Nozzle

A tank or vessel nozzle, abbreviated as NOZ, refers to an opening or connection point on a tank or vessel that allows for the ingress or egress of fluids, gases, or other substances.  Nozzles are typically located on the sidewall or the top/bottom of the tank and are used for various purposes, including filling, draining, sampling, venting, or connecting auxiliary equipment.

Nozzles are designed to accommodate specific requirements based on the intended use of the tank or vessel.  They are often custom sized and configured to match the process needs and to ensure compatibility with the connected piping or equipment.  The size, shape, and type of nozzle can vary depending on factors such as the volume of fluid to be handled, the pressure and temperature conditions, the desired flow rate, and the nature of the substance being transferred.

Nozzles on tanks or vessels may include features such as flanges, threaded connections, bolted or welded connections, specialized fittings for different types of connections, and reinforcing pads used to strengthen the nozzles.  They are often designed to allow for sealing mechanisms, such as gaskets or O-rings, to ensure leak-tight connections.

These tank or vessel nozzles serve as access points for various operations, including filling the tank, emptying or draining its contents, adding or withdrawing substances, connecting pipes or hoses, attaching instrumentation or measurement devices, and facilitating maintenance or inspection activities.  The proper design and selection of tank or vessel nozzles are crucial to ensure safe and efficient operation of the system, including fluid containment, controlled flow, and the avoidance of leaks or structural issues.  It is important to consider factors such as pressure ratings, material compatibility, corrosion resistance, and any applicable regulatory or industry standards when choosing and installing tank or vessel nozzles.
