FACILITIES
With over 60,000 sq.ft., Prosysco’s two fully equipped facilities have the varied ability to fabricate complete process systems.
The first facility stands as a dedicated hub for fabrication, machining, and polishing. On the parallel front, our second facility, designed as an entirely self-contained unit tailored specifically for the fabrication of high-purity piping. Furthermore, this facility functions as a seamless platform for the assembly of integrated process skids, alongside facilitating the conduction of Factory Acceptance Testing (FAT) activities.

WElding
All orbital and manual welding completed during fabrication of equipment is performed by certified welders according to WPS (Welding Procedure Specifications). In parallel, our Quality Control team creates Weld Logs, Welding Control and Material Control packages that comply with Prosysco’s standard procedures.
polishing
Our team of exceptionally skilled Technicians undertakes the task of meticulously polishing and buffing diverse stainless steel components. This includes elbows, tanks, and fittings, all with the sole aim of achieving a customer-specified surface finish, denoted by a requisite Ra value suitable for stringent sanitary applications. The polishing process is done in accordance to ASME standards and conforms to industry requirements.
passivation
Grinding, brushing, welding, polishing and long-term usage of stainless steel removes the preventive layer of chromium oxide; consequently reducing its inherent corrosion-resistant properties. The passivation process replenishes the passive surface by forming chromium oxide layer, effectively reinstating the stainless steel to its initial chemical composition and bolstering its enduring resistance to corrosion.
borescoping
Post fabrication, each weld undergoes a meticulous and stringent quality control process, complemented by thorough inspections utilizing state-of-the-art borescoping technology. This exhaustive approach is implemented to guarantee that our equipment not only meets but consistently surpasses the most elevated standards that define our unwavering commitment.
