Gas turbine spare parts — combustion liners, NGVs and compressor blades for GE, Siemens and Solar turbines in Saudi Arabia — Gulf Union Ozone Jeddah

Gas Turbine Parts Categories

Product Types in Stock

Gulf Union Ozone supplies six gas turbine spare parts families covering hot-section combustion parts, rotating and stationary airfoils, sealing systems, and instrumentation consumables — all manufactured to OEM engineering drawings and alloy specifications for Saudi Arabia turbine fleets.

Type 01

Combustion Liners

OEM-equivalent combustion chamber liners and flow sleeves in Hastelloy X and IN617 nickel superalloy for GE Frame 5, Frame 6B, Frame 7EA and Solar Centaur/Taurus turbines used at Saudi power and gas plants. Each liner is manufactured to OEM geometry with correctly dimensioned dilution holes, film-cooling holes, and aft-end seal slots. Supplied with dimensional inspection report (CMM data) and EN 10204 3.1 alloy chemistry certificate. TBC (thermal barrier coating) applied where required by OEM specification. Compatible with both gas and dual-fuel combustion systems. Critical high-cycle parts; Gulf Union Ozone recommends 10% safety stock at each Saudi plant for unplanned-outage coverage.

Type 02

Nozzle Guide Vanes

First- and second-stage NGV segments in IN738 and Mar-M247 directionally solidified alloy; TBC-coated where required by OEM specification; for hot-section replacements at Saudi Aramco and SEC gas turbine overhauls. NGV segments are the highest-temperature stationary airfoils in the gas turbine and are subject to oxidation, creep, and TBC spallation in Saudi Arabia's high-ambient-temperature operating environment. Gulf Union Ozone supplies both new and OEM-licensed repaired/re-coated NGV segments with full dimensional and coating thickness inspection records. Compatible with GE Frame 6B, Frame 7EA, LM2500, LM6000, and Siemens SGT-400 turbines.

Type 03

Compressor Blades & Vanes

Axial-flow compressor rotor and stator blades in 17-4PH stainless and titanium 6Al-4V for inlet stages; profile-ground and shot-peened per OEM tolerances for Saudi turbine fleet maintenance. Compressor blades are critical for turbine efficiency; erosion and corrosion from Saudi desert sand and coastal salt air accelerate blade degradation. Gulf Union Ozone supplies full-stage blade sets for GE Frame 5, Frame 6B, Frame 7EA, LM2500, and Solar Centaur 50 turbines, with profile-grinding certificates confirming chord, thickness, and leading-edge radius within OEM drawing tolerances. Inlet guide vane actuator assemblies also available.

Type 04

Turbine Seals

Abradable brush seals, labyrinth seals and honeycomb seal segments for hot-section and compressor inter-stage sealing; reduce leakage losses by up to 2% turbine efficiency. Brush seals use Inconel 625 bristle packs for compressor discharge and turbine inter-stage positions; labyrinth seals in abradable aluminium-silicon alloy for large clearance control; honeycomb seal segments in SS 316L brazed construction for LM2500 and LM6000 compressor and turbine stages. All seals supplied with dimensional inspection records. Replacing worn seals at each major overhaul recovers measurable heat rate improvement in Saudi power plant gas turbines.

Type 05

Igniter Plugs & Spark Igniters

High-energy igniter plugs and surface-discharge igniters for GE, Siemens, Solar and Rolls-Royce turbines; rated for full diurnal temperature cycle in Saudi outdoor gas plants. Igniter plugs are consumable items replaced at every borescope inspection (typically every 4 000 fired hours) and must be held as critical spares to avoid delayed start-up. Gulf Union Ozone stocks high-energy igniter plugs (1–4 joule) and surface-discharge igniters in Jeddah warehouse for immediate dispatch. Ceramic insulator and nickel or platinum-iridium tip materials available. Fully compatible with OEM ignition exciter units.

Type 06

Transition Pieces

Combustion transition ducts in HA-188 cobalt alloy and Hastelloy X; connect the combustion liner to the turbine first-stage nozzle; critical high-temperature parts requiring exact OEM geometry match. Transition pieces direct hot combustion gases from the can-annular combustors into the turbine nozzle and must maintain precise exit-plane geometry to ensure uniform temperature distribution across the NGV. Gulf Union Ozone supplies transition pieces for GE Frame 5, Frame 6B, and Frame 7EA turbines — the most common models in Saudi Arabia power and gas plants — with full CMM inspection and EN 10204 3.1 alloy certificates. TBC coating applied where OEM-specified.

Frequently Asked Questions

Gas Turbine Spare Parts in Saudi Arabia — Common Questions

How do you ensure dimensional compatibility of gas turbine parts with OEM tolerances?

Gulf Union Ozone sources gas turbine parts from manufacturers with active FAA Part 145 (or EASA Part 145) approvals or from OEM-licensed repair shops. Every part is shipped with a dimensional inspection report (CMM data) confirming that critical features (blade chord, trailing edge thickness, cooling hole diameters, pin boss geometry) are within OEM drawing tolerances. For Saudi Aramco turbines, we also provide the alloy chemistry certificate (EN 10204 3.1) against the required superalloy spec (e.g. IN738 per AMS 5891).

What are the most frequently replaced hot-section parts on GE Frame 6B turbines in Saudi Arabia?

The highest-turnover hot-section parts on GE Frame 6B turbines in Saudi Arabia are (in order): combustion liners (typically replaced every 24 000 fired hours), transition pieces (same interval), first-stage NGV segments (replaced or repaired every 12 000–24 000 hours depending on firing temperature), fuel nozzle assemblies (inspected every 8 000 hours, replaced as needed) and igniter plugs (replaced at every inspection, typically 4 000 hours). Saudi dust and humidity accelerate oxidation and TBC spallation; Gulf Union Ozone recommends maintaining a 10% safety stock of each in the Saudi plant warehouse.

Can Gulf Union Ozone supply parts for Solar Turbines units used at Saudi Aramco gas plants?

Yes. Gulf Union Ozone stocks and sources spare parts for Solar Turbines (a Caterpillar company) models including Centaur 50/60, Taurus 60/70 and Saturn 20/C28 — all widely used at Saudi Aramco gas-oil separation plants (GOSPs) and pipeline booster stations. Parts include combustion liners, IGV actuators, compressor blades, igniter plugs and fuel control valves. We also source Solar Turbines OEM parts through authorised distributors and can confirm availability within 48 hours of a request.
