance and enhanced sealing properties without compromising the ease of make up and break out. These properties allow for higher forces and pressure ratings during drilling operations.

We are licensed to machine Tenaris DSTJ, TPS TS 4/6/8, Drillpipe Master DS50, Benoit BTS6, and Grant Prideco Hi-Torque, GPDS, XT, XT-F and TurboTorque premium connections.

Hard Facing

Best-in-class Application

We offer a complete range of hard-facing to suit all drilling conditions. Through continuous improvement, we have leveraged on our experience and technical know-how to develop expertise on wear resistance and characteristics, as well as matrix hardness. Extensive in-house research has resulted in our best-in-class application process; the increased reliability in bonding is proven by track records on the field.

HF 1000: Crushed Tungsten Carbides are fused together within a tough polycrystalline matrix of nickel. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF 2000: Geothermal Dressing: trapezoidal tungsten carbide inserts are held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage – ideal for high deviation drilling in abrasive formations.

HF 3000: Metal Powder spray is used to fuse the tungsten carbides. This spray deposit is ideal for abrasive formations. Recommended for non-magnetic stabilizers

HF 5000: Flexicoy Technodur: Fused tungsten carbide in a nickel chrome boron matrix designed for oxy-acetylene torch application. Flexicoy has pure nickel core surrounded by fused tungsten carbide and alloy elements for the matrix.

HF 6000: Flexicoy Technosphere & Diamond Tungsten Carbide Inserts: Diamond inserts and tungsten carbide inserts are set in a powder spray deposit – ideal for very abrasive formations.

Surface Engineering

Embracing Technology

OSS is an ARNCO certified applicator for 100XT, 150XT, 300XT and 350XT for hardbanding solutions. These are applied using a metal arc, inert gas shielded consumable electrode process. Granular tungsten carbide particles are fed automatically into the molten weld pool to obtain a uniform distribution and maximize wear resistance.

Precisely controlled pre-heat and post-heat conditions ensure that only fully-metallurgical bonded hardbanding overlays of optimum integrity are applied. The deposit is made flush to + 1/32 above the O.D. of the collar.

Our research & development partners employ Plasma Transferred Arc (PTA) welding and Laser Cladding technologies to provide even more wear resistance for your specific requirements.

Cutting-edge technology is applied to extend your tools’ service life – the coatings and overlays impart greatly improved performance of the desired characteristics such as wear resistance, impact resistance, sliding wear, corrosion protection, friction modification and other specific electrical properties.
