Detailed Product Description

Integral heavy weight drill pipes are manufactured from AISI 4142H-4145H modified drill collar material according to API SPEC7-1, thick-walled pipe called integral heavy weight drill pipe was developed to provid a gradual transition from the heavy weight drill collars to the relatively light weight drill pipe. This intermediate weight pipe has a wall thickness of approximately, and it helps prevent stress concentration at the top of the drill collars. It also allows you to drill at higher pms, reducing torque and differential pressure sticking
