What are slip-on flanges, and When do we use slip-on flange? Professionalمنذ سنة - Multimedia - Saïda - 186 الآراء
There are various types of Slip-on flanges, including the Slip-On Reducing Flange, raised face slip-on flange, and RTJ slip-on flange. The flange is applicable for reducing the line size and limitation of the space limitations. These flanges work along with the weld neck flange and reducer combination. They are useful when the flow is directed from the smaller size to the larger size. Slip-On flanges are welded internally and externally. The welding offers them the ability to prevent leakage and sufficient strength.
Uses of Slip-on flanges
Slip-on flanges are primarily applicable for fluids working at low pressure. Also, these flanges work well with little chance of leakage. These flanges work well in cooling water lines, firefighting water lines, and low-pressure compressed airlines. Along with this, slip-on flanges are suitable in process lines to maintain the stream of steam, oil, gas, condensates, etc. These flanges are applicable for low pressure and higher temperature system.
Common Uses and Features of Blind Pipe Flanges
Blinds are flanges without a center bore (hole or opening) and are available in both Raised Face (RF) and Flat Face (FF) styles. While most flange types create a connection point that allows the flow of liquid, gas, or air, blind flanges are used to seal the end of a piping system and prevent flow. Blind flanges may be used when testing pipe pressure, to create an access point in a piping system, to temporarily seal a piping system while modifying or repairing the line, or to create a long-term seal to terminate a piping system.
A blind flange is bolted, rather than welded in place. This allows easier access as needed for pipe system upkeep, inspection, or to allow for future expansion. Pairing with a gasket creates a tight seal: The gasket fills the space between the flange faces, which prevents liquid or gas leaks.
How to Choose the Right Blind Flange
Blind pipe flanges may be produced to match bolt hole measurements for slip-on or weld neck flanges, or if needed, can be custom machined to any other specifications. Either way, when purchasing flanges, choose the appropriate flange features, material, dimensions, and class to meet your application needs.
Find the Best Blind Flange Material for the Job
When choosing blind flanges, you must consider the best flange material and dimensions in relation to the piping standards and requirements of your intended application. Generally, your flange material should match the connecting pipe material. The most common blind flange materials are steel and stainless steel.
