Api 7-1 Spiral Non Magnetic Drill Collar
The Api 7-1 Spiral Non Magnetic Drill Collar from Dongying Lake Petroleum Technology Co., Ltd is a precision-engineered component for oil and gas drilling operations, available in sizes from 3-1/8 to 11 inches. It is manufactured from AISI 4145H modified steel, trepanned and drifted to meet API Spec 7-1 standards, with full-length heat treatment ensuring mechanical properties comply with or exceed the specification. Serial numbers are die-stamped on each bar body for complete traceability from raw material to finished product.
Surface finishes include the standard as-rolled condition, with optional phosphate coating or copper plating on connections to enhance corrosion resistance. The drill collars undergo rigorous inspection, including visual dimensional checks and ultrasonic testing across the entire body, while cold-rolled thread roots and elevator recess upper radii improve fatigue life by minimizing crack initiation. Optional slip and elevator recesses are machined to API Spec 7-1 guidelines to enhance handling efficiency and safety.
These non-magnetic drill collars are used in directional drilling and measurement-while-drilling (MWD) applications where magnetic interference must be minimized. Buyers typically include oilfield service companies and drilling contractors sourcing reliable, API-compliant equipment for onshore and offshore rigs. The supplier offers steel, cast steel, and plastic thread protectors as standard accessories, with custom sizes available on request.
