Self Reinforced Nozzles
A Self Reinforced Nozzle is a type of heavy-duty forged fitting used to create a branch connection on a pressure vessel or high-pressure piping system. Its key feature is the integral reinforcement built into the nozzle's body, which has a thicker, contoured wall. This design provides all the necessary strength to compensate for the opening cut into the main vessel, eliminating the need for a separate reinforcing pad. This simplifies the welding and inspection process, reduces stress concentration points, and creates a stronger, more reliable connection for demanding applications.

Weldolets / Nippolets / Elbolets / Latrolets
This family of fittings, commonly known as "O'lets" or Branch Outlet
Fittings, provides a strong, reliable method for creating branch connections from a larger
pipe. They offer a smoother flow transition and a stronger weld than a traditional stub-in connection.
• Weldolet®: Creates a 90° butt-welded branch connection.
• Nippolet®: A weldolet base with an extended nipple body, used for valve or
instrument take-offs.
• Elbolet®: Welded onto an elbow to create a branch outlet.
• Latrolet®: Creates a 45° lateral branch connection.

Tube Sheets
A Tube Sheet (or tubesheet) is a critical component in shell & tube heat exchangers, condensers, and boilers. It is a precisely machined plate, typically circular, designed to hold and support the ends of the tubes. Its primary functions are to seal the tubes, preventing the shell-side fluid from mixing with the tube-side fluid, and to provide structural stability to the entire tube bundle. The material selection and high-precision drilling of the tube sheet are vital for ensuring the longevity and leak-proof performance of the heat exchanger.
