Corrective factors for fittings
 

In view of the variety of the different product applications the working pressures stated in our technical tables should only be used as a guide. The stated values are valid for ambient temperatures (20° C). For applications where higher working temperatures are required, please refer to the following information. End fittings may be used at the maximum working pressures stated in the technical tables where the maximum temperatures do not exceed:

Brass up to 50°C 
Malleable cast iron up to 120°C   
Steel up to 120°C   
Stainless steel up to 300°C   

For higher temperatures please use the following information.

For further information, please contact our Engineering Department.

Material: Steel

The maximum permissible working pressures will be reduced where the working temperature exceeds 120 °C.
The correction factor to be applied will be dependant on the end fitting type and material grade.

Material: Stainless steel 

The maximum permissible working pressures will be reduced where working temperatures exceeds 300°C.

Material: Malleable cast iron
