Description

Downhole Drilling Tools - API Square Kelly drill pipe and hexagonal kelly

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. Kelly consists of a driving part (square or hexagonal), upper joint (LH connection) and lower joint (RH connection).

Kelly is the drive part of whole drill stem, it has two types, square kelly and hexagonal kelly and all of them are manufactured comfort to API Spec7-1 and SY/T6509-2000 criterion.

Our Square& Hexagonal kelly are made from AISI 4145H modified alloy bars that are quenched and tempered full length. After such heat treatment, its brinell hardness can reach 285-341. Kelly's end, drive cross-section and joint are all processed and tested comform to API criterion.
