The BH01 is a welded solid-drilled thermowell, machined from solid bar stock and directly welded to the process pipe, suitable for high-pressure and high-temperature service. It is available in four profile types: straight (S), tapered (T/Z) and stepped (L). The thermowell outside diameter, overall length and insertion length can be customised to the application. Materials cover 304/316/316L/321 stainless steel and heat-resistant steels such as 20#, 12Cr1MoV, 15CrMo and 15NiCuMoNb5-6-4, with vortex shedding calculations available to ASME PTC19.3.
