Supraflow High Volume Tapping Tee

Presented by:

Energy Materials and Controls


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.


Supraflow Solution

Intrinsically safe and easy PE main branching operating up to 150 psi.

No other solution offers live gas-free 4"-8" branching on 4"-18" main for:

• Main Connections• High Flow Services • Large diameter by-pass installations

Large Tapping Tee is simple and quick using ultra light drilling equipment.

The exclusive tubular cutter retains the coupon and shavings.


Supraflow Solution2010 - Developed by Grupo Torre in Barcelona, Spain, a 136 year old company.

Why?

• In response to growing concerns in Europe over the lack of cost-efficient large diameter PE hot tapping systems.

• Safety issues over the potential damage that squeeze-off causes to PE pipes.

To Date…

Color Coded System

Tool Case



3 step closure design creates permanent air tight seal.

1. O ring on internal cutter seat acts as primary seal.

2. Two additional o rings in the tee’s head.

3. PE cap with o ring finish installation.

After tapping is complete, cutter is withdrawn to the top of tee.


Supraflow Solution – Negligible Flow Restriction

Tested for pressure loss values. Test was performed at several different flow speeds, up to 35 ft/sec which is maximum available for this kind of tests. Drop was less than 0.1 psi.


Supraflow Solution - Testing

Fully meet ASTM 02513 requirements.

Tests performed according to ASTM 02513 and test conditions following ASTM 01598, and assembly electrofusion following procedure qualified under 49CFR 192.283.
