Most Popular Flange Styles

A Flange is a key component in piping systems and pressure vessels, providing a secure way to connect pipes, valves, or equipment. A Flange, by definition, secures, strengthens, or attaches. For us, Flanges create strong, leak-proof joints.

Frequently Asked Questions

Frequently asked questions illustration — weld neck flange
A flange is essential for connecting pipes, valves, pumps, and other equipment in piping systems. It ensures a secure, leak-proof joint and facilitates assembly, disassembly, and maintenance of the system.
A flanged fitting is a connection with an extended rim (flange) designed for bolting two components together. This ensures a robust, sealed, and easy-to-maintain connection in high-pressure and high-temperature environments.
The most commonly used flange types are:

Weld Neck Flanges – Ideal for high-pressure applications with a tapered hub for structural integrity.
Slip-On Flanges – Easy to install and cost-effective for low-pressure systems.
Blind Flanges – Used to seal the end of pipelines or pressure vessels.
The weld neck flange, including its variation, the long weld neck, is the most widely used due to its strength, durability, and suitability for high-pressure and high-temperature applications.
