Mechanical Engineering for Process Plants | SL-TECH

At Changzhou Sanli Tech International Trade Co., Ltd., mechanical engineering for process plants forms the structural and operational backbone of every project we undertake. We recognize that in the demanding environments of chemical manufacturing—from high-temperature Ethylene Oxide (EO) reactions to high-pressure Polymerization processes—the integrity of every pipe, vessel, and rotating machine is paramount. Our mechanical engineering team specializes in the design, selection, and specification of critical equipment for a vast range of essential chemical industries. For a plant like the Bisphenol-A Plant, our mechanical engineering expertise ensures that the reactors, crystallizers, and dryers are designed to withstand the corrosive nature of the process media while maintaining precise thermal control. We leverage our collaboration with the Institute of Process Engineering of the Chinese Academy of Sciences to stay at the forefront of materials science, ensuring that our equipment specifications for new technologies like the Polysulfone Plant are optimal. Our services cover all aspects, from the design of complex piping systems that handle multiphase flows in a Methylamines Plant to the selection of high-efficiency compressors and pumps for a Methanol Plant. We provide detailed engineering drawings, stress analysis reports, and 3D modeling to ensure that every component is precisely fabricated and easily maintainable, reducing downtime and extending the plant’s operational lifespan.
