Slip-on raised Face Flange is commonly used in piping systems, where the bolt-hole flange bolt hole pattern slips over the pipe’s end and welds in place. These flanges are available in various sizes and designs to meet the specific demands of the application. In this blog, we will break down everything you need to know about Slip-On Raised Face Flange so you can make the right purchasing decision for your industrial needs.
A Slip Raised Face Flange is a pipe flange used in piping systems. It is typically round and has a raised edge or lip on the inside, which helps to form a strong joint between adjacent pipes. The advantage of this flange type is that it does not require welding, making installation easy and fast. Its high face pressure rating makes it ideal for use in high-pressure applications such as pumps, filters, coolant lines and other industrial equipment.
Types of Slip-On Raised Face Flange
There are two main slip-on raised face flange types: standard and long. Standard flanges are used for light to medium-weight applications, while long flanges are designed for piping systems that require greater strength and support. Slip-on raised face flanges come in various dimensions and materials, such as stainless or carbon steel.
Flange Pressure Classes
Slip-on Raised Face Flanges are available in different pressure classes, which denotes the flange’s ability to handle pressure without structural damage. The American Society of Mechanical Engineers determines the ratings, including ANSI/ASME 150, 300, 600, 900, 1500 and 2500. Choosing a flange with the correct pressure rating for your system is essential to avoid potential accidents or breakdowns.
Installation of Slip-On Raised Face Flanges
Installation of slip-on raised face flanges is straightforward, but it requires careful handling and preparation. First, ensure the pipe and the flange are clean and smooth before welding. Next, align the bolt holes of the flange with the pipe, then insert bolts and proceed to tighten the nuts with a torque wrench. Tightening the nuts in a crisscross pattern is recommended to prevent warping. During installation, remember that the flange’s raised face must align perfectly against the flat surface of the mating flange to prevent leaking.
Maintenance
Like all piping system components, slip-on raised face flanges need care and maintenance to ensure longevity and performance. Inspections should be periodically performed to check for corrosion, leaks, and damage. Regular cleaning of the flange and gasket is also essential to prevent potential flow disruptions and reduce repair costs. In the event of damage, flanges should be repaired or replaced immediately to prevent further complications.
Conclusion
Slip-on Raised Face Flanges are versatile and commonly used in piping systems because of their convenient installation, simple design, and availability in different materials and dimensions. Understanding the different types, pressure ratings, installation process, and maintenance requirements can help you decide when choosing a slip-on raised face flange for your industrial needs. By following proper installation and maintenance procedures, you can ensure optimal performance from your flange and minimize downtime and repair costs.
