Pressure Rates

The maximum working pressure is indicated for each item in the catalogue - before specifying or using a part , please take notice of the pressure indications.

All pressure indications are based on a working temperature of -20°Celsius to +90°Celsius. Temperatures outside of this range will reduce the maximum working pressure.

The indicated working pressure refers to the flange only.

Material

Forged components are manufactured from ST52,3 ( FE510 ) material - all items in the catalogue have the material used nominated.

Surface Protection

Standard finish for all flanges is blank steel with protection fluid against rust.

Flanges which do not require welding can be supplied in a zinc passivated finish.
