Retubing & tube replacement for boilers of all sizes. IB&M specializes in the retubing of firetube boilers, watertube boilers, superheaters, pre-heaters, heat exchangers and other pressure vessels. Boiler tubes must be able to endure extremely high temperatures, pressures, and potentially wide fluctuations in demand depending on the application.

Proper Pressure Settings for Residential Steam Boiler. The fact that the gauge reads zero seems to have no effect on performance but is still seems very strange. I originally set the P-Trol at 1 psi (Diff) and 1 psi (Main). I changes it tonight to read 1 psi (Diff) and 2 psi (Main) but still no reading on the gauge. Pictures:

Oct 01, 2017 · Pressure gauge is the fitting that measures steam pressure inside the steam boiler. The Bourdon tube is the most common pressure gauge used on a boiler. The Code specifies that a pressure gauge should be installed on the steam space and provided with a shutoff cock and a siphon which develops and maintains a water seal, protecting direct contact of live steam with the Bourdon tube.

DIY Steam Engine Boiler. The pressure cooker has a pressure gauge on it also. The Agricultural extension office will test your gauge to ensure it is accurate (for food safety purposes) This calibration should be done annually, for food preservation and I would suggest you get it checked BEFORE you modify your boiler,

High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.

My pressure gauge was kaput. giving me negative pressures or pressures reaching 20 psi within 10 minutes of the boiler running. This gauge, except for being a smaller diameter, is the same as my old gauge. At first I thought it was not working. gauge hardly moved at all during boiler operation. so I purposely ran the boiler for a longer time.

Hi there, I've been having high boiler pressure (between 2.5 to 3.5 bars) for over a week now. We had a plumber come in a couple of days ago who drained the central heating circuit, added two bottles of inhibitor and filled it back up so that the boiler showed 1 bar pressure.

On the right is the 55 gallon barrel, modified to use as a low pressure steam boiler. As you can see, I welded two black iron pipe nipples to the barrel, to be used for filling and also for the sight glass. Attached to the one at the bottom is a 90 degree fitting, and a 'T' is attached to the top.

The American Society of Mechanical Engineers (ASME) requires all boiler fittings to be made of materials that withstand the pressure and temperatures that boilers are subject to. All of the boiler fittings discussed are important and must be operated and maintained properly to operate a boiler safely.
