SERVICES

HYDROJETTING
​

Surrotec offers a specialized hydrojetting service which is also called ultra-high pressure water blasting. By hydrojetting we easily and environmentally friendly remove various types of coating and debris from both metal as well as concrete surfaces.

​

Some examples of where we apply our services:

 

Storage tanks:

Removing the coating from both the outside and inside wall, the roof and the bottom of tanks;

Removing salts and chlorides from the tank bottom and wall in preparation for the application of a new coating;

 

Ships:

To remove the coating and / or heavy fouling on the skin;

 

Bridges:

To remove the coating;

 

Pipelines:

Applicable for both the outside and the inside;

 

Floors and ceilings:

Ideal for removing a hard floor or ceiling coating;

 

Miscellaneous:

Locks, windmills, boilers, and in many other locations both onshore and offshore;

 

Your advantages when applying our ultra-high pressure waterjet services:

 

  • Dust-free blasting so that people and the environment are not exposed to dangerous particulate matter;

  • Reduction of waste and related costs.

  • The waste water can be extracted, collected and purified by our water purification, leaving only the paint as waste;

  • No risk of sparking, so the objects to be blasted can remain operational in many cases;

  • Possibility to work in an ATEX zone;

  • Very powerful technique where almost all types of pollution and coating types can be removed;

  • An affordable service by our certified and skilled employees;

​

HYDRODEMOLITION
​

By means of water jetting at a pressure of 1100 bar with a volume of 340 liter per minute. This in combination with a robot which has been developed specially for this application is a method to selectively remove damages inside concrete surfaces. We hereby apply high pressure pumps of max. 750 kW.

​​

Depending on the hardness of the concrete, the applied reinforcement, the demolition depth to be achieved and the applied capacity of the high-pressure pump, yields of between 0.5 and 1.0 m3 / h can be achieved. Hydrodemolition is often used in parking garages, viaducts and tunnels.

 

Your advantages when applying hydrodemolition:

 

  • It is a fast and cost-saving method; 

  • It only removes affected concrete;

  • Prevents cracks in existing concrete;

  • The surface remains clean and rough, so that new concrete adheres well; 

  • Existing reinforcement remains intact (can even be demolished under the reinforcement);

  • Service personnel are not exposed to vibration or dust formation;

  • The noise level is lower than traditional methods;​​

COLD CUTTING

 

Cold cutting is a process at which water, with addition of some garnet, is put under high pressure and through a nozzle is concentrated on the material to have an erosive effect.

Surrotec provides this service both on tank farms, (petro)chemical sites as well as offshore.  

​

With our mobile installations it is possible to carry out the cutting work at any desired location.

 

Some examples of where we apply our technique:

  • Cutting of tank walls and bottoms

  • Cutting through piping

  • Cutting through barrels and columns

 

Your advantages when applying water jet cutting / cold cutting:

 

  • It can be applied in a potentially explosive environment, which therefore happens a lot.

  • It is a fast and cost-saving method.

  • In the water jet cutting process there is no heat input into the material.

  • This makes water jet cutting ideal for parts where the structure of the material may not change.

  • Depending on the thickness and conditions, it is possible to cut very accurately with water jet cutting.

  • In addition, there is virtually no burr when cutting and the finishing of the cut is therefore ideal for subsequent welding.
