Henan Shenlong Petroleum Drilling Tools Co., LtdBooth：W2812

Henan Shenlong Petroleum Drilling Tools Co., Ltd. is a leading manufacturer specializing in the production of non-magnetic petroleum drilling tools, located in the Science and Technology Industrial Park of Jiyuan City. Owns a full set of petroleum drilling tool production lines, the main production equipment includes: melting, forging equipment, horizontal lathes, CNC spiral milling machines, gantry milling machines, CNC pipe thread lathes, deep hole boring machines, plasma spray welding equipment, CNC milling marks, wire cutting machine tools, etc. , with well-equipped mechanical performance laboratories, material analysis laboratories, magnetic properties and non-destructive testing devices. The company strives for survival by quality, has a complete quality management system, and has API 7-1, API Q1, NS-1, ISO9001, ISO14001, and GB/T28001 certifications. Our products include non-magnetic drill collars, non-magnetic flex collars, non-magnetic stabilizers, non-magnetic subs, etc., with an annual production capacity of 10,000 pieces. The material is low-carbon high-chromium-manganese alloy steel, which has undergone strict chemical The composition ratio is refined, and it is made through a special heat treatment forging process. The cost performance has far exceeded the similar products currently on the market. In addition to fully meeting the requirements of API SPEC7-1, the non-magnetic products are far higher than the requirements of API standards in terms of mechanical properties and magnetic permeability: (1) Good low magnetic permeability, relatively The magnetic permeability can be controlled below 1005 (standard 101); (2) Excellent mechanical properties, the tensile strength is 10-20% higher than the API specification requirements, and the surface hardness can be controlled between HB285-360, large-scale centralizer products The subcutaneous four-quadrant hardness can also be controlled within this range, and the impact energy can reach more than 100J; (3) After the inner hole and outer surface are treated with special technology, the surface roughness can be increased to more than 16um, and the surface hardness is greater than HB450. Surface wear resistance is greatly improved. The products have been sold well in major domestic oil fields and the top three oil service companies in the world, and are also exported to North America, South America, Europe, the Middle East, and Southeast Asia.
