Problem - Limited Options
Current methods for installing branch connections:
1. PE hot tapping2. Installing 3-Way Tees 3. Installing High Volume Tapping Tees

3-Way Tee
Installing a 3-way tee provides no flow restriction, however gas must be stopped using squeeze-offs.
Disadvantages:
Temporary bypass may be needed, adding labor and material cost.
Potential damage to PE at squeeze points, decreases pipeline integrity.
Larger excavations increasing reinstatement cost.
Lifting equipment to maneuver squeeze off tools in place.
Squeeze-off may not completely stop the gas.

HVTT
Disadvantages:
Only available in 2” and smaller Does not have enough flow compacity for larger projects.
The high-volume tapping tee (HVTT) is one of the easiest fittings to install a lateral connection.

PE Saddle Hot Tapping
Disadvantages:
Multiple steps required. Typically performed by a specialty trained crew. Requires a large excavation. Connection between new pipe and valve cannot be
pressure tested prior to energizing the new lateral.
Hot tapping through a branch saddle uses specialized equipment.
