High-pressure water jetting
Surface cleaning and preparation with high-pressure water jets
Learn more about this serviceWhat is high-pressure water jetting?
High-pressure water jetting (also known as hydrojetting or water jet) is a universal technology for cleaning, coating removal, surface preparation and concrete demolition. Learn how it works, what pressures are used, where it is applied and what to watch out for when selecting a contractor.
What does 3,000 bar mean?
An explanation of high pressure in water jetting — how pressure affects parameters, why the pressure figure alone is insufficient to assess equipment performance and when you truly need extreme pressure.
Benefits of water jetting
A comprehensive list of advantages and limitations of high-pressure water jetting — when it makes sense to use a water jet instead of blasting or chemical removal, what the method limits are and what you gain from hydrojetting on steel and concrete.
Environmental considerations of water cleaning
Why high-pressure water jetting is gentler on the environment than sandblasting and chemical stripping. Method impact comparison, wastewater handling and how greener technology helps companies meet stricter regulations.
Water jetting steel structures
A complete guide to steel surface preparation: abrasive vs water jet blasting, ISO 8501 cleanliness grades, anchor profile and removal of salts and flash rust before applying corrosion protection.
What is sandblasting?
Sandblasting is the common name for abrasive blasting; the blasting medium is not necessarily sand.
Mobile abrasive blasting
Mobile abrasive blasting takes the equipment to the site, not the responsibility for protecting its surroundings.
Dust control in sandblasting
Wet, enclosed or extracted blasting can reduce dust; “dust-free” is not an absolute description.
Sa 1, Sa 2, Sa 2.5 and Sa 3 preparation grades
Sa grades are visual steel-preparation grades for abrasive blast-cleaning under ISO 8501-1.
Surface preparation before corrosion protection
Coating durability depends on cleanliness, profile, salts, dust and the climate during application.
Industrial cleaning
Cleaning of industrial equipment, tanks and process systems
Learn more about this serviceHow heat exchangers are cleaned
A correctly selected cleaning method can restore flow and heat transfer without damaging the tubes.
How tubes and tube sheets are cleaned
Cleaning tube bundles and tube sheets requires accurate tool guidance and settings for the material.
How industrial tanks are cleaned
Tank cleaning is first a safety-controlled process; personnel entry is not the default solution.
Removing rubber linings and deposits
Removal of a rubber lining or deposit must be designed for its adhesion, substrate and the intended surface outcome.
Removing coatings and layers
The choice of old-coating removal depends on layer composition, substrate and the new-system requirement.
