FAQ

What are suitable materials for thermowells and protection tubes for negative temperatures?

The first choice for high-temperature applications should always be stainless steel, such as 1.4404  (Approval per AD2000 W10 down to -270 °C) or 316L. Carbon steels should be considered carefully in detail, through the effect of the drop-off effect.

Can the calculations per ASME PTC 19.3 TW-2016 be used for thermowells and protection tubes?

No. The calculation per ASME PTC 19.3 TW-2016 is only used for thermowells in tapered, straight or stepped designs from solid materials, such as Model TW10, TW15, TW20, etc.
