Compression, Bladder and Diaphragm. Each tank style has models that are either ASME or Non-ASME coded. Tanks range in size from 2 to 10,000 gallons. Most of Wessels pressure vessels are designed using a pre-pressurized vessel with an internal bladder or diaphragm to manage fluids under pressure. The majority of Wessels products are standard catalogue models, with over 6,000 tanks in inventory for immediate shipment. Custom tanks are produced to customer specifications, for high pressures and/or special materials for severe duty applications.
