Replies are encouraged – discussions are welcome.------------------------------------------- Sinopec Fourth Construction Company, in partnership with the Zhuyi Wood EPC consortium, is responsible for the project related to the process systems and thermal pipeline networks at Tianjin Petrochemical’s Nangang ethylene plant. By leveraging their respective strengths, the two parties work together to enhance their capabilities in prefabrication and assembly during construction, focusing on factory-based prefabrication, modular installation, and standardized production procedures. This approach has led to a successful innovation in the method of constructing pipeline corridors. The company continuously improves the construction organization design and advances modular prefabrication; it has reduced the number of modules to be used from 419 as originally planned to 237. The modules are designed to take full advantage of the existing site conditions and available mechanical equipment, thereby minimizing the workload on the module manufacturing facilities and ensuring that the construction progress meets the overall requirements of the project. At present, the 2C and 4C pipe corridors of the plant-wide process and thermal pipeline network project for the Nangang ethylene plant at Tianjin Petrochemical are under active construction.
The construction of the pipeline network for the ethylene plant in Nangang, Tianjin Petrochemical, as well as the \"prefabricated, modular\" construction approach
The Tianjin Petrochemical Nangang Ethylene plant’s process and thermal pipeline system project adheres to the “six modernization” standards for petrochemical project construction in China, thoroughly implementing the concepts of digitalization, integration, modularization, informatization, and intelligence. It adopts prefabricated + modular construction methods, and places strong emphasis on the six key areas of control: HSE, quality, schedule, cost, contracts, and integrity. The goal is to create a \"model project\" that is delivered to high standards and with high quality.
Through standardized design, centralized procurement, factory-based prefabrication, modular construction, and information-based management, the optimization of various steps is advanced, enabling simultaneous operations of \"one site + N construction sites\": the construction of the civil foundation and the production of concrete components take place simultaneously； Installation of concrete components carried out simultaneously with modular manufacturing ； Corrosion protection, insulation, and the installation of pipes, tray systems, etc. are carried out simultaneously.
For the first time, this project attempted to use non-welded pressure testing plugs, which solved the problem of concealing most of the welds within the modules and increased the degree of completeness in the insulation work. The practical results further demonstrated the advantages of approaches such as centralized module manufacturing, which are part of the \"three synchronizations\" strategy. Through in-depth prefabrication, modular and prefabricated construction, project safety, quality, and schedule are ensured comprehensively and effectively; the standard of civilized construction on site is improved, thereby eliminating problems related to poor quality, outdated methods, and defects. Create a model for modular implementation projects to enhance the quality of Sinopec’s engineering projects and its brand image.
On December 8, the hoisting of the 2C pipeline corridor module for the plant’s process and thermal pipeline network project at Tianjin Petrochemical Nangang Ethylene Plant was completed. To date, the project site has completed the modular installation of pipelines 6#, 5#, 2B, and 2C, as well as the on-site assembly of pipeline 2A, thereby achieving connectivity from 2A to 1C, from 2A to the substation in the front area of the plant, and from 2A to the 110kV substation.
