‘More energy-efficient steam systems’ are the promise of the new STS17.2 steam trapping station just launched by Spirax Sarco in an expansion of its Quick-Fit steam trap range.
The STS17.2 comprises isolation valves, a steam trap connector with strainer, and a check valve, in ‘a sleek modular body’, supported by a 10-year warranty.
Spirax Sarco says: “A steam trap can now be replaced in minutes instead of hours, enabling steam systems to be kept at peak performance and energy efficiency, with plant downtime also reduced significantly.” The company explains that, ‘traditionally, steam traps are welded or screwed into the pipeline’, meaning considerable work is needed to replace them, ‘potentially resulting in an underperforming trap that requires maintenance being left in place ‘for a significant period’ until safe access can be arranged.
The STS 17.2’s single-piece body is also said to ‘virtually eliminate the potential leak paths caused by screwed connections that conventional steam trapping stations and on-site fabricated installations typically suffer’. “The new steam trapping station’s innovative, leak-free, stainless steel body helps steam system operators to further reduce carbon emissions,” explains Paul Mayoh, Spirax Sarco product manager. “Total ownership cost is lowered via the use of high performance stainless steel components, ensuring long and trouble-free operation.”
Apart from the steam traps, no other components need to be specified or purchased, while the inclusion of lockable handles on the isolation valves helps to ensure that maintenance can be carried out safely ‘by minimising the possibility of accidental operation’. Internal parts, including the ball valves, check valve, and strainer screen, can all be replaced easily.
A new option with the STS17.2 is the double isolation adapter, which Spirax Sarco says ‘provides the added security of two upstream isolation valves’, and allows replacement of steam traps whilst the system is live.
The STS17.2’s compact design allows it to ‘squeeze into positions too tight to accommodate traditional steam trapping stations built from separate components’, while other options available include an automatic steam trap monitoring facility, and strainer blowdown valves to further reduce maintenance.
Spirax Sarco adds: “Although there are several connector steam traps available, selection here is further simplified by considering ‘thermodynamic’ for mains drainage, and ‘float’ for heat exchanger applications. Steam traps can be changed or maintained quickly, with only two bolt connections, without breaking the pipeline.”
The new trapping station is suitable for clean steam and filtered applications such as hospital sterilisers. No sizing or selection is required for the STS17.2, which is designed for all steam main applications of up to 17 bar g DN150 line size.
