It mainly produces cold-drawn steel pipes of various specifications with an outer diameter of 8- -219mm, a wall thickness of 0.8- -20mm, and a length of 12m or more, and can also be processed with supplied materials.

Ten new precision rolling precision steel pipe units, mainly producing outer diameter: C 10- -219mm, wall thickness: C 1-30mm precision pipe, 20# precision steel pipe, 45# precision steel pipe, GLR15 bearing steel pipe, Q355B precision steel pipe The company has modern standard workshops, advanced precision cold-rolled pipe production lines, and perfect physical and chemical testing equipment. The salient features are: 1. The cold-rolled precision steel pipe has high tolerance and dimensional accuracy, and the product accuracy is controlled to 0.05mm; the smoothness is good; the inner and outer surfaces have no oxide layer, and the inner wall is clean. 2. The comprehensive performance of cold-rolled precision steel pipe is excellent, it can withstand high pressure, cold bending, flaring, flattening does not crack, does not wrinkle skin, and can be processed for various complex deformations and mechanical processing. 3. The promotion and application of precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save machining hours, improve production capacity and material utilization, and at the same time help improve product quality and reduce cost.

The products are suitable for: bridges, steel structures, large airport construction, plant construction, automobiles, motorcycles, electric power, machinery, hydraulic accessories, bearings, pneumatic components, oil cylinders, coal mines, transportation, boiler equipment, pipelines, engineering and other fields .
We have our own R&D team, developed the intellectual property rights of key technologies, and launched a large number of series of new products. The R&D department cooperates with a number of research institutes and colleges to hire senior steel researchers and pipeline industry consultants. At the same time, the quality inspection department of our factory cooperates with the quality inspection bureau to share talents, testing equipment and technical resources.
