What is a high-pressure waterjet cleaning machine?

A high-pressure waterjet cleaning machine is an industrial pumping machine that is used to pressurize water up to 500-3000 bar and force it through a precision tungsten-carbide nozzle, which results in a narrow, high-velocity jet of water. Highly effective in removing rust, mill scale, heavy coatings, grease, chemical deposits and concrete deposits from metal, concrete and composite surfaces without the use of abrasive media or harsh chemicals or the potential to damage the underlying surface.

The result is a clean, inspection-ready surface that is ready for coating/commissioning or return to service at SSPC/NACE WJ-grade inspection. They are used in oil and gas, marine, construction, food processing and petrochemical industries. Being a China-based manufacturer, supplier and exporter, we are equipped with OEM and customized capabilities to satisfy industrial needs, and we also provide after-sales service, genuine spares and global shipping.

Pressure Range Guide – Which Machine Do You Need?

Key Features That Enhance Industrial Reliability

No machine leaves our facility designed for single-day operation; we engineer every unit for continuous, demanding use.

Up to 3000 bar output pressure — Enough force in a single pass to remove tough mill scale, heavy protective coatings and chemical residues from steel and concrete in even the most demanding environments, including refineries and offshore platforms.

Integrated safety systems — Pressure relief valves, anti-burst hose sleeves and dead-man controls – all comply with CE standards and are tested under strict quality control procedures before every shipment.

Corrosion-resistant construction — Frames, pump heads, valve blocks and manifolds are built using only high alloy materials to ensure longevity in corrosive environments, including saltwater exposure and chemical-heavy environments.

Portable and site-ready — Smaller trolley and skid-mounted models fit through standard door openings and narrow areas. Diesel models are fully self-contained – no mains power needed at remote or offshore sites.

Fully adjustable pressure and flow — Fine pressure control protects sensitive substrates; switch to full-pressure mode for maximum stripping power. Works with fan nozzles, pencil jets, rotating heads and flexi-lance attachments.

Modular accessory system — Extension lances, rotating pipe-cleaning nozzles to DN200 bores, and abrasive injection modules allow one platform to carry out both bulk cleaning and fine detail work accurately, supporting bulk requirement projects.

Industrial Applications We Serve

• Surface Cleaning / Pre-coating Preparation — Providing WJ-grade cleaned surfaces on steel and concrete, ready for painting and inspection.
• Pipeline & Tube Cleaning — Used to remove scale and blockages inside pipes up to 200mm bore using a rotating cleaning head, free from chemicals.
• Hydrodemolition — Non-destructive removal of concrete without causing damage to reinforcement steel, such as bridge decks, tunnels, and offshore structures.
• Ship hull and tank cleaning — Large-surface rotating heads cover the hulls quickly while the flexi-lance configurations reach confined tank interiors and bilge areas.
• Heat exchanger and vessel — Cleaning removes scale and fouling chemical deposits effectively from tube bundles and vessels without chemical dosing.
• Rust, paint, and coating removal — This operation removes the underlying layer by stripping protective layers, rust and mill scale from structural steel and concrete.

How the Waterjet Cleaning Machine Works: Step by Step

• Water intake and filtration —The machine draws water from the water supply through an inlet filter. The filter traps dirt and other particles before they reach the pump or nozzle, helping to protect the pump from damage and keep the water pressure consistent.
• High-pressure pump stage — The filtered water enters an intensifier or direct-drive pump, specially designed by our factory. The pump raises water pressure to a desired value from 500 to 3000 bar.
• Pressure delivery and safety control — The high-pressure water flows through strong, pressure-rated hoses. Automatic relief valves open when the pressure is excessive, providing protection to the operator and machine.
• Nozzle selection and jet formation — Different spray patterns (fan, pencil jet, rotating or flexi-lance) are created by a durable tungsten carbide nozzle to suit the cleaning task and surface geometry.
• Surface impact and cleaning action — The powerful water jet is used at high velocity to remove rust, scale, paint, coatings and grease from surfaces. It thoroughly cleans the surface without damaging the base material for subsequent work.

Why Choose Us as Your High-Pressure Waterjet Cleaning Machine Manufacturer & Supplier

Shenyang Reliable Technology is a reputable manufacturer & supplier of high-pressure waterjet cleaning machines, combining in-house pump engineering capabilities with direct export. Maintenance contractors, OEM partners, wholesalers and distributors always interact with the factory, not with a trading intermediary, which means we ship the true factory price terms, the quickest technical answers and the best accountability for every machine.

Downtime is costly, and surface preparation quality is often a contractual specification, so the machine must come through with a performance that is worth the money in industrial cleaning. Our design and construction of the high-pressure pumps and core components enable us to understand how a unit will perform in continuous duty on offshore, refinery and shipyard substrates and match pressure, flow and nozzle configuration to a buyer’s specific contaminant and substrate. That engineering depth is what keeps performance stable and spare-parts costs predictable.

As a global supplier, we also cooperate with the commercial side procurement teams, adding value: steady lead times, export-quality crating, comprehensive documentation including CE certification and test reports, and lifecycle service. Each unit undergoes a pressure test at its full operating pressure before shipment and is supported by genuine spare parts availability globally.

For distributors and wholesalers who are planning to build a long-term line of cleaning equipment, this combination of own-factory production, wholesale price, customization, CE Manufactured and consistent global distribution makes us an equipment partner rather than a one-time vendor.
