Slip On Flanges

About

Slip on flanges are commonly used where a simple, practical flange connection is needed. They are designed to fit over the pipe before welding, which makes alignment during fabrication more straightforward and helps keep installation efficient on many standard piping jobs. That is why they are often used on general service lines, utility piping, water systems, and fabricated assemblies. PipingNow offers this style across the pressure classes commonly used in industrial service. The collection includes 150#, 300#, and 600# options, with raised face configurations available across the product mix. Why This Style Is Commonly Used The main advantage here is fit-up. Because the flange slips over the pipe, positioning during assembly is generally more forgiving than with some other connection styles. For many fabricators and installers, that makes it a practical choice on systems where the connection method is straightforward and repeatable. general service process piping utility and water lines fabrication and skid packages pump and equipment connections shop assemblies standard industrial piping systems Classes and Configurations This collection covers 150#, 300#, and 600# pressure classes. In most cases, selection starts with the class, nominal size, facing, and the requirements of the mating connection. Raised face options are available across multiple sizes, helping maintain consistency with the rest of the system. Where They Fit Best This style is a strong fit for systems where ease of assembly matters and the specification does not call for a different flange design. It is widely used on plant piping, mechanical systems, utility service, and other installations where a familiar welded flange connection is appropriate. What to Check Before Ordering Before ordering, confirm the pressure class, nominal size, facing, material, and mating flange requirements. The key is making sure the part matches the piping system already being built. If one of those details is off, t
