Drilling Pipe

Modern drilling requires more efficient activities (faster drilling speed, higher drilling quality, suitability for special drilling environments, and safer drilling). As the main drilling tool, the performance and quality of the drill pipe are pivotal to drilling ability, efficiency, quality, and drilling safety.
Hilong is committed to the technological innovation of drill pipes. It constantly designs and develops high-end drill pipe products to meet the requirements of modern efficient drilling, and with exceptional quality and excellent product performance, it contributes to meeting the needs from clients and modern drilling projects.

Excellent steel purity, metallurgical quality, microstructure uniformity, impact toughness and fatigue resistance.
·Adopt optimized Miu and Miu-R designs, combined with a special stable upsetting process, which improves the fatigue resistance on upsetting end of the drill pipe.
·Using MES and ERP systems, it can realize comprehensive information management of the entire process from order-to-shipment, including the entire manufacturing process, inspection and test acceptance, and product traceability.
·Pipe body 100% FLUT (longitudinal, transverse, oblique ultrasonic testing + ultrasonic thickness measurement) + 100% pipe end MPI (or UT), drill pipe tool joint 100%UT+100%MPI, welding zone 100%UT+100% MPI.

·Integration: drill pipe tool joint manufacturing, upsetting, heat treatment and friction welding, hardbanding wire production and application, internal coating material production and application.
