Gas Turbine Specialty Parts LLC (GTSP) was formed in 2015 with the goal to maximize the level of safety for your employees and increase turbine productivity and efficiency. We offer products that are new, cutting edge and add value while supporting a safer work environment.
Leak Detection System (Active)
The first product introduced was the flange “Leak Detection System” (patent pending). This cutting edge new product that achieves a high level of safety and provides an exact location – anywhere there is a potential leak of hydro-carbon and inert gases including ammonia, argon, carbon dioxide, ethane, helium, hydrogen, methane, natural gas, oxygen, propane, etc. GTSP’s System allows your employees to identify and locate leak(s) and perform repairs faster and more safely than ever before. In the case of natural gas fired power plants, a turbine compartment has been deemed to be a "Confined Space" by OSHA. In further support of OSHA, a major combustion turbine manufacturer has issued written guidelines and procedures prohibiting its employees and contractors under it direction from entry into an operating turbine compartment to perform leak detection or leak repairs. The “Leak Detection System” is easily installed over and completely surrounds the flange assembly. Each unit contains an external part that acts as a flag to indicate where there is a pressure release of gas or air. This system can be part of a maintenance strategy known as Condition Based Maintenance (CBM) to monitor the condition of piping flange connections and identify the need for repairs. Without question, it is better to find and fix small leaks before they turn into major leaks.
Using process air, the gold flag cap is forced off the red flag body at approximately 2-3 scfm and 7 psi allowing for a complete unobstructed flow. The gas detectors are not equipped to sense a 3 scfm leak but the red flag body would be visible after a shutdown and inspection of the turbine compartment. In addition, there could be air leak(s) that are not monitored which can also be detected. Air leaks could affect unit operating efficiency. Note that an approximate 150 scfm fuel leak would be equal to 10 LEL on gas detectors in a 7FA turbine compartment. A gas leak of this magnitude would either cause a unit trip or force an operator to trip the unit. The option for a pressure switch was set for 2 psi and would be used in a remote application such as a gas yard etc. The light on top could be set up to be seen by a control room operator. Consequently, your fellow employees should never enter an operating turbine compartment in the event of a gas or air leak. Shut down the turbine, shut off the fuel, and cardox or halon fire suppression system and then enter to check for leaks. Remember, SAFETY FIRST!
The second product, introduced is a newly designed “Open Air Thermowell”. The patent pending design is unlike the present thermowell design using a swagelock fitting to lock the thermocouple in place. Our design allows for thermal expansion of the thermowell and thermocouple while keeping the thermocouple solidly attached to the seating surface through startup & full operation. This eliminates damage to both the thermowell and the thermocouple. The immediate benefit will be fewer turbine trips along with greater availability, reliability and increased run time of the combustion turbine.
Gas Turbine Specialty Parts LLC remains focused to find solutions to issues that affect safety, availability, and reliability of combustions turbines and natural gas delivery systems.
