SW flange is a forged pipe fitting with a recessed socket that accepts the pipe end for a secure fillet weld connection, providing exceptional strength and leak-proof performance in high-pressure, small-bore piping systems. This article explores features, complete dimensional specifications under ASME B16.5, types, usage methods, primary applications, and a direct comparison with Weld Neck (WN) flanges.
Slip On Flange, also called SO Flange, is a type that slides over the pipe before being welded into place. The pipe inserts completely into the inner bore of the flange, which has a diameter slightly larger than the outside diameter of the pipe to allow for easy insertion.
A lap joint flange is a two-component piping fitting that consists of a loose flange ring and a stub end welded to the pipe.
Best Blind Flange Expert Guide in 2026 This article summarizes the definition, dimensions, types, functions, weight calculation, and applications of blind flanges. What Is a Blind Flange? A blind flange is a solid disk used to seal the end of a piping system, valve, or pressure vessel opening, effec

ASME B16.47 is a standard for large steel pipe flanges developed by the American Society of Mechanical Engineers. Its full name is *Large Diameter Steel Flanges: NPS 26 through NPS 60, Metric/Inch Standard*. It specifically addresses large flanges with pipe diameters of NPS 26 to NPS 60 (DN 650 to DN 1500), specifying pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing requirements.

Schedule 80 or 80S for stainless steel pipes feature thicker walls than Schedule 40 or lower schedules, making them suitable for high-pressure, high-temperature, and corrosive service. Dimensions follow ASME B36.10M and ASME B36.19M. Wall thicknesses are identical except for NPS 10 and NPS 12 in Sch
