Import Drill Collar — Buy in Bulk from Supplier in China

Sgeil Trading Co., Ltd. supplies a drill collar manufactured from modified AISI 4145H chromium‑molybdenum alloy steel, designed to maintain stability and balance during demanding drilling operations. The alloy’s composition provides high tensile strength and durability, essential for deep‑well and geothermal projects. Precision engineering ensures the collar fits standard top‑drive systems while offering enhanced corrosion resistance for extended service life.

Typical tensile strength for this alloy exceeds 620 MPa, and hardness is generally around 30 HRC, matching the performance expectations of heavy‑weight drill collars. The supplier offers custom lengths and diameters; industry‑standard outer diameters range from 100 mm to 150 mm (4‑6 in) and lengths from 0.6 m to 1.8 m are common. These specifications align with the API 7‑1 class commonly applied to downhole weight‑on‑bit tools.

The collars are essential for oil and gas drilling, especially in deep‑well, geothermal and high‑stress environments where tool balance is critical. Drilling contractors and equipment integrators source them for new well programmes and rig upgrades. Sgeil Trading provides MOQ flexibility and ships on FOB or CIF terms, with robust packaging to protect the heavy units. Buyers should request ISO certification copies and confirm the exact dimensions needed for their rigs before finalising any order.
