Drill Pipe

Shanghai Hilong Drill Pipe Co., Ltd. is based on the Shanghai Hilong Petroleum Tubular Goods Research Institute this powerful development platform, using thickening technology with the international advanced level of technology, heat treatment technology, friction welding technology and world-class production and testing equipment, not only to provide cover for all users API standard and conventional drill steel grade, but with its own research and development capability to manufacture a variety of special products to meet growing customer demand.
With the difficulty of oil and gas exploration and production growing and the performance requirements of deep wells, horizontal wells, extended reach wells, sulfur environment and low temperature environment to drill pipes increasing, API standards drill pipes can’t meet it. Therefore, Hilong has developed a super high-strength drill pipe (HWDP), sour service drill pipe (HWDP), arctic service drill pipe, efficient cuttings bed clean drill pipe which clear inclined wells and horizontal wells debris deposited , offshore casing landing pipe which meets the requirements of high performance marine drilling, and so on a series of special drill pipe. Among them, the Hilong double-shouldered super high torque special buckle series (HLDS, HLIDS, HLMT, HLST) provides a convenient connection to the drill pipe with higher mechanical properties and drilling operations.
