The calculated strength from a Slip On flange under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter.
The connection with the pipe is done with 2 fillet welds, as well at the outside as also at the inside of the flange.
The X measure on the image, are approximately:
Wall thickness of pipe + 3 mm.
This space is necessary, to do not damage the flange face, during the welding process.
A disadvantage of the flange is, that principle always firstly a pipe must be welded and then just a fitting. A combination of flange and elbow or flange and tee is not possible, because named fittings have not a straight end, that complete slid in the Slip On flange.
APPLICATIONS Of ASME B16.9 ASTM A182 F53 SORF Flange:
1. petrochemical industry
2. Pharmaceutical industry
3. Food industry
4. Aviation and aerospace industry
5. Architectural decoration industry
6. Oil and gas industry
Other Features:
1) Chemical and Physical characteristic: durable, corrosion resistant and high-temperature resistant
2) We also produce flange with special specifications according to customers’ requirements;
ASME B16.9 ASTM A182 F53 SORF Flange is commonly lower in price than f53 weld neck flange, and to this effect are a popular choice for our customers. However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher life expectancy than slip-on flanges under duress.
The f53 sorf flange is positioned so the inserted end of the pipe or fitting is set short of the flange face by the thickness of the pipe wall plus 1/8 of an inch, which thus allows for a fillet weld inside the SO flange equal without doing any damage to the flange face. The back or outside of the f53 sorf flange is also welded with a fillet weld.
