Pressure Vessels

SEICO designs pressure vessels which are closed containers usually made of steel or stainless steel, and can be built according to your requirements. They are manufactured as welded assemblies, and go through rigorous testing to ensure that they can hold liquids or gases at a pressure higher than ambient pressure. Our pressure vessels can be constructed for use in different processes, and follow the design standards of worldwide requirements.
