API 7-1 Square or Hexagonal Kelly for Oilfield Drilling

Product Introduction

Kelly is on the top of the drill stem. Kelly is main driver of the whole drill string. It transmits drill stem weight and torsional energy from the rotary table through the drill string to the bit at the bottom of the hole. When assembled with down hole motor and Turbodrill tools, Kelly should bare the stem weight and Reverse torque,it will Measure the depth of a well and provide a circulation channel. Our Kelly consists of a driving part (square or hexagonal), upper joint (LH connection) and lower joint (RH connection).

Square drill kelly are made from AISI 4145H alloy bars that are quenched and tempered full length. A hardness range of 285 to 341 BHM and a minimum impact value of 54 Joules as per ASTM A 370 are maintained one inch bellow the surface at room temperature. To improve resistance to galling, all connections are phosphate-coated with an API thread compond. Each bar used to manufacture kellys has been examined with magnetic partice inspections and ultrsonic inspections.

When ordering please specify:

  • Kelly type (Square or hexagonal).
  • Nominal size and overall length.
  • Upper and lower connection.

Features of Our Square or Hexagonal Kelly

  1. Manufactured from AISI4145H-modified, fully heat-treated alloy steel with a Brinell hardness range of 285-341BHN and a minimum average Charpy impact value of 40ft-Ibs.
  2. Ends and drive section,IDs and connections machined and inspected to API specification.
  3. Ultrasonic inspection is performed on all section.
