Attaching CMT Tubing Centralisers

Step 20) Install Centralisers

Place the centralisers over the CMT Multilevel System tubing at the desired depths. Centralisers are generally placed along the CMT tubing at intervals ranging from every 5 to every 15 feet. Attach the centralisers securely to the CMT tubing using two stainless steel clamps (Figure 27).

The CMT well is now ready to be inserted into the borehole.

Note:

Solinst has developed special tubing centralisers that ensure that the tubing is centred in the borehole during well construction. The fins on the centralisers are low-profile to prevent them from obstructing the tremie tube, or sand and bentonite pellets poured from the surface. Centralisers are available as 5.5″ OD, 4.4″ OD, and 3.5″ OD.
