Gulf Union Ozone supplies a comprehensive range of sample conditioning equipment for process analyser connections, online quality monitoring, and regulatory sampling at oil and gas, petrochemical, power generation, and water treatment facilities across Saudi Arabia. Our inventory covers fixed and retractable sample probes in SS 316L, coil sample coolers and shell-tube sample coolers (water-cooled), packaged fast-loop sample systems, grab sample cylinders (150ml, 500ml, and 1L), sample conditioning panels (basic and multi-analyser), PTFE-lined sample transport tubing, and Hastelloy C-276 components for corrosive streams — all designed to ISO 10715, ISA-77.44, and API 14.1 (natural gas sampling). ISO 9001:2015 certified (CR 4030570569). Same-day dispatch from Jeddah on stock items.

Gulf Union Ozone carries six sample conditioning product families to ISO 10715, ISA-77.44, and API 14.1 standards. All wetted components are manufactured in SS 316L as standard, with Hastelloy C-276 available for corrosive streams.
Fixed insertion sample probes in SS 316L for extracting representative process samples from pipelines, vessels, and stacks. Single-point and multi-point probe designs for gas, liquid, and steam sampling. Insertion depth from 100mm to 2000mm, available with 1/2-inch NPT or flanged process connections (ANSI 150# to 600#). Retractable (hot-tap) sample probes in SS 316L allow insertion and withdrawal under full process pressure (to 100 bar) without plant shutdown — essential for continuous online analyser connections at oil and gas facilities in Saudi Arabia. Automatic piston-type retractable probes with pneumatic actuator also available. Hastelloy C-276 probes for hydrogen sulphide, chloride, and acid service. Filter-tipped probes (10-micron sintered SS filter) for contaminated or particulate-laden streams.
Coil sample coolers in SS 316L — helical coil (sample fluid) inside a water-cooled shell — the simplest and most widely used sample cooling method for reducing high-temperature process samples to analyser-compatible temperature (below 60°C). Coil lengths from 1m to 10m; shell materials SS 316L or carbon steel. Annular (concentric tube) sample coolers in SS 316L for single-phase liquid samples requiring precise temperature control. Shell-and-tube sample coolers for higher sample flow rates or multi-stream duties. High-pressure sample coolers in Hastelloy C-276 for corrosive process streams at pressures to 350 bar. Air-cooled sample coolers (finned tube) for remote locations without cooling water. All coolers supplied with inlet and outlet temperature test points and SS 316L compression tube fittings.
Packaged fast-loop sample conditioning systems designed to ISO 10715 for minimum analyser lag time at refinery, petrochemical, and gas processing facilities in Saudi Arabia. Fast-loop systems continuously circulate a high-velocity sample stream from the process tap to the analyser house and back through a bypass return, achieving sample transport times under 30 seconds at distances up to 500m. Each packaged system includes: SS 316L coil sample cooler (water-cooled), pressure regulator (back-pressure type), dual-stage particulate filtration (10-micron and 2-micron), coalescing filter for liquid aerosol removal, bypass flow rotameter, needle valves for sample take-off and return, and PTFE-lined sample tubing connections. Mounted on SS 316L skid with weatherproof enclosure. ATEX Zone 1/2 components available.
Grab sample cylinders in SS 316L for spot sampling of liquid hydrocarbons, chemicals, and gases at process plants and custody transfer points across Saudi Arabia. Available in 150ml, 300ml, 500ml, and 1L capacities. Configurations: single-ended (one valve, spring-loaded floating piston for liquid sampling under nitrogen blanket), double-ended (two valves — one sample-in, one sample-out — for in-line flushing), and constant-pressure piston-type for volatile liquids and LPG. Pressure ratings from 69 bar (1000 psi) to 413 bar (6000 psi). Natural gas grab sample cylinders to API 14.1 — 150 bar working pressure, SS 316L, with CGA-fitting valves. Full dimensional traceability and hydrostatic pressure test certificates supplied.
Panel-mounted sample conditioning systems for multi-analyser and multi-stream applications. Basic sample panels: pressure regulator (back-pressure), SS 316L particulate filter (10-micron), flow controller (rotameter), and needle valves — all on a stainless back-plate with PTFE-lined sample connections. Full-featured multi-analyser sample panels: dual-stage filtration, coalescers, pressure and flow indication, solenoid valve switching for stream selection, back-pressure regulators for simultaneous multi-analyser feed, and heated enclosure option for high-pour-point or condensable streams. Field-mounted stainless enclosures (weatherproof, ATEX Zone 1/2 as required) for harsh outdoor environments at Saudi refinery and gas plant analyser shelters. Pre-tested and documented to ISA-77.44 before shipment.
PTFE-lined sample transport tubing (6mm, 9.5mm, and 12mm OD) in SS 316L outer jacket for low-adsorption sample lines — critical for trace-level analyser measurements of H2S, moisture, and reactive compounds in Saudi Arabia hydrocarbon streams. Unlined SS 316L tubing (6mm–25mm OD, 1/4-inch to 1-inch) for non-reactive streams. Needle valves in SS 316L (1/4-inch and 1/2-inch) for sample flow control and isolation. Back-pressure regulators in SS 316L and Hastelloy for constant sample line pressure maintenance. Particulate filter cartridges (2-micron, 10-micron, 40-micron) in SS 316L and Hastelloy housings. Coalescing filter cartridges (0.3-micron) for liquid aerosol removal. Diaphragm sample pumps (PTFE-wetted) for low-pressure sample take-off. Corrosion coupon holders for sample line corrosion monitoring.
All wetted components in SS 316L as standard; Hastelloy C-276 available for corrosive service. ISO 10715, ISA-77.44, and API 14.1 documentation supplied. ISO 9001:2015 QMS (CR 4030570569).

A fast-loop sample system continuously circulates a high-velocity stream of process fluid from the process line to the analyser house and back, maintaining a very short sample transport time (typically under 30 seconds) regardless of the physical distance between the sample point and the analyser. This is critical in refinery and petrochemical operations in Saudi Arabia where fast control loop response requires near-real-time analyser readings. Gulf Union Ozone supplies packaged fast-loop systems in SS 316L with coil sample coolers, pressure regulators, flow controllers, particulate and coalescing filters, and bypass rotameters — fully assembled and tested before shipment from Jeddah.
For corrosive process streams in Saudi Arabia oil and gas, petrochemical, and chlor-alkali facilities, Gulf Union Ozone recommends upgrading from standard SS 316L to Hastelloy C-276 for sample probes, sample coolers, and wetted fittings. Hastelloy C-276 offers superior resistance to wet chlorine, chlorinated solvents, hypochlorite, hydrogen sulphide, and high-chloride brines. For mildly corrosive streams, SS 316L with PTFE-lined tubing is often sufficient. We stock Hastelloy C-276 probes, coil coolers, needle valves, and tube fittings alongside PTFE-lined tubing in 6mm, 9.5mm, and 12mm OD. Contact us via WhatsApp 966550988062 for a material recommendation based on your process fluid.
