Introduction
Piping systems are vital to industries across the globe. Strong, leak-proof joints ensure safety, performance, and reliability. One of the most common flange types is the CS Slip-On Flange.
At Fortis Forge, we manufacture CS Slip-On Flanges with precision and strict quality control. This blog explains everything you need to know about slip-on flanges, including their design, benefits, and applications.
What is a CS Slip-On Flange?
A CS Slip-On Flange is made from carbon steel. As the name suggests, the pipe slips into the bore of the flange. It is then welded inside and outside for strength.
This design makes it easy to install and align compared to other flange types. Slip-on flanges are cost-effective and widely used in industries with low to moderate pressure systems.
Importance of Slip-On Flanges
Slip-on flanges are highly popular because they combine affordability and reliability.
Key functions include:
