Main Features of Hardbanding:

BoTn is famous for a complete series of high performance anti-wear & friction-reduction hardbanding wires, BoTn1000, Botn3000 and Botn5000. The tests results prove that the materials have perfect performance of anti-wear and friction-reduction under downhole conditions.

BoTn1000: Sufficient hardness (HRC58-62) and good anti-wear property which can triple drill tool joint life. It can be spplied to surfacing welding for new & used tool joint, heavy weight drill pipe and various downhole instruments surface.

BoTn3000: sufficient hardness (HRC58-62) and good anti-wear property which can protect drill pipe to the maximum extent. Perfect friction-reduction properly that can reduce the torque of the drilling string.

BoTn5000: excellent friction-reduction property, which can reduce the casing wear. Tight combination between Botn5000 hardbanding and base metal of tool joint, no spalling, no chipping.

 

Main Features of Internal Coating:

- TC-2000 is epoxy-phenolic material, which can be used in a wide range of temperatures and PH conditions.

TC-2000SS is epoxy-phenolic coating, for use in high temperature and pressure environment of natural gas wells with high content of H 2S and CO 2.

TC2000P is an epoxy-novolac powder coating, which can be used in gas production environments containing H 2S and CO2 with higher temperature(400 )and higher pressure conditions.

Other Types of Drill Pipe We Can Do:

 

KINGWELL Sour Service Drill Pipe

KINGWELL Sour Service Drill Pipe is a type of propriety product with capability of resist to hydrogen sulfide stress corrosion to facilitate the drilling activities in H2S environment.

Size range: Kingwell sour service drill pipe is available for drill pipe ranging in size from 2 3/8 to 6 5/8 inches.

 

KINGWELL Aluminum Alloy Drill Pipe

KINGWELL Aluminum Alloy Drill Pipe features low specific weight, high flexibility, good corrosion resistance, thus more suitable for extra deep well, horizontal well, high corrosive medium well, directional well and other wells with complicated conditions.

 

KINGWELL Efficient Cuttings Bed Clean Drill Tool
