Kellys are manufactured with one of two drive configurations, square or hexagonal. Square kellys are furnished as forged or machined in the drive section. Hexagonal or fully machined square kellys are machined from full length quenched and tempered round bars.
Description: A drill bit is a device attached to the end of the drill string that breaks apart, cuts or crushes the rock formations when drilling a wellbore, such as those drilled to extract water, gas, or oil.
Description: Horizontal Hole openers, also known as HDD reamer, are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. HDD is used when trenching and excavating is not practical. This drilling technology allows for a steerable trenchless way to drill underground. There are three stages, the first stage is to drill a small diameter pilot hole. The second stage is enlarge the hole with a larger diameter cutting tool called an HDD Reamer, Rock Reamer or Hole Opener. The third stage is inserting the casing pipe or other product into the enlarged hole.

Description: The IBOP is a non-return valve (check valve), also called Gray Valve or BVR, is a back pressure valve used in the drill string to prevent the well from flowing uncontrollably up the drill string. It is used to hold the tool open therefore it is possible to stab the valve while the fluid is flowing through the drill pipe. With the IBOP valve installed in the drill string, it allows you to strip in hole without mud flowing through the drill sting. The IBOP valve should not be used for shut the well in while tripping.
Description: Accumulator unit for BOP stacks is a very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. It consists of remote control system, drillers panel, air cable (except electrical type), pipe rack (electrical warming system available for cold area), high pressure manifold, protection room, etc. Accumulator unit is designed, manufactured and inspected in accordance with API Spec. 16D and it can be divided into two types: Electrical type FKDQ series and Pneumatic type FKQ series.

Description: Ram type BOPs are field proven products that are designed for a variety of operations from workovers to high pressure, critical service operations for land drilling and subsea service. It consists of the BOP body, bonnet, hydraulic cylinder assembly, operating piston, ram change cylinder, ram opening/closing piston, locking screw, ram assembly, sealing parts etc. Top, bottom and outlet connection dimensions conform to Specification for Drilling through Equipment API Spec 16A. Made up of the high-strength and high-tenacity alloy steel, the pressure-bearing parts (like BOP body, bonnet etc.) are formed through external refining and proper heat treatment, preventing the harmful chemical components and nonmetallic inclusion strictly from materials and ensuring BOP to be safe and reliable. The body ram chamber adopts the long runway to reduce stress concentration. Both the bonnet switch and ram switch are driven by the hydraulic pressure and adopts the same one oil line. The bonnet employs the same one oil line and operation to open and close the ram. Moreover, the bonnet employs the same one oil line and operation to close and open the ram.
