API Chinese Best Sale Drilling Hexagonal Kelly Pipe 4145 H

Hexagon Kelly

The hexagonal kelly is made of AISI 4145H alloy rods and has been hardened and tempered for the full length. At room temperature, the bellows are kept in the hardness range of 285 to 341 BHM, with A minimum impact value of 54 joules according to ASTM A 370. To improve wear resistance, all connections are phosphate coated with API threaded assemblies. Each bar used to make the Kelly was examined by magnetic particles and ultrasound.
