Duraband® NC from Hardbanding Solutions is a 100% crack-free hardband that provides maximum protection of the tool joint and casing as well as workstring completion tubing (also referred to as hardbanding completion tubing or tubebanding). Its microstructure consists of a hard, but tough tool steel matrix with a high volume of tightly packed micro-constituents. This chemistry ensures a non-cracking hard band with excellent wear resistance in open hole drilling as well as being casing friendly.

The rebuilding of tong spaces on a tool joint box or pin is quite similar to traditional hardbanding applications. Careful attention to preheating procedures and temperatures as well as slow cooling during postwelding procedures is critical. Particular attention should be given to inspection of services for cracks using MPI methods.The procedure below outlines the basic requirements to successfully rebuild tong spaces with Postalloy® Tool Joint BU-MCG. Some adjustments will be required to accommodate various diameters of tool joints.

Postalloy Tuffband NC is a high hardness hardband that may be used by itself for casing friendly hardband applications or used as a weld matrix with Tungsten Carbide (WC) when casing protection is not a factor.
