Have you ever wondered how relaible your relief devices actually are? Ever wondered why five years is the mximum baseline timeframe for testing and replacement? As a result of years of testing, The National Board has accumulated a good deal of data that helps us analyze the quality and reliability of relief valves. We can use the data to determine what industry can expect when they receive a certified pressure relief device, pressure relief valve, or rupture disk device.
