Capabilities/Services
PIPE FREEZING
Pipefreezing is regarded by many engineers as one of the most efficient
and cost-effective methods of pipe isolation for maintenance programs - valve replacement, pipework modification, etc.
On call around the clock 365 days a year, Allied Flow Specialists, Inc. operatives carry out
projects throughout the world, regardless if it is a 20" heating main in a London hotel or a 4" chilled water line in a San
Francisco data center. AFS will be your solution to the isolation problem.
Capabilities Include:
- 1/2" - 48" line freezes up to 4000psi
HOT TAPPING
Hot tapping is defined as using an under pressure drilling machine to cut
a hole in an operating pipeline which allows for a new branch connection from the original pipe. This process is done without
any product leakage or interruption of flow. This method employs a tapping machine, a full-ported valve and pressure-containing
fitting attached to the existing pressurized system.
Capabilities Include:
- Sizes ranging from 1/2" to 12"
- Temperatures through 250 degrees
- Pressure through 300psi
SPECIAL APPLICATIONS
Line Stopping is a means of isolating a pipeline
where no valve exists. Various line stops and bypasses can enable repairs or modifications to be performed without a shutdown.
Capabilities Include:
- Sizes ranging from 1/2" to 12"
- Pressures through 300psi
- Applications for most products
- Complete services available
- Temperatures through 400 degrees
Flowmeter and Thermowells AFS can provide flowmeters and /or thermowells and install
your meters without interruption of service. A number of flowmetering and thermowell models are available for a wide range
of pipe sizes, temperatures, pressures and purposes.
BACKFLOW
Any connection or potential connection between the potable water supply
and a source of contamination is called a cross-connection. Irrigation systems, bypass arrangements or other temporary arrangements
through which backflow can occur are considered to be cross-connections. Backflow, the unwanted reverse flow of liquids in
a piping system, is created by two basic conditions backpressure or back-siphonage.
