August 12, 2014 - Watlow received a Certificate of Conformance from the American Society of Mechanical Engineers (ASME) designating that its flange heaters meet the Boiler and Pressure Vessel Code (BPVC), Section IV revised requirements, and can apply the ‘H’ stamp to its flange heater assemblies. Recently, the ASME revised its BPVC, Section IV, “Rules for the Construction of Heating Boilers,” requirements for boilers, including commercial boilers, industrial boilers, heating boilers and low pressure boilers. Boilers in which steam or other vapor is generated at pressures not exceeding 15 psig, and high temperature water boilers intended for operation at pressures not exceeding 160 psig and/or temperatures exceeding 250°F now require heaters from suppliers that are certified.
Watlow’s ASME certified flange heaters have long immersed length capability to help reduce costs by keeping the pipe and flange sizes to the smallest possible design size. This product is available with a variety of heating elements and flange materials (including square flanges) to meet specific requirements, and eyebolt holes or lift lugs are drilled and tapped to facilitate lifting for large units into the vessel. Typical applications include boilers, high temperature water boilers and steam generators.
