Import Drill Piperotary Clamp Device — Buy in Bulk from Supplier in China

The Drill Piperotary Clamp Device is a wellhead-mounted tool designed to apply torque to drill pipes when the kelly is not engaged, enabling forward or reverse rotation without disconnecting the drill string. It accommodates pipe diameters from 2 3/8 inch to 5 inch and has a rated torque capacity of 60 kN.m. The device is engineered for direct installation on wellhead or casing threads, eliminating the need to pull the drill string during make-up or break-out operations.

It is constructed from high-strength alloy steel with surface hardening to resist wear under high-torque conditions. The clamping mechanism uses a hydraulic or mechanical actuation system, depending on model variant, and is compatible with API 5DP and ISO 11960 standard drill pipe dimensions. Typical industry tolerance for jaw alignment is ±0.5 mm to prevent pipe slippage or damage during rotation. This device is commonly used in onshore and offshore drilling rigs where time savings and operational continuity are critical.

Buyers include drilling contractors operating in Southeast Asia, the Middle East, and North Africa, where extended wellbore operations demand efficient pipe handling. The device is shipped in a steel crate with foam padding and includes mounting hardware. Standard trade terms are FOB Nantong Port, with lead times of 4 to 6 weeks. Minimum order quantity is typically one unit, but bulk discounts apply for orders of five or more.

Jiangsu Rudong Lianfeng Petroleum Machinery Co., Ltd. is based in Rudong County, Jiangsu Province, China, with its manufacturing facility located on Huaihe Road in the Economic Development Zone. The company specializes in downhole tools and wellhead equipment for drilling operations. Its listing shows a harbor-tier trust score and no recorded response rate, indicating it may operate with a focus on bulk orders rather than rapid inquiry handling.

The supplier does not provide details on workforce size, annual production volume, or client list. There is no mention of ISO certification, third-party inspection reports, or export history. The product description is technically accurate and matches known industry designs, suggesting operational competence, but buyers should request test certificates and material reports before finalizing orders.
