Pressure Tanks – Petrochemical Sector (USA) 2016

Sector: Petrochemical
Country: United States
Year: 2016
Category: Pressure Vessels – ASME U-Stamp

Scope:
Design, supply, and on-site erection of n. 2 stainless steel pressure tanks for a PET plastic production facility in the USA. The tanks were engineered to handle catalytic and degassing processes, in compliance with ASME VIII Div.1, with U-Stamp certification and registration with the National Board.

Objective:
To support a large-scale plastic production line, CITAL delivered a Catalyst Mix Tank and a Deg Feed Tank made from ASTM A240-304 stainless steel, with full documentation and third-party inspection. Both vessels were designed for reliable performance under process pressure and temperature fluctuations, while meeting stringent U.S. code requirements.
