Description: Kelly Cock valve is an effective manually operated ball type valve for the drill stem. It located within the drill string that allow for free-passage of drilling fluid without pressure loss and are specifically designed for effective control of blow outs and/or mud loss control. The kelly valve is divided into upper kelly cock valve and lower kelly cock valve. The upper kelly cock is connected between lower end of swivel and upper end of kelly; the lower kelly valve is connected between lower end of kelly saver sub. The kelly valve can be opened on or closed off by only turning the special operating wrench at 90° according to indicating direction. During drilling operation, both upper and lower Kelly cocks should be connected to prevent accident during drilling operation.

Drilling Tool Drill Kelly LUHAI provides square Kelly and hexagonal Kelly which is manufactured strictly according to API Spec7-1 and SY/T6509-2000 standard. Description & Specification Size: full range from 2-1/2 to 6 Material: AISI 4145H alloy steel Standard: API SPEC 7-1,SY/T6509-2000.
Kelly Valves-Drill Pipe Safety Valve Kelly Valve/Drill Pipe Safety Valve is a full opening valve that provides positive pressure control of the fluids in the drill string. Product Description Kelly Valve/Drill Pipe Safety Valve is a full opening valve that provides positive pressure control of the fluids in the drill string. These valves can be used as a drill pipe safety valve or upper kelly valve to control blowout pressures, or as a lower kelly valve to prevent loss of drilling fluid when the kelly is disconnected. Product Features The valve seals in both directions with metal to metal seals. Available in 10,000 psi working pressure as standard, 15,000 psi working pressure is available in certain sizes upon request. The valve uses a hexagon socket on the operating stem and has positive stops in the open and closed positions. With the exception of the standard body, all components are manufactured from materials meeting the requirements of the National Association of Corrosion Engineers (NACE) Standard MR0175 "Standard Material Requirements, Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment"How to Order Specify: Outer Diameter Connections *Other sizes and connections available upon request.
Kelly Valve also named Kelly Cock/Drill Pipe Safety Valve allowing free passage of drilling fluid without pressure loss. The valve can be used as a dill pipe safety valve or upper Kelly valve to control blowout pressures, or as a lower Kelly Valve to prevent loss of drilling fluid when the Kelly is disconnected. It has a pressure rating of 5,000psi or 10,000psi or 15,000psi

Kelly bar is the key part of a drilling machine, and its quality directly affects the performance of the whole machine. The main purpose of kelly bar is to transfer the torque of rotary drive and crowd pressure of the crowd system to the drilling tool. Based on the rich manufacturing experience and by absorbing the advanced technology both at home and abroad, we can produce first-class kelly bar which can be compared favorably with the imported ones. The features of UNIMATE kelly bar are as follows: Adopt the advanced technology of 6-key design in the world and standard modular design. Equipped with advanced processing facilities, workmanship and manufacturing equipments, UNIMATE kelly bar enjoys a low weight, high strength, high straightness of single bar, thinner tube, smaller inter-tube distance and good abrasion resistance. The raw materials are either imported from Germany like the high abrasion resistance materials, or from Chinese top manufacturer such as the seamless steel tube with alloy. All the tubes made in China are specially made seamless alloy tube, which guarantees the accuracy of the sizes, location, physical properties and easy welding. The small-diameter tubes undergo reheat treatment. The friction kelly bar can be used under full torque. All the outer keys have undergone special heat treatment; therefore, they possess higher hardness, higher flexibility and excellent welding properties, which provide higher abrasion resistance to the keys. There are mainly two types of Kelly bars: 1-Interlocking Kelly Bar 2-Friction Kelly Bar Friction Kelly Bar Friction Kelly bars are used with piling rigs for drilling in silt, clay and less dense sand and gravel. The Friction Kelly bars manufactured by Unimate are un-lockable with drive keys on each section. Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose. Steel pallet, wooden case.
