Mechanical Engineering for Process Plants | SL-TECH

The mechanical engineering expertise at Changzhou Sanli Tech International Trade Co., Ltd. is a cornerstone of our ability to deliver reliable and efficient process plants. We approach each project with a deep understanding of the mechanical challenges inherent in chemical production, providing solutions that ensure safety, longevity, and operational excellence. For facilities like the UHMWPE (Ultra High Molecular Polyethylene) Plant, our mechanical engineers focus on the unique demands of handling high-viscosity polymers, designing specialized reactors, extruders, and material handling systems that can manage the physical properties of the product without degradation. In contrast, for a high-purity Methylal (Pressure Swing Distillation Process) Plant, the emphasis is on designing distillation columns and internals that achieve the required separation efficiency while minimizing pressure drop. Our team is proficient in using advanced engineering software to perform finite element analysis (FEA) on pressure vessels for an Ethylene Oxide (EO) Plant and to model fluid flow in the piping networks of a Sulfuric Acid Plant. We also prioritize the selection of materials that can withstand the specific corrosive and erosive conditions of each process, whether it’s handling strong acids or volatile organics. By integrating this deep mechanical expertise into our overall turnkey delivery model, we ensure that the plants we build are not only technically sound but also mechanically robust and built for decades of reliable service.
