PROJECTEnquire ↗Process plant upgrades
Replacement of an original steel tank in Přerov with a new vessel and agitator included manufacturing design, workshop preparation and installation. The tank, with an internal diameter of 1,950 mm, was split into two sections and welded together on site. The design addressed a stainless-steel shell and bottom, a top cover with agitator support, and five process nozzles connecting to the existing equipment.
Delivery scope & origin

The project in context
Replacement of the existing equipment required a split vessel design and interfaces to the original process pipework.
Workshop fabrication and trial assembly were followed by transport of the two sections, site welding, fitting of accessories and pipework connections.
The tank was designed as upper and lower assemblies, which were welded together at the installation site after transport. Manufacturing preparation covered the vessel geometry, top cover, agitator support and interfaces between the components. Workshop trial assembly took place before dispatch.
The drawings specify grade 1.4571 stainless steel, also designated AISI 316Ti, for the shell, bottom and main connection parts. The top cover and agitator support are separate steel components within the assembly. Splitting the tank allowed fabrication and completion work to be adapted to the installation conditions.
The connection layout serves pump suction, drainage, overflow and the incoming process stream. The fifth nozzle provides a spare connection. Engineering therefore addressed nozzle positions and orientation alongside placement of the new vessel in the existing process location.
The installation scope included dismantling the original tank and removing its lining, transporting the new assembly, completing welds, fitting accessories and connecting the pipework. The work combined stainless-steel fabrication with interfaces to the existing process equipment.
A weld map was prepared for the tank with 21 identified weld positions. It specifies full visual inspection and 20% liquid penetrant inspection for the individual positions, linking inspection requirements to specific locations on the assembly.
The inspection plan covered workshop welding and completion of the tank during installation. The invoiced scope included one tank with an agitator and its installation interfaces.
