How Often does Hardbanding Need to be Applied?

Depending on drilling conditions and hardbanding performance, hardbanding will have to be reapplied anywhere from several weeks to many months of service. Hardband re-application is a costly and time consuming process which usually involves transporting drill string components to inspection or other facilities that are capable of hardbanding operations. Mobile hardbanding units may also be deployed to or near drilling operations for on-site application. Use of these machines depends on the availability or supply of units offered in any given area.
