Chapter 5:Water Heaters, Plumbing Code of the Texas

The discharge piping serving a pressure relief valve, temperature relief valve or combination thereof shall:Not be directly connected to the drainage system. Discharge through an air gap located in the same room as the water heater. Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap. Codes & Standards - ASMESetting the Standard for Over 125 Years. ASME offers a continuously evolving portfolio of standards across a wide range of topics, including pressure technology, power plants, elevators, construction equipment, piping, nuclear components, and many more.

    1. See full list on up.codesAPI - Valve StandardsFlanged Steel Pressure Relief Valves. The standard is a purchase specification for flanged steel pressure relief valves. Basic requirements are given for direct spring-loaded pressure relief valves and pilot-operated pressure relief valves as follows:orifice designation and area; valve size and pressure rating, inlet and outlet; materials; pressure-temperature limits; and center-to-face dimensions, inlet Pressure Relief Devices - nationalboardPressure 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.

      (a) CWP (Cold Working Pressure) is the maximum pressure rating allowed under normal "ambient" temperature conditions, which are usually understood to be -20°F to 100°F (-29°C to 38°C), Certain "ambient temperature" standards and practices have a different range or are limited by recognized codes and standards. T&P and ASME Safety Relief Valves - Wattspressure increase. When a relief valve is dripping, it is typically due to thermal expansion. When water is heated, it expands. This causes excess pressure in the system. When the T&P relief valve senses this excess pressure, it opens relieving the thermal expansion* and returning the pres sure back to normal conditions.
