Ultra High Pressure Water Jetting - UHP WJ

UHP WJ is a great tool for removing light to heavy corrosion, old coatings, cleaning, demolition of concrete and cutting steel & concrete.

Our UHP WJ units have a pressure ratings to 37,500 PSI (2500 Bar) and are fully portable, small and compact for those hard to get to places and projects.

UHP WJ has advantages over dry abrasive blasting that include no dust, less noise, less site waste, less cleanup, less encapsulation and in most cases quicker and cheaper results.

UHP Water Jetting applications include: 

  • Hydro-demolition
  • Surface preparation for coatings application
  • Corrosion/rust removal
  • Pipe cleaning & descaling
  • Floor, road & car park cleaning
  • Road texturing & line removal
  • Tank & vessel cleaning
  • Heat exchange tube cleaning
  • Underwater cleaning & cutting

Our operators are certified and trained to the current standards.

Safety, environmental compliance and quality is our ultimate goal.

For UHP Standards information go to NACE WJ-1, WJ-2 WJ-3 & WJ-4.

The four degrees of surface cleanliness achieved by waterjet cleaning are addressed in separate standards as follows: Clean to Bare Substrate (NACE WJ-1/SSPC-SP WJ-1 [WJ-1]), Very Thorough Cleaning (NACE WJ-2/SSPC-SP WJ-2 [WJ-2]), Thorough Cleaning (NACE WJ-3/SSPC-SP WJ-3 [WJ-3]),     and Light Cleaning (NACE WJ-4/SSPC-SP WJ-4 [WJ-4]).

Thermal Metal Spray

The process has many names, Thermal Spray, Metallising, Hot Zinc Spray or Arc Metal Spray, what ever the name, the process signifies superior quality and performance.

The basic concept of this process is to arc two wires together and then push high volume air behind that arc to disperse the molten arc into fine molten partials that are then propelled onto a pre-prepared substrate where the particles solidify.

Thermal Metal Spray has come into a new era with new technology pre-alloyed wires for longer life, more resilient coatings and higher deposition application equipment for larger on site projects.

Thermal Metal Spray provides coatings far superior to conventional coatings and has proven and documented extra long term protection & performance history.

Zinc & aluminium and alloyed thermal spray coatings can be designed to provide any service life required, from short term 5 yrs to long term 200 years+.

Thermal Metal Spray can be applied in wider and more diverse climatic conditions than conventional paints and can even be applied during the abrasive blasting process.

The coating is instantaneously ready for service after application. ‘No more watching paint dry!’

Thermal metal spray can be used for a wide variety of applications from providing galvanic protection, corrosion protection, wear resistance, non-skid, base metal thickening & reclamation.
