Customer Case Study | Wuhan Iron and Steel (Group) Corporation

From 2008 to 2012, the coal tar processing system upgrade project at Wuhan Pingmei WISCO Joint Coking Company was a key technological transformation initiative undertaken by the Wuhan Iron and Steel Group Corporation. This project required the procurement of complete sets of air separation equipment—including nitrogen generation units, separators, and dryers—from specialized gas equipment suppliers to support the coking production process and ensure the stable operation of the coal chemical production line. Guangzhou Huilin Air Separation Equipment Co., Ltd., a professional manufacturer of air separation equipment, was selected to supply this complete set of equipment leveraging its strong product technical capabilities and project delivery expertise. The two parties conducted multiple rounds of business negotiations and ultimately established a comprehensive project partnership.

Guangzhou Huilin Company adjusts equipment configurations according to on-site operating conditions and has successfully supplied multiple sets of nitrogen generation units along with complete post-processing equipment systems. In strict compliance with national industrial standards, the company's equipment holds full pressure vessel certification; it provides integrated services encompassing factory dispatch, transportation and delivery, on-site installation guidance, commissioning, and operator training; the company implements a "three-guarantee" policy, offering a 1-year quality warranty and delivering comprehensive technical documentation for the entire equipment set.

Ensuring the successful implementation of technological upgrades: Providing reliable service for complete air separation systems operating under complex coking conditions, meeting the gas supply requirements of coal chemical production, and supporting Wuhan Iron and Steel in completing the upgrade and modernization of its production lines.

End-to-end industrial service capability verification: Comprehensive implementation of full-service solutions covering equipment manufacturing, logistics delivery, on-site technical support, and after-sales operation and maintenance – tailored to the requirements of large-scale heavy-industry state-owned enterprise projects.

Industry Benchmark: Establishing a representative collaboration case for air separation equipment in the steel and coal chemical industries, thereby accumulating extensive service experience across large-scale industrial projects.

The collaboration between Guangzhou Huilin Air Separation Equipment and Wuhan Iron and Steel Group represents a typical case of a private-sector air separation equipment manufacturer providing services for the technological upgrade initiatives of large state-owned enterprises in the steel and coal chemical industries. Despite the adjustments and changes in the project scope, Guangzhou Huilin not only ensured the high quality of its equipment hardware but also provided comprehensive on-site technical support and a robust warranty and after-sales service system. By aligning with the stringent procurement standards and challenging on-site operating conditions inherent in heavy-industry projects, the company successfully delivered the complete set of equipment, setting a benchmark practice for the application of air separation equipment in the steel and coking industries.
