Product Description

Drill Pipe

Drill pipe is a major drill component which connects rotary system, hoisting system, circulation system with drill collar and bit. Through it the rotary table drives the bit rotation, hook drives bit up and down and drill fluid flows to the well bottom forming circle to make the bit brooks rock and roaches continuous drilling.
Products features:
High quality raw material and advanced heat treatment make the products higher hardness and toughness. Especially it has higher low temperature toughness.
Smoother and longer upset taper length and high performance pipe extends the drill pipe^, s service life.
Meet or exceed API SPEC 5DP, API SPEC 7-2, and API RP 7G requirement.
Adopt complete advanced testing method and strict quality control to ensure the high quality and stable performance products.
Holding advanced technology, high-end product R & D capabilities and senior technical workers, we can provide customer special requirement products.
