Overview
Product overview
Raised Face Flanges are integral components in piping and plumbing systems, ensuring a robust and leak-proof connection.
What is a Raised Face Flange?
A Raised Face Flange features a raised portion around the bolt holes on its face, designed to compress a gasket between two flanges effectively. This raised area provides additional support to the gasket, preventing leaks even under high pressure and temperature conditions. Raised Face Flanges are essential in applications demanding critical sealing and reliability, such as oil and gas, petrochemical, and other industrial sectors.
Types of Raised Face Flanges
At Fortune Fittings Private Limited, we offer a variety of raised face flanges, each tailored for specific applications:
- Weld Neck Flanges: Ideal for high-pressure applications, these flanges have a long tapered hub that provides additional strength.
- Slip-On Flanges: These are easy to install and are suitable for low-pressure applications.
- Blind Flanges: Used to close the end of a piping system, preventing flow.
- Threaded Flanges: Ideal for small-diameter pipes in low-pressure applications, these flanges are threaded to allow for easy connection.
Ready Inventory and Custom Solutions
We maintain a ready inventory of raised face flanges in various sizes, including 2-inch, 3-inch, 4-inch, 6-inch, and 8-inch options. Additionally, we offer custom solutions tailored to meet specific requirements, ensuring our clients receive the best products and services.
