DURMAT Hard-banding Wires The advent of horizontal drilling and other advancements has created new challenges that leave the majority of traditional hard-banding products obsolete. DURUM s commitment with investing in new technological advances, as they relate to material science and process application has resulted in several recent developments that have demonstrated superior performance in terms of reducing casing wear, increasing wear resistance and improving consistency in harsh/aggressive drilling environments. A few of the primary factors include: DURUM s production plant in Germany is ISO 9001 certified. All materials such as Flux Cored Wires, Tungsten Carbide Powders, Stick Electrodes, Oxy-Acetylene Rods, PTA and HVOF Powders are analysed and tested before shipping. Our laboratory is equipped with hardness tester, particle size analyser (Microtrac), Spectromax for analysing chemistry and elements in applied materials, G65 Abrasion Wear Test machine, different kind of microscopy. The addition of elements such as Niobium, Molybdenum, Titanium, Cobalt, Titanium or Vanadium are beneficial by forming the respective carbides that reduce the coefficient of friction; The formation of microstructures that exhibit amazing stability during high temperature conditions resulting from friction; The use of alloying elements that improve the thermal conductivity to minimize typical coating failures (i.e., heat checking). Our involvement in hard-banding started in 1976 when Tungsten Carbide was the most popular wear resistant material for overlaying tool joints and other parts. At the 1991 SPE IADC Drilling Conference held in Amsterdam, 11-14 March 1991 DURUM presented a paper called: Evaluation of New Tool Joint Hard-facing Material for Extended Connection Life and Minimum Casing Wear. In between 1999 to 2001 several casing friendly wires had been approved and tested by Maurer and successfully approved by major oil companies. DURUM has been a front-runner in materials research and application. Several patents validate our on-going research and development program for Wear Protection Materials and 2 2012 DURUM VERSCHLEISS-SCHUTZ GMBH / DURMAT INC.
