Taiyuan Tongze Heavy Industry Co., Ltd. was established in August 2001, with registered capitalof 51.7 million yuan. The headquarters and R&D center are located in Shanxi Transformation and Comprehensive Reform Demonstration Zone. It belongs to the equipment manufacturing industry. It is a high-tech private enterprise that develops seamless steel pipe hot rolling and extrusion equipments, special defense equipments and precision molds and has general contracting, system integration and international trade business. It owns mature practical experience in R&D, design, manufacturing, installation and trial production of large-scale seamless steel pipe production line project general contracting.


Tongze is a high-tech enterprise, a national-level technology innovation demonstration enterprise, a national-level intellectual property advantage enterprise. The company has a state-level enterprise technology center with an academician work station and a postdoctoral research station.


The leading products developed by Tongze include: continuous rolling steel pipe production line, radial forging mill, seamless steel pipe rotary expansion production line, stainless steel extrusion production line, large diameter thick-wall seamless steel pipe punching-drawing production line. The seamless steel pipe hot-rolling and extrusion forming equipment developed by Tongze can produce seamless steel pipes with diameters from Φ32mm to Φ1500mm and wall thicknesses from 3.2mm to 200mm.


Tongze adheres to the development strategies of “Talent-oriented, innovation-oriented, and advocating dedication” cultivates and forges innovative talents and promote development through innovation.

After more than ten years of independent innovation and hard work,  Tongze takes the lead in realizing the localization and industrialization of major complete technical equipment for continuous rolling mills. The two-roll and three-roll continuous rolling mills developed by Tongze have reached the international advanced level. The Φ114mm two-roll continuous rolling pipe production line won the first prize of Taiyuan Science and Technology Progress Award, the Φ250mm two-roll continuous rolling pipe production line won the first prize of Shanxi Science and Technology Progress, and the Φ366mm three-roll continuous rolling mill units was recognized as a national key new product. Exported Φ180mm continuous rolling pipe unit to India first realized the breakthrough of “zero” export of significant seamless steel pipe equipment of China. China's first 36MN stainless steel hot extrusion pipe production line developed by Tongze was identified as a national key new product. In 2018, the first homemade TMH20/15MN radial forging mill with our own intellectual property rights was successfully tested and put into production.


Tongze’s products have a large coverage and high market share.
