Changzhou Sanli Tech International Trade Co., Ltd. provides comprehensive basic and detailed engineering design services, forming the technical backbone of every chemical plant project we undertake. Our engineering design process is structured in two key phases to ensure thoroughness and precision. The basic engineering design phase, also known as front-end engineering design (FEED), establishes the project’s fundamental framework. For a complex plant like a POM (Polyformaldehyde) Plant, this includes developing process flow diagrams (PFDs), preparing the overall plant layout, defining major equipment specifications, and generating a preliminary cost estimate and project schedule. This phase is critical for defining the project scope and securing project financing. The detailed engineering design phase then builds upon this foundation, producing all the detailed documentation required for construction. This includes piping and instrumentation diagrams (P&IDs), detailed piping isometrics, civil and structural drawings, electrical and instrumentation loop diagrams, and a complete set of construction specifications. Our engineering teams use advanced 3D modeling tools to create a detailed virtual model of the plant, enabling precise material take-offs, clash detection, and optimized design. By executing both basic and detailed engineering design in-house, we ensure consistency, quality, and a seamless transition from concept to construction.
