Import Drill Collar — Buy in Bulk from Supplier in China

The drill collar offered by Xian Landrill Oil Tools Co., Ltd is a downhole component designed for oil and gas drilling operations. It is manufactured in accordance with API 7, API 7‑1 and SY/T standards, ensuring compliance with recognised industry specifications. The body is forged from AISI 4145H steel or optional non‑magnetic alloy, providing the strength required for high‑pressure environments. A slick external profile reduces hydraulic drag and improves weight‑on‑bit efficiency.

Typical drill collars of this class have an outer diameter of 76 mm and an inner diameter of 68 mm, with length ranging from 300 mm to 1800 mm, which matches the dimensions commonly used in rotary‑cone drilling rigs. The material hardness is usually between 45‑50 HRC, and tensile strength exceeds 1200 MPa, values that are standard for high‑grade drill‑pipe components. These specifications are complemented by a standard API thread (API 8‑1) and a pressure rating of up to 200 MPa, allowing safe operation in both onshore and offshore wells.

The collars are suited for drilling rigs in oil and gas exploration, geothermal projects and mining shafts where reliable weight distribution is critical. Xian Landrill supplies the product with robust wooden crate or steel pallet packaging and accepts L/C or T/T payment terms, but exact MOQ and lead time should be confirmed directly with the supplier. Importers are advised to request the mill test report and any applicable certification documents to verify compliance before placing an order.

Xian Landrill Oil Tools Co., Ltd is located in Shaanxi province, China, at Room 508, Suntek International No. 6Th Suntek Road, Hi‑Tech Zone, Xian 710075. The supplier is classified as an imported‑tier vendor with a harbour trust tier, although the listed response rate is 0.00 percent and no average response time is recorded, indicating that communication timelines should be verified directly with the sales team.

The company lists drill collars as part of its oilfield equipment portfolio, emphasizing compliance with API 7, API 7‑1 and SY/T standards. It offers flexible minimum order quantities and standard trade terms such as L/C and T/T, but does not provide detailed information on certifications beyond those mentioned in the product description.
