Discover our high-quality API 7-1 Heavy Weight Drill Pipe designed for efficient oil drilling. Made of durable steel, this drill pipe is a reliable tool for your drilling rig. Available in various sizes, it ensures smooth drilling operations. Contact GPE Oil Machinery Co., Ltd, your trusted drilling equipment supplier.
The API 7-1 Heavy Weight Drill Pipe is a high-quality drilling tool designed for oil drilling applications. Manufactured by GPE Oil Machinery Co., Ltd, this drill pipe is made from AISI 4142H-4145H modified drill collar material, following the SY/T 5146-1997 standard.
This heavy weight drill pipe serves as an intermediate weight pipe, providing a smooth transition from heavy drill collars to lighter drill pipes. With its thick-walled construction, it effectively prevents stress concentration at the top of the drill collars. This feature allows for drilling at higher RPMs, reducing torque and minimizing differential pressure sticking.
Primarily intended for directional drilling, the API 7-1 Heavy Weight Drill Pipe offers excellent flexibility, simplifying directional control and minimizing connection fatigue issues commonly encountered in high angle or horizontal drilling. Its superior durability results in reduced pipe failures and increased drill stem service, making it suitable for both directional and straight-hole applications.
Choose the API 7-1 Heavy Weight Drill Pipe for reliable performance, enhanced drilling efficiency, and improved overall drilling operations.
Welcome to consult, we will provide the most comprehensive technical support!
