Original product description
A Stainless Steel Slip-On Flange (SO Flange), also known as a Slip-On Neck Flange, is a widely used pipe connecting component. It is designed to be slipped over the end of a pipe and then welded both inside and outside to provide sufficient strength and prevent leakage.
Its combination of ease of installation and cost-effectiveness makes it a popular choice for a wide range of medium and low-pressure applications. Key Features & Overview The defining feature of the SO flange is its low hub or neck that the pipe slides into.
The primary welding involves two fillet welds: one on the hub's outside and one on the inside, making the connection robust.
Main Characteristics: Ease of Alignment: The bolt holes are full circles, making it significantly easier to align with the bolt holes of a matching flange during assembly compared to other types like lap joint flanges.
Cost-Effective:Generally less expensive to manufacture and purchase than comparable Welding Neck (WN) flanges. Requires Welding:Involves more welding than a socket weld flange but is structurally stronger for its class.
Pressure Limitations: Due to its design and the nature of the connection, it is best suited for low-pressure and non-cyclic services. Its fatigue strength is lower than that of a welding neck flange.
Technical Specifications & Standards SO flanges are manufactured to adhere to international standards to ensure compatibility and safety. Common Standards: ASME/ANSI B16.5: The most common standard for pipe flanges and flanged fittings in North America and internationally for sizes NPS ½" to 24".
ASME/ANSI B16.47: Covers larger diameter flanges (NPS 26" to 60"). EN 1092-1: The European standard common in the UK and EU. MSS SP-44:Standard practice for steel pipeline flanges. AWWA C207: Standard for steel pipe flanges for waterworks services.
Pressure Classes: Common ASME pressure classes are Class 150, Class 300, Class 600, etc. Common PN (Pressure Nominal) ratings per EN standards are PN6, PN10, PN16,PN25, PN40. The dimensions (thickness, bolt hole size, and number of bolts) change with each pressure class.
Facing Types: The most common facing is the Raised Face (RF). Other types include Flat Face (FF), Ring-Type Joint (RTJ), Tongue and Groove (T&G), and Male and Female (M&F). Material & Properties The stainless steel material grants the
