Notes

For applications outside the typical use range, SPITMAAN® recommends engineering design calculation to specific application and extra care to be taken during installation. Uniform torquing during installation using ASME recommended methodology is mandatory. Retorquing after a thermal cycle should be done after cooling down of equipment is recommended. Please contact SPITMAAN® if further guidance is required.
Except molten alkali metals and elemental fluorine.
