Product Description: Drill Collars


The drill collars offered by GPE Oil Machinery Co., Ltd are made of modified AISI 4145H chromium molybdenum alloy steel. These drill collar bars undergo full-length heat treatment and water quenching to obtain ASTM A-370 mechanical properties, ensuring superior performance and durability.


With every drill collar, we provide full mechanical and chemical mill test certifications, guaranteeing a hardness range of 285 to 341 BHN and an impact value of 40 ft.-lbs. at room temperature, one inch below the surface. These certifications assure you of the high quality and reliability of our products.


To ensure close tolerance bores, all drill collar bars are trepanned and then drifted to API specifications. This meticulous process guarantees precision and accuracy in every drill collar we offer. The bar surface finish is "as rolled," retaining the original mill finish for a professional and polished appearance.


Invest in our drill collars for your drilling operations and experience the exceptional performance and reliability they offer. Trust GPE Oil Machinery Co., Ltd for top-quality products that meet your drilling needs.
