Chongqing Meitong Mining Machinery Manufacturing Co., Ltd., a domestic professional manufacturer of drill pipes and drilling tools, is located in the Luohuang Industrial Park, Chongqing. Its products are widely used in various fields such as geology, coal mines, chemical industry, and construction engineering, and have received high praise from users. In a modern industrial plant covering nearly 10,000 square meters, the company owns specialized production equipment for drill pipes, including 200-ton, 400-ton, and 600-ton automatic pipe end thickening equipment, CNC friction welding machines, imported CNC machining centers, and an integrated heat treatment production line for drill pipes. With complete production processing techniques, a strict quality management system, and technical guidance from senior experts, the company ensures that every product's technical indicators, interchangeability, and usage safety are fully guaranteed. Relying on its excellent technical talent team, the company continuously innovates and improves, striving to be the technological leader in the industry. After three years of technological research and development, the company successfully developed a unique integrated drill pipe processing technology. The produced drill pipes feature high strength and good straightness, effectively avoiding issues common with traditional friction welded drill pipes, such as poor straightness, insufficient strength, and easy breakage at welds. This achievement has led to the acquisition of multiple national patents. Once launched, the series of products were warmly welcomed by a wide range of users, who subsequently abandoned the use of traditional friction welded drill pipes. Currently, the company continues to conduct new technological research and explore advanced production processes. These new technologies and processes will be applied to the production and technical services for customers.
