UAG Kelly Bars

Call for price

Kelly bar is a component of rotary drilling rig which is used when the rig is being used in Kelly drilling configuration. Kelly bars main purpose is to transfer the torque of the rotary drive and crowd pressure of the crown system to the drilling tool. UAG  is manufacturing Kelly Bars in various configuration depending upon machine model, rotating torque and customer demand. Normally Kelly bars made of 2 to 5 tubular sections with drive keys and lock recesses on each section.

There are mainly two types of Kelly Bars

  1.  Interlocking Kelly Bars
  2.  Friction Kelly Bars
Categories: ,

KELLY BARS IDENTIFICATION

Identification number for Kelly bars provides information about Kelly type, Nominal Torque, Outer pipe diameter, No. of Kelly bars sections and Nominal Drilling Depth. In ID No. ‘UAG’ Stands for Universal Augers Gulf, ‘I’ stands for Interlocking, ‘F’ Stands for Friction and ‘K’ Stands for Kelly Bar.

  • UAGFK Torque/Dia./Sections/Depth

INTERLOCKING KELLY BARS

Interlocking Kelly bars are used with rotary rigs for drilling in dense sand & gravel and weak to strong rock. UAG is manufacturing fully lockable Interlocking Kelly Bars with mechanical locking system on each section. Specially selected steel pipes and use of special steel drive keys and locks are the key features of UAG  Kelly bars. Specially designed springs are being used for shock absorbing.

FRICTION KELLY BARS:

Friction Kelly bars are used with rotary rigs for drilling in silt, clay and loose dense sand & gravel. UAG is manufacturing non-lockable friction Kelly Bars with drive keys on each section. Specially selected steel pipes and use of special steel for drive keys are the key features of UAG Kelly bars; specially designed springs are being used for shock absorbing.

    The hydromill module is constituted by a heavy steel frame on which two milling drums and a centrifugal mud pump are mounted. In order to correct the module verticality deviation, 12 independent mobile flaps are positioned on the module surface. Furthermore, a simultaneous or independent tilting plate can be installed as optional for the best verticality correction, especially in case of leaned layers of rock. All Soilmec modules are set with a 2D or 3D sensor developed for the module positioning control, which is managed by the Hydromill DMS. Soilmec has designed all its modules with a rotation system conceived for T-panel execution or for other module orientations. This specific feature gives the possibility to facilitate the job site operations, leading to a reduction in terms of cost and time. The 40 t class module is suggested for medium-high depth projects. Its body length and weight guarantee a high verticality level and panel dimensions up to 3200x1800 mm. The high torque cutting unit (up to 153 kNm) can be installed. The module rotation system is included as a standard

    The demand for diaphragm wall equipment suitable to urban areas and the stringent requirement of verticality make the hydromill Cougar a good and easy option to meet the customer’s needs. The Hose Wheels Design (HWD) is positioned below the cathead so that it can easily follow the hydromill movements with a tensioning and rewinding automatic system. It arises from the need to move simultaneously the hydraulic and bentonite mud circulation hoses to the cutting unit. The SC-100 Cougar is a compact hydromill equipment optimized for urban areas and low transportation weight (max 50 t; 110,000 lb). The DMS (Drilling Mate System), developed by Soilmec and installed on all the products of the range, allows the real-time monitoring of all the operating parameters and of the production process, including a dual-axis positioning sensor (triple-axis version as optional) that controls the geometry of the panel with 2D and 3D graphics print out
