Shreeyan Connect is a reputed manufacturer and supplier of high-quality threaded, lap joint, and socket weld flanges that cater to a wide range of industrial applications. With precision engineering and strict compliance to international standards such as ANSI, ASME, and DIN, our flanges are built to deliver superior performance, strength, and reliability even under the most challenging operating conditions.
THREADED
Suitable for piping systems with small diameters or in hazardous regions where welding is not practical, these flanges are simple to install without welding and are ideal for low-pressure systems.
LAP JOINT
These flanges are ideal for sectors like chemical processing and food production since they are made for applications that need frequent disassembly. They are paired with stub ends and have a high degree of alignment flexibility.
SOCKET WELD
These flanges are frequently found in high-pressure pipes and are built to offer a robust, leak-proof connection, guaranteeing longevity and effective fluid or gas movement.
