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.

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.
