Import Slip On Flanges
The calculated strength from Slip On flanges under internal pressure is two-thirds that of Welding Neck Flanges, and their life under fatigue is about one-third that of Welding Neck Flanges. Import Slip on Flanges are made in India / China / Taiwan. All Slip on Flanges are supplied with MTRs for traceability.
The connection with the pipe is done with two fillet welds, one on the outside and the other on the inside of the flange.
After sliding the flange on the pipe, the distance inside the flange between the end of pipe and the flange face should be: Wall thickness of pipe + 3 mm (1/64 inch). This space is necessary to prevent damage to flange face during the welding process.
