Frequently Asked Questions (FAQs)
Find answers to common technical queries regarding specifications, selection, calibration, and delivery.
Live steam temperatures (often 150°C to 350°C) will distort or anneal the gauge’s bourdon tube if allowed to enter directly. A pigtail or U-type siphon traps steam which condenses into water, forming a cool hydraulic barrier that shields the gauge internals from extreme heat.
Under Indian Boiler Regulations (IBR), the maximum scale of the boiler gauge should generally be approximately double the normal working pressure of the boiler, with the maximum permissible working pressure prominently marked in red.
Yes, we provide IBR approved test certificates along with our boiler pressure gauges.
