My name is Steven Richards. I work as a Chartered Engineer involved in the design
and commissioning of pressurised plant and equipment. I am also a registered
European Welding Engineer. I have taken over this website from an retired work colleague whom some of you may know and I very much hope to be able to keep this site as informative as he did.
