Slip-on flanges are a popular type of pipe flange designed to slide over the end of a pipe and then welded both inside and outside to provide strength and prevent leakage. Offering easy installation, cost-effectiveness, and versatility, slip-on flanges are widely used in low to moderate pressure piping systems across industries such as oil & gas, petrochemical, chemical processing, water treatment, shipbuilding, and general construction.
Manufactured with a slightly larger bore than the pipe’s outer diameter, slip-on flanges allow for quick alignment and easy fabrication, reducing labor and installation costs. They are particularly suitable for non-critical applications where welding integrity and fatigue resistance are less stringent compared to weld neck flanges. Available in raised face (RF), flat face (FF), and ring type joint (RTJ) designs, slip-on flanges accommodate various sealing surfaces and connection requirements.
At Middle East Piping, we supply a complete range of slip-on flanges in materials including carbon steel (ASTM A105), stainless steel (ASTM A182 F304/F316), duplex stainless steel, and alloy steels. Our slip-on flanges comply with international standards such as ASME B16.5, ASME B16.47, and EN 1092-1, and are available in pressure classes ranging from Class 150 to 2500 or PN6 to PN100. Sizes range from ½” to 48”, and all flanges are delivered with EN 10204 3.1 / 3.2 certification, ensuring material traceability and project compliance. click here
