API 7-1 Square and Hexagonal Kelly for Oilfield Drilling
Product Introduction
Kellys is the driving section of wohole drill stem. Kelly is available with square kelly and hexagonal kelly. Our kelly pipes are manufactured strictly from API Spec7-1 and SY/T6509-2000 standard.
Straightness of the kelly is very crucial in the manufacturing process, thus straightness inspections are carried out before, during and after each machining operation. All milling processes are performed on specially designed rigid Kelly mills to ensure tight tolerances and high quality drive sections.
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.
