Product Description

API Non-Magnetic Drill Collar Size 2.7/8" by GPE Oil Machinery Co., Ltd is a high-quality, non-magnetic drill collar designed for well drilling. It meets API 7-1 standards and is available in a spiral or heavier spiral design. Perfect for drilling equipment, this drill collar is durable and reliable.

Product Description: Drill Collars

The drill collars offered by GPE Oil Machinery Co., Ltd are constructed using modified AISI 4145H chromium molybdenum alloy steel, ensuring exceptional durability and performance. These drill collar bars undergo a full-length heat treatment process and are water quenched to obtain ASTM A-370 mechanical properties, guaranteeing superior strength and reliability.

For quality assurance, all drill collars come with comprehensive mechanical and chemical mill test certifications. These certifications confirm a hardness range of 285 to 341 BHN and an impressive impact value of 40 ft.-lbs. at room temperature, located one inch below the surface. This ensures the drill collars can withstand demanding drilling operations with ease.

To ensure precise and accurate bores, each drill collar bar is trepanned and then drifted to API specifications. This meticulous process guarantees close tolerance bores, allowing for seamless integration with other drilling equipment.

The drill collar bars feature an "as rolled" surface finish, which retains the original mill finish. This finish not only enhances the aesthetic appeal of the drill collars but also contributes to their overall durability and longevity.

Choose GPE Oil Machinery Co., Ltd for drill collars that combine exceptional strength, reliability, and precision. Experience the difference in performance and efficiency with our top-quality drill collars.
