Q-Lip Nozzles

A Q-lip nozzle is a unique connection design that contains a Q-lip (insert lip) that is welded directly into the pressure vessel wall during the fabrication assembly. This allows for simpler and economic installation, as well as easier and less costly weld inspections. The design also provides superior toughness and ductility in high stress areas. It is essential when the pressure vessel design requires capability of withstanding cyclic loading conditions during its service in the field. The most common application for this type of a connection is when an existing nozzle on the pressure vessel requires replacement.
