Mechanical strength component design

Components manufactured in accordance with standards listed in Table IP-8.1 shall be considered suitable for use at pressure-temperature ratings in accordance with para. IP-2.2.2 or para IP-2.2.3, as applicable. The rules in para. IP-3.2 are intended for pressure design of components not covered in Table IP-8.1, but may be used for a special or more rigorous design of such components, or to satisfy requirements of para. IP-2.2.3. Designs shall be checked for adequacy of mechanical strength under applicable loadings enumerated in para. IP-2.1. 

Mechanical strength and thermal stability of catalyst particles are always of concern to process designers. In some cases it may be the most critical feature. This was emphasized, for e.xample, in steam reforming. Strong pellets with good thermal resistance are required. Catalyst designers use mixed oxides fired at high temperatures to form ceramic compounds, Particles must be preformed and active components added later.
