Introduction
Carbon steel flanges are critical components in industrial piping systems. They connect pipes, valves, and equipment with secure, leak-proof joints. Global industries demand high-quality flanges that meet international standards.
Carbon steel flange manufacturers play a vital role in supplying reliable products. They ensure safety, performance, and durability in pipelines used in energy, construction, and chemical sectors.
Fortis Forge, a leading name in forging, has built trust by supplying premium carbon steel flanges worldwide. Their expertise reflects decades of manufacturing excellence.
Why Manufacturers Focus on Carbon Steel Flanges
Manufacturers choose carbon steel for flanges because it balances cost and performance. Carbon steel withstands pressure, heat, and mechanical stress effectively.
Compared with stainless steel, carbon steel offers greater affordability. This makes it ideal for projects requiring large volumes of flanges.

Types of Carbon Steel Flanges Produced by Manufacturers
Different industries require different flange designs. Leading manufacturers like Fortis Forge offer a wide range of flange types.
1. Weld Neck Flanges
Manufacturers design weld neck flanges for high-pressure and high-temperature environments. Their tapered hub reduces stress concentration.
2. Slip-On Flanges
Slip-on flanges slide over the pipe end and are welded inside and outside. They are easy to install and align.
3. Blind Flanges
Blind flanges block pipe ends. They allow future extensions and periodic inspection of pipelines.
4. Socket Weld Flanges
Socket weld flanges provide strong connections for small-diameter pipelines. Manufacturers use them in chemical plants and refineries.
5. Threaded Flanges
Threaded flanges allow assembly without welding. They are safe for explosive environments where sparks are hazardous.
6. Lap Joint Flanges
Manufacturers supply lap joint flanges for low-pressure systems. They offer easy alignment and reduced costs in large projects.
