Custom-Designed Process Equipment Manufacturers in India
Mathesis Engineers specializes in the custom design, mechanical engineering, and precision fabrication of non-standard, highly specialized process equipment tailored specifically to unique process chemistry, extreme metallurgy, and complex plant layouts.
Many advanced chemical, pharmaceutical, and high-purity processes require non-standard equipment geometries, exotic alloy metallurgy, complex internal heating/cooling coils, or custom drive systems that off-the-shelf catalog vendors cannot supply.
With over 44 years of mechanical design expertise, Mathesis Engineers collaborates directly with process technology licensors and plant engineers to manufacture custom pressure vessels, special reactors, clad vessels, heat exchangers, and multi-unit process skids.
Our thermal and mechanical engineering team performs 3D CAD modeling, finite element analysis (FEA), computational fluid dynamics (CFD), and ASME Section VIII Div 1 code stress calculations tailored to your exact process parameters.
We fabricate custom units utilizing specialized welding procedures (WPS/PQR) for exotic alloys (Hastelloy, Titanium, Inconel, Nickel, Monel, Duplex) followed by 100% NDE testing and factory inspection.
