Aqua Milling / Hydro Milling – Internal Tube & Pipeline Cleaning

Saudi Hydrodynamics Co. Ltd. (Saudi Hydro) offers advanced Aqua Milling / Hydro Milling services for the internal cleaning of tubes, heat exchangers, fin-fans, condensers, and pipelines across the Kingdom of Saudi Arabia.

Our systems combine high pressure, high flow, and specialized tooling to remove hard deposits, polymer buildup, and scaling—restoring full flow capacity and improving equipment performance without chemical or abrasive damage.

Aqua Milling for Tube Cleaning

For shell-and-tube heat exchangers, air coolers, and fin-fans, Saudi Hydro utilizes customized Aqua Milling nozzles specifically designed for tube bundle cleaning.

These precision-engineered nozzles, coupled with centralizers and cage assemblies, maintain accurate nozzle alignment and ensure 360° cleaning coverage inside each tube.

·         Our Aqua Milling system efficiently removes:

·         Scale, rust, and process deposits from exchanger tubes

·         Hard polymer or hydrocarbon fouling in fin-fans and coolers

·         Blockages and contamination without mechanical damage

The system is fully adaptable for varying tube lengths and diameters, achieving superior cleaning efficiency in significantly less time compared to traditional methods.

RDR System for Pipeline Internal Cleaning

For large-diameter process pipelines, Saudi Hydro deploys its proprietary RDR (Rotrojet Directional Rotational) Cleaning System, capable of cleaning pipelines up to 72 inches in diameter.

The RDR system uses a directional, multi-axis rotating jet pattern to achieve deep cleaning and uniform coverage along extended pipe runs.

It is highly effective for removing choked polymers, heavy deposits, and scaling within process and transfer lines.

High-Volume Hydro Milling Power Packs

Both the Aqua Milling and RDR systems are powered by high-capacity hydrojet power packs delivering 200 liters per minute at pressures up to 15,000 psi.

This high-energy output enhances cleaning efficiency and enables the removal of hardened materials and heavy contamination from large pipelines—the same energy source utilized in Saudi Hydro’s hydro-demolition technology for concrete removal.

Applications

·         Internal cleaning of process pipelines and transfer lines

·         Cleaning of exchanger and cooler tubes

·         Removal of polymeric or hydrocarbon deposits

·         Pre-commissioning and pre-inspection cleaning

·         Pipeline preparation before hydrotesting or gauging

·         Safety, Quality, and Compliance

All Aqua Milling and Hydro Milling activities are executed under Saudi Aramco, SABIC, and Royal Commission standards, supported by Job Safety Analysis (JSA), tool calibration, and operator certification.

The process is eco-friendly, requiring only clean water and producing no chemical waste, ensuring both safety and sustainability.

Nationwide Service Coverage

Saudi Hydro provides Aqua Milling / Hydro Milling services across all industrial regions of Saudi Arabia, including Jubail, Dammam, Yanbu, and other major production hubs.

Our mobile high-flow power packs and trained technicians allow fast mobilization and reliable performance for maintenance, shutdown, and pre-commissioning activities.
