The Long Weld Neck (LWN) connection is the lightest and most economical of FCI standard connections offered for use where a minimum of reinforcing area is required. It is the most commonly used nozzle in the ASME pressure vessel industry. LWN is also the lightest wall connection of the FCI nozzle family.

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe.. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).Nozzles
