Top Drive Saver Sub
Top drive subs are a pin-by-pin sub that is made up to the top drive, they serve as the sacrificial element between the drill string and the top drive. This saves on costly repair to the top drive by allowing multiple connections to be made up and broke out using the sub rather than the top drive itself.
-
The top drive sub can easily be repaired or replaced in the event the lower pin threads become galled or damaged. These tools are manufactured from selected bars of alloy steel, heat treated to provide the strength and toughness required to carry the entire weight of the drill string. Top drive saver subs are manufactured to customers request, based on API requirements. All of our drill stem subs are manufactured in accordance with API specifications.
Features and Benefits
-
Heat treated to meet or exceed API specifications for drill pipe tool joint mechanical properties
-
Precision machined API connections, with proprietary connections available machined by licensed vendors
-
Serialized for complete material traceability

Wear Sub
During drilling operation, serious wear often takes place between drill pipes and casings. The wear sub is typically placed above the drill bit. It is designed to withstand the abrasive forces encountered during drilling, such as formations with high rock hardness or high levels of drill bit vibration.¥ 0.00Details
-
Lifting Sub
Lifting sub is the special tools for lifting of the drill tools in petroleum, natural gas industry and geologic exploration. With their multifunctional design, lifting subs are instrumental in a wide array of lifting operations, including equipment installation, well servicing, and rigging applications.¥ 0.00Details
-
Crossover Sub
Crossover sub is a short sub assembly used to enable two components with different thread types or sizes to be connected. Also it can be used to protect other tooling in drill stem (called saver sub) or be used to deliver outgoing air to the bit face just above the bit (called bit sub).¥ 0.00Details

Universal Bottom Hole Orientation Sub
The Universal Bottom Hole Orientation (UBHO) Sub is used in a directional drilling BHA, and it is manufactured from high quality AISI 4145-modified fully heat-treated alloy steel or non-magnetic material like P530, P550 to provide a non-magnetic environment for drill string.¥ 0.00Details
