Hardbanding Solutions by Postle Industries has developed crack-free, casing friendly Duraband® NC hardbanding alloy for the most reliable wear protection for drill pipe applications without damaging the casing. It is 100% rebuildable and is Fearnley Procter NS-1™ Certified for application on new tool joints, as well as, re-application over itself and most competitive products. The cost of hardband re-application can be very expensive if the previous hardband must be removed before re-application can proceed. Close to 80% of the total cost of a re-application is removal of the previous hardbanding, application of mild steel as a buildup, and subsequent machining of the mild steel to prepare the tool joint for the application of the hardband. Duraband® NC can substantially reduce the cost of re-application since it can be applied over most previous hardbanding, without the need for removal. However, there are certain ones that they cannot go over. If this is the case, a complete re-application is required, which includes previous hardband removal, mild steel build-up and machining. It should be noted that once this procedure has been completed, any subsequent re-application of Duraband® NC should not include removal of the hardbanding and any associated procedures. Postle Industries is committed to developing crack-free, casing friendly alloys and welding techniques to meet the industry’s needs. Our focus isn't just on laboratory, marketing, production and delivery skills, but also on keeping a pulse on the oil/gas and drilling industries through participation in such organizations as the API Casing Wear Group, CAODC, IADC and DEA, as well as the American Welding Society. Only through this close and dedicated effort are we able to address the pressing issues and trends of the day and the future. For more information, contact [email protected].
