Ethylene Glycol Plant Steel Structures, Ordos (Dalat) Pipe-Racks & Process Frames Zhonghengfeng Construction Group

Zhong Heng Feng Construction Group engineered and erected steel pipe-racks and process frames for Inner Mongolia Rongxin Chemical’s ethylene glycol complex in Ordos (Dalat), including DMO synthesis/purification units and ethylene-glycol separation frameworks. The project integrates high-reliability steel structures with process, utility, and maintenance systems.

Located in Sanshang Liang Industrial Park, Dalat Banner, Ordos City, the Inner Mongolia Rongxin Chemical Complex is a circular-economy project producing ethylene glycol and related products. Zhong Heng Feng Construction Group Co., Ltd. delivered heavy industrial steelworks for multi-level pipe-racks, equipment platforms, and separation/purification frames—coordinated with process, piping, and electrical systems to ensure safe, continuous operation.
