SPI is experienced in retrofitting the vessels to optimize performance or gaining more capacity or foaming etc. SPI is also experienced in providing weldless solutions for the vessels which are already in service. Designed SPI internals will easily pass through manway and can be assembled inside the vessel without any requirement of welding to Vessel wall. SPI offers retrofits for Inlet Devices, Mist Eliminators, Calming Baffles, and Liquid-Liquid Coalescers.
