Overview

Aluminium Slip-On Flanges for Marine and Air Lines in the UAE

An aluminium slip-on flange is the light alloy equivalent of the steel SORF. The aluminium pipe slides into the bore and is TIG or MIG welded with a matching filler. Aluminium forms a natural oxide layer that resists atmospheric and sea air corrosion, and the parts are roughly one-third the weight of steel. Strength falls quickly with temperature and after welding, so aluminium flanges are used at moderate pressure and ambient temperature.

Hamza Fasteners supplies aluminium slip-on flanges from 1/2 inch to 12 inch, drilled to ASME B16.5 Class 150 or PN16, in weldable alloys such as 6061. Typical uses are boat and yacht piping, compressed air ring mains, ventilation and food plant utilities. Send the size, drilling and alloy requirement to our Dubai team and we will confirm stock and price.

FAQ

Common questions

Can I connect an aluminium flange to a steel flange?
Yes, the drilling is the same, but isolate the two metals to avoid galvanic corrosion, especially in wet or marine conditions. Use an insulating gasket and sleeves and washers on the bolts.
Which aluminium alloy are your flanges made from?
Slip-on flanges are generally supplied in weldable alloys such as 6061, which offer good strength and corrosion resistance. If your project specifies a marine alloy such as 5083, tell us and we will confirm availability.
What sizes of aluminium slip-on flange do you stock?
We offer 1/2 inch to 12 inch with ASME Class 150 or PN16 drilling. Other drillings and larger diameters can be supplied to order. Give the pipe OD and wall thickness so the bore suits your aluminium pipe.
How much do aluminium flanges cost in Dubai?
Aluminium flange prices depend on size, alloy, drilling and quantity. Send your requirement on WhatsApp and Hamza Fasteners will reply with a quotation. Mention the alloy if your design specifies one, plus the drilling standard and facing.
Do you deliver aluminium flanges outside Dubai?
Yes. We deliver across the UAE and ship to the GCC and Africa, including to shipyards and boat builders. Aluminium flanges are light, so courier dispatch to other emirates is practical for small orders.
