Stainless Steel Slip On Flanges Manufacturer and Supplier In India

A stainless steel slip-on flange is a type of flange that is slipped over the end of a pipe and then welded in place. It is the easiest type of flange to install, and is often used in low-pressure and low-temperature applications. Slip-on flanges are also used in usages where frequent dismantling is required, as they can be easily removed and replaced. Stainless steel slip-on flanges are normally made from austenitic stainless steel grades such as 304 and 316, which are known for their exceptional corrosion resistance. They come in various sizes and pressure ratings, and can be used with a variety of pipe schedules. Benefits of stainless steel slip-on flanges are easy to install, cost-effective than other types of flanges, can be used in low-pressure and low-temperature applications and can be easily removed and replaced. Applications of stainless steel slip-on flanges water and wastewater treatment, chemical processing, food and beverage processing, pharmaceutical manufacturing, HVAC systems, plumbing systems and fire protection systems.
