<br /> OTHER CONSIDERATIONS
<br /> Testing:
<br /> The recommended field test procedure for Red Thread 11 pipe is Pipelines operating at low pressures subjected to severe thermal
<br /> to conduct the following cyclic pressure test. The piping system cycling should be tested at 1','^times the piping system pressure
<br /> should be pressurized to 11/times the operating design pressure, rating.
<br /> ten times. The tenth pressurization should be maintained for 1-8
<br /> hours and the line inspected for leaks. Do not field test until all supports, anchors and guides are
<br /> properly installed.
<br /> Field test pressures are limited to 11;2 times the maximum cyclic
<br /> rating of the lowest rated component in the system. The maximum Water Hammer:
<br /> test pressure should not exceed 450 psig for any system without Care should be taken when designing an FRP piping system to

<br /> valves should be considered.
