Import Api Standard Drill Collar — Buy in Bulk from Supplier in China

The API Standard Drill Collar from Shanxi Weigao Petroleum Drilling Tools Co., Ltd. is a heavy-weight tubular designed to apply force to the drill bit in oil and gas, mining, and construction drilling. Supplied in sizes from 3 inches to 9 inches, it is available in spiral or slick configurations to suit different borehole conditions and drilling requirements. The API connection ensures compatibility with standard rig equipment, while the robust alloy steel construction provides the durability needed for deep or directional drilling operations.

Material composition typically includes high-grade alloy steel, with heat treatment applied to enhance mechanical properties such as tensile strength and resistance to fatigue. Spiral designs reduce wall contact and improve hole cleaning, while slick collars are preferred for vertical drilling where stability is critical. The product meets API Spec 7-1 standards for dimensional and performance criteria, with typical outer diameter tolerances held to ±0.5% and inner diameter machined to ensure smooth fluid flow.

Primarily used by oilfield contractors and exploration companies, these collars are critical for maintaining hole direction and stability in challenging formations. Buyers should confirm thread type (e.g., NC38, NC46, NC50) and connection specifications to match existing rig setups. Packaging is typically wooden crates or steel skids for international shipment, with FOB or CIF terms available. Lead times and MOQs are supplier-specific and should be verified directly.
