Stoody®, an ESAB brand, announced that Stoody HB-64 cored wire has been awarded Fearnley Procter NS-1 Level 2 certification for oil field hardbanding application and reapplication. Stoody HB-64 (60 to 64 Rockwell C hardness) is a tool steel alloy enhanced with niobium carbide for superior performance and crack-free harbanding. Its specially formulated wear resistant alloy composition produces a uniform distribution of small primary metal carbides in a martensitic matrix. Stoody HB-64 provides a weld deposit with a low coefficient of friction to reduce tool joint and casing wear. It shows excellent abrasion resistance under the hardbanding conditions. Stoody HB-64 is approved under NS-1 for new hardbanding applications as well as for reapplication onto itself.
The Stoody HB-64 has already been tested extensively in multiple oil fields, says Guy Chouinard, R&D Engineering Manager, ESAB. It offers better hardbanding performance than most of the well-entrenched global products currently in the market, allowing operators to drill more holes before the pipe tool joint needs resurfacing.
Stoody HB-64 cored wire is available to any customer worldwide and is sold in a 33-lb. (15-kg) wire basket or a 50-lb. (22.7-kg) moisture protected Poly Pak, both in 1/16-in. (1.6 mm) diameter.
The Fearnley Procter NS-1 accreditation program provides oilfield equipment and service companies with an industry-recognized approval program that supplements the requirements of American Petroleum Institute (API) standards and demonstrates superior quality management and performance to offshore and onshore operators.
NS-1 certification also ensures that the welding process and specifications given to the welders in the field allow the product to be applied consistently and effectively, insuring sufficient service life while preserving the well casing, says Chouinard.
Stoody HB-56 cored wire previously achieved NS-1 Level 2 certification. Stoody HB-56 is very casing friendly and approved for new applications or reapplication over itself. Stoody HB-56 produces a crack-free martensitic steel deposit with great wear resistance and excellent weldability.
