ASTM B564 Socket Weld Nickel Alloy Pipe Flanges Alloy 31 UNS N08031 1/2 Inch - 24

1. ALLOY 1.4562 / UNS N08031 / ALLOY 31

Corresponding Standards: EN 1.4562, UNS N08031 MATERIAL DESCRIPTION

• Alloy 31 is a nickel, chromium and molybdenum stainless steel with nitrogen and copper additions. It combines moderate tensile strength and high ductility with excellent corrosion resistance in sulfuric acid, reducing and oxidizing media and has strong resistance to corrosion and erosion corrosion in phosphoric environment.
• Typically the alloy has PREN of ≥ 48, which ensure that the resistance to pitting corrosion is high.

2. SOCKET WELD PIPE FLANGES

Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". Coastal Flange provides Socket Weld pipe flanges in all material grades, specifications and sizes.

3. Advantages and disadvantages of Socket Weld fittings

RF FF RTJ Type Socket Weld Flange , Nickel Alloy Flanges ASTM B564 UNS N08031

The pipe need not be beveled for weld preparation. Temporary tack welding is no needed for alignment, because in principle the fitting ensures proper alignment.
The weld metal can not penetrate into the bore of the pipe.
They can be used in place of threaded fittings, so the risk of leakage is much smaller. Radiography is not practical on the fillet weld; therefore correct fitting and welding is crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods.
Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation
