Export market · GCC · State of Kuwait
In short: Kuwait buys like a refinery: Cr-Mo and H-grade stainless for hot hydrogen units, duplex and nickel alloys for sour water, and carbon steel for everything else, mostly through registered contractors working to KNPC and KOC specifications. Bright Tubes supplies all of it from India to Shuwaikh or Shuaiba with 3.1/3.2 certificates.
Unit by unit
Typical candidates. Licensor and owner specifications make the final choice.
| Unit | Damage mechanism to design for | Typical materials |
|---|---|---|
| Crude and vacuum distillation | Hot crude, naphthenic acid in some cuts | P5, P9, SS 316L, SS 317L |
| Hydrotreaters and hydrocrackers | Hot hydrogen, high pressure, polythionic acid at shutdown | P22, SS 321H, SS 347H, SS 347 |
| Residue upgrading | High temperature, coking, heavy crude | P91, P9, SS 310S |
| Sulphur recovery and sour water | Wet H₂S, ammonium bisulphide | 2205, Alloy 825, A106 Gr B |
| Cooling water and utilities | Brackish or seawater cooling, steam | 2507, CuNi 90/10, P11 |
Buying route
KNPC, KOC or KIPIC issue material specifications and keep approved-vendor lists with time-limited registration.[4]
Foreign suppliers usually sell through a local agent or an EPC already on the list.
Material to the specification, mill certificates, PMI and inspection records ready for the contractor's submittal.
Sulphide scale on austenitic stainless in hydroprocessing units can form polythionic acids when exposed to air and moisture at shutdown, cracking sensitised material.
Common defences: stabilised grades such as SS 321 and SS 347 (with stabilising heat treatment where specified), and shutdown protection such as nitrogen purging or alkaline washing per NACE SP0170.
Turnarounds
Polythionic acid stress corrosion cracking is a classic refinery shutdown problem, and it shapes which stainless grades Kuwaiti hydroprocessing units specify. If your specification calls for stabilised or low-carbon grades, we match the exact grade and heat-treatment condition. More in sensitisation and L grades and stress corrosion cracking.

Kuwait buyer questions
Direct supply to KNPC or KOC needs registration as an approved vendor, which is time-limited, must be renewed, and for foreign firms requires a local agent.[4] Most imported pipe reaches Kuwait through a registered contractor or local agent; we supply to their purchase specification and documentation requirements.
Hot hydrogen service runs in Cr-Mo such as P22 and stabilised H-grade stainless such as SS 321H and SS 347H, chosen per API RP 941 and the licensor's specification. See H grades for high temperature.
Reported design figures: Al-Zour 615,000 b/d, and Mina Abdullah and Mina Al-Ahmadi upgraded under the Clean Fuels Project to roughly 800,000 b/d combined.[1][2] Together that is about 1.4 million b/d, all of which needs maintenance and turnaround material.
Shuwaikh Port near Kuwait City for containers, and Shuaiba Port south of the city next to the refinery and petrochemical belt.
Yes, if the list reaches us early enough to produce mill items. Stock items ship after inspection; we confirm each mill item's lead time on the quotation and track it to your turnaround date.

Trade rules and project schedules change. Confirm current requirements with your customs broker or project authority before shipment.
Send the material list with the shutdown date. We confirm what ships from stock and what needs mill time.
