Load Testing for Pipe Hangers and Systems
On-line Load Testing and Load Adjustments!
Do You Have?
- Bottomed out spring hangers
- Sagging high temperature steam lines
- Broken hanger components
- High energy steam lines "jumping" during startup/shutdown
High energy steam piping systems frequently operate at temperatures in excess of 900 deg. F. These same systems are also typically exposed to variable support loading as a result of unit thermal cycling.
The presence of these two items, when coupled with the standard mid-sized constant spring hangers, routinely result in increased system stresses, permanent creep deformation and reduced system operating life, with steam leaks and major failures possible.
On-Line Load Testing
Fastorq has the methods and tooling to measure piping loads and spring hanger loads under plant operating conditions. This on-line load testing will identify present loading conditions and what further evaluations may need to be performed i.e. NDT, "As Exists" stress analysis.
On-Line Load Adjustments
After proper evaluations have been performed, the hydraulic tooling is used to load adjust and monitor field adjustment made to the hanger system. This allows the correct load to be applied at the "HOT" operating travel position.
Associated System Testing
Fastorq tooling is also used for weighing and adjusting boiler headers and components that directly influence piping loads and movement. These problems are frequently associated with symptoms of more severe problems which need exploration through "As Exists" analysis.
An integral part of Fastorq's capability is a close working relationship with our clients and their technical staff. As a specialty service contractor, we have the unique capability of performing in-service load determination and testing of spring hangers and other support systems. Such testing can also detect non-functional support members that show no outward sign of distress of failure.
