The integrity of piping systems is dependent on various considerations and principles that should be observed when designing, constructing and maintaining process plant piping. Pipework is made up of many components including pipes, flanges, supports, gaskets, bolts, valves, strainers, flexibles and expansion joints. Such components are available in a variety of materials, types and sizes and may be What You Need to Know About T&P Valves on Hot Water May 22, 2015 · Combination temperature and pressure relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6 (152mm) of the water storage tank. Valves must be located so as to assure isolation from flue gas heat or other ambient conditions that are not indicative of stored water temperature. MAXIMUM PIPING OPERATING PRESSURE AS relationship between pressure head and pressure is given in equation [4]. SG ppsi H ftfluid 2.31 ( ) ( ) [4] where (H) is the pressure head, (p) the pressure and (SG) the specific gravity of the fluid. If the shut-off pressure exceeds the allowable operating pressure as calculated by the ASME code, then pressure relief devices may have to be NBIC Pressure Relief Device Inspection Guide 1-19-10Pressure relief devices are used to provide a means of venting excess pressure which could rupture a boiler or pressure vessel. A pressure relief device is the last line of defense for safety. If all other safety devices or operating controls fail, the pressure relief device must be capable of venting excess pressure. 2.
