Frequently asked questions

What is the difference between 304 and 316 stainless steel pipe?

316 / 316L contains 2% molybdenum, which resists chlorides (sea water, pool water, brine, many acids) far better; 304 is adequate for potable water, food and indoor use at 30–40% less. Use 316L on the coast, in chemical plant and for pharma.

What is the price of SS 316 pipe in the UAE?

Landed Jebel Ali in pallet quantity, Turkish 316L tube and pipe typically comes in 8–15% under Dubai stockist prices; freight adds 60–90 USD/t and duty 5%. Ask for CIF per metre.

What is Schedule 10S?

The light-wall stainless schedule (ASME B36.19M) — e.g. 2" = 60.3 × 2.77 mm — standard for water and process lines; 40S is the heavier wall for steam and pressure.

Welded or seamless stainless pipe?

Welded (A312 W / EN 10217-7) for water, food, HVAC and most chemical lines — cheaper, uniform wall; seamless (A312 S / EN 10216-5) for high pressure, high temperature and where the spec requires it.

Is stainless steel good for pipes?

Yes — 50+ years without scaling or corrosion in water, no lining, hygienic for food and pharma, and full recyclability; the cost is 4–5× carbon steel per ton but lower over the life of the system.

Do you supply fittings and flanges?

Yes — butt-weld fittings A403 / EN 10253-4, flanges A182 / EN 1092-1, threaded fittings, sanitary clamps and bends, in matching grade and schedule.

Can you bend and weld stainless pipe?

Yes — CNC bending, orbital TIG welding, pickling and passivation, re-polishing; handrail and process skids assembled to drawing.
