Housing Extension
When moving the packer from one lateral to another, the lateral grouting plug is retracted in the Flexible Housing Extension.
The minimum length of the Flexible Housing Extension must be determined according to the deflated length of the lateral grouting plug, the size & model of the lateral packer.
To determine the minimum length of the Housing Extension, the following formulas can be used:
- For 6″ lateral packer: LHE=LGP
- For lateral packer 8″ & larger: LHE= LGP-12”
- (LHE: Length of Housing Extension,
- LGP: Length of Lateral Grouting Plug)
