Ultra High Pressure Jet Washing & Hydroblasting

What Is Ultra High Pressure Jet Washing?

Ultra high pressure (UHP) jet washing uses a focused stream of water at pressures typically between 10,000 and 40,000 psi to clean, strip, profile, and even cut industrial surfaces. Unlike standard high pressure washing, UHP delivers enough energy to break the bond between stubborn scale, paint, rubber linings, refractory, and process residues and the substrate, while minimising damage to the base material.

UHP is ideal for:

• Removing hard deposits, scale, and process build‑up from tanks, vessels, and pipework.
• Surface preparation and profiling for NDT, welding, and recoating.
• Cold cutting of steel, refractory, and rubber linings in flammable or confined environments.
• Pre‑commissioning and turnaround cleaning where speed and precision are critical.

Our UHP Jet Washing & Hydroblasting Services

Thompson Group 365 provides a full range of ultra high pressure jet washing and hydroblasting solutions, tailored to your plant, vessel, or project.

Industrial Cleaning & Deposit Removal

Remove the toughest industrial build‑up quickly and safely, restoring flow, heat transfer, and capacity.

• Tank, vessel, and reactor cleaning – removal of sludge, scale, polymers, and process residues.
• Heat exchanger and boiler tube cleaning – restoring efficiency and preparing for inspection.
• Pipework and process line cleaning – pre‑commissioning, turnaround, and blockage removal.
• Hard deposit and scale removal from steel, concrete, and refractory surfaces.

Surface Preparation & Profiling

Prepare surfaces to exact specifications for NDT, welding, and coating, with minimal substrate damage.

• Surface profiling and scarification for paint, epoxy, and non‑skid coatings.
• Lead paint and hazardous coating removal with containment and vacuum assist.
• Weld seam preparation and NDT surface prep on vessels, reactors, and pipework.
• Concrete floor and deck cleaning, stripping, and profiling.

Hydroblasting & Cold Cutting

Use UHP water as a safe, cold cutting tool in high‑risk environments where sparks and heat are prohibited.

• Cold cutting of steel, refractory, and rubber linings – ideal for flammable atmospheres.
• Vessel and reactor head removal for inspection and repair.
• Precision cutting to pre‑marked lines and bevels, with minimal heat distortion.
• Simultaneous cutting through steel and refractory in one pass.

Automated & Robotic UHP Systems

Maximise safety and consistency with remote‑controlled and automated tools that reduce confined space entry.

• Automated lances and 3D tools for tanks, vessels, and reactors.
• Robotic manipulators and cutting tracks for precision surface prep and cutting.
• Remote operation from outside the space, improving safety in hazardous environments.
• Consistent, repeatable results that meet strict quality and safety standards.
