Hunan Shuangma New Material Technology Co., Ltd. is a high-tech enterprise specializing in the development, design, and manufacturing of complete pipeline equipment, as well as the research and development, design, manufacturing, marketing, and after-sales service of new coal mine gas pipelines. The annual production capacity of gas pipelines is over 450000 meters. The company is located in the Changzhutan Economic Integration Development Zone, which has development potential among the six central provinces, with convenient transportation conditions and broad development space. At present, the company has 265 registered employees, including 69 engineering and technical personnel, 18 holding senior professional titles, and 32 holding intermediate professional titles.

Through years of dedicated research and the use of new materials and structural mechanics theory, we have successfully developed a high-tech new type of gas pipeline - the covered spiral welded composite steel pipe for coal mine gas drainage. The new gas pipeline solves the problem of coal mining enterprises not having ideal gas pipelines to choose from for many years, and eliminates gas accidents from the source of gas extraction pipelines. The company has obtained national invention patents for new pipelines and pipeline production equipment (patent numbers ZL201010288533.6 and ZL200810228610.1) and multiple utility model patents. The covered spiral welded composite steel pipe used for gas drainage in coal mines not only inherits the various excellent characteristics of traditional gas pipelines, but also makes up for the defects of existing gas pipelines. It is an ideal gas pipeline to replace traditional steel pipes, plastic pipes, and reinforced composite pipes. The promotion and use of new gas pipelines will undoubtedly bring significant results to coal mining enterprises in terms of safety production, efficient extraction, reduction of comprehensive cost per ton of coal, and reduction of labor intensity for workers.
While inheriting and promoting the various excellent characteristics of coated spiral welded composite steel pipes, the company has successively developed coated spiral welded corrugated composite steel pipes and stainless steel spiral welded corrugated steel pipes for coal mine gas drainage, and has obtained multiple patent certificates, which are highly praised by users. This series of new gas pipelines provides more options for coal mining enterprises to further improve production safety and reduce comprehensive costs.

We adhere to the principle of "value sharing and win-win cooperation" and sincerely look forward to working with you!
