Slip-on flange · mild steel · ASME B16.5 · UAE stock
The most widely used pipe flange: it slides over the pipe and is fillet welded inside and out. Easy to align on site and lower in cost than a weld neck, it suits most water, air and process lines.

A slip-on flange has a bore slightly larger than the pipe OD, so the pipe slides into it and the flange is attached with two fillet welds, one at the hub and one inside the bore. Because the axial position can be adjusted before welding, alignment is far easier than with a weld neck. Its pressure capacity is roughly two-thirds of a weld neck of the same class, which is ample for most utility and process lines.
Hamza Fasteners stocks MS slip-on raised face flanges from 1/2 inch to 12 inch in ASME B16.5 Class 150 and Class 300, with PN16 drilling for European equipment. They are used on chilled water, fire mains, pump skids, compressed air and general process piping. Pair them with gaskets and stud bolts from the same store and send your list to our Deira, Dubai team for a price.
