Abrasive Jet Cold Cutting

There is no product known to man that cannot be cut with Abrasive Jet Cutting technology.
In explosive atmospheres, underwater or radioactive environments, Our Contract Cutting Service will use remote controlled systems operating at pressure up to 2750 bar to cut concrete, steel or composite structures to form access ways or for controlled demolition.

Case History:

During reclamation work at a disused chemical works six No 1.7 metre diameter steel storage tanks were found buried on the site. The tanks contained carbon disulphide in liquid and vapour form and they had been filled with PFA grout in an effort to make them safe. The requirement was to cut open the tanks remove the PFA grout and dispose of all the materials safely. Working in conjunction with Brock PLC, RGL devised a special frame on which to mount the remote controlled Jetnife cutting head and this was to be used in conjunction with a long reach excavator to remove the ends of each tank. Great care had to be exercised to void the danger of explosion during the setting up and cutting operations. As it was required to remove the end of each tank cleanly a 360 degree cut was made on each occasion and this was very successful. The entire project was completed successfully on schedule and without incident.

 

The 17m Long Reach Excavator is seen in position prior to the start of Jet Cutting.

 

 

 

 

Cutting in progress: By driving the cutting head through a complete 360° path it was possible to cut completely through the 1.7 Metre Dia. Tank and the PFA grout.

 

 

 

The close control of Abrasive Jet Cutting can be clearly seen by the clean 2.5 mm slot cut around the steel tank.

 

 

 

 

Each end Cap was removed as shown, this gave the main contractor access to excavate the PFA grout in safety.
