Monobloc-forged vessels, forged from a single ingot, are available from Engineered Pressure Systems, Inc. (EPSI). These vessels feature a simple design that can be inspected on all surfaces (inside, outside and ends) to establish that no cracks are developing. Many other vessels have not only exceeded their "service life" but also their "theoretical life" and are still in service -- some after more than one million cycles of operation. The ability to inspect all areas of a vessel, during and after its predicted life, helps assure that the vessel is operating safely.
