Seamless & welded stainless steel pipe in TP304, 304L, 316, 316L, 321 and 310S, plus duplex 2205 & super duplex 2507 — schedules SCH 5S to XXS. Available across Qatar, the UAE and Saudi Arabia for chemical, desalination, marine, food and pharma service, with EN 10204 3.1 / 3.2 certificates.
Stainless steel pipe is specified wherever corrosion, hygiene or high temperature rule out carbon steel — chemical and petrochemical plants, seawater and desalination, food & dairy, pharmaceutical process, and marine systems. AAM Steel supplies the full range of austenitic grades (TP304/304L, 316/316L, 317L, 321, 347, 310S and super-austenitic 904L) and duplex / super duplex (2205, 2507) to ASTM A312 (seamless & welded), A358 (EFW large-diameter), A778 (welded unannealed), A249 / A213 (welded & seamless tube) and EN 10216-5 / 10217-7. Sizes ship in both NPS (inch) and DN (metric) — from DN6 to DN600 — and hygienic dairy tube (DIN 11850 / ASME BPE) is covered on our sanitary & hygienic tube page.
The most common choice is 316L — its molybdenum content gives strong resistance to chlorides and pitting, making it the default for marine and desalination work in the Gulf. For the most aggressive warm-seawater service, super duplex 2507 and 6-Mo grades take over. Every pipe ships seamless or welded, in the schedule you specify, with full material traceability.
General-purpose & food-grade austenitic. Excellent all-round corrosion resistance.
Mo-bearing — chlorides, marine, desalination, chemical. The GCC workhorse.
Stabilised & high-temperature grades for creep and heat service.
High strength + chloride resistance for seawater & offshore (ASTM A790).
Higher-Mo 317L for scrubber & chemical service; 347/347H stabilised for high-temperature.
Super-austenitic (904L, 254 SMO, AL-6XN) for sulphuric acid & warm seawater.
Every size in both inch (NPS) and metric (DN6–DN600), SCH 5S to XXS.
