Round Boiler Gauges, MNPT, 1/2" display both the temperature and pressure of the water in a boiler. They measure water pressure in psi and kPa and temperature in °F and °C. Each features steel gauge case material for durability and copper wetted parts for corrosion resistance. Pressure accuracy: ±3-2-3% Temp. accuracy: ±3%.

Care must be given to ensure the proper selection of a water gauge. Special attention must be given to temperature/ pressure requirements and to the service media (i.e. water, steam, oils, chemical agents, etc.). Some items to keep in mind: • PRESSURE RATINGS may be influenced by limitations of the valve body, gauge glass, and gauge glass

Plumbers Edge Tridicator/Boiler Temperature and Pressure Gauge application is for hot water and steam pressure for boilers. The PE401 makes it easy to monitor your boiler's internal temperature and pressure level. The sensing element for temperature is a bi-metallic coil and the pressure is measured by a bourdon tube.

On this edition of the Boiling Point, Ritchie Ware joins shop foreman Jerry Hunley to learn step-by-step how to replace gauge glass. Jerry also explains how

1)Close steam and water valves on water column or gauge glass. 2)Open drain valve fully, drain and then crack steam valve and allow gentle rush of steam to pass through water column or gauge glass (>20 sec.) 3)Close steam valve, inspect and repeat until clean. 4)Close blow down valve and simultaneously open steam and water valves, slowly bringing back to normal operating level.

Once the Boiler pressure is raised to 10 kg/ cm2 (g) stop the pump and observe the pressure drop. Boiler Hydrostatic testing pressure gauge. If no leakage is observed to the satisfaction of the inspecting personnel, start the pressurizing pump. Raise the pressure gradually to 25% of the hydro test pressure and repeat the above steps.

2.References to pressure in this section are gauge pressure unless otherwise noted. 3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers:

The water tube boilers are mainly used for generating steam with high temperature as well as pressure. The internal structure of this boiler includes a tiny steam drum, small width tubes. The components of this boiler generate high-volume vapor for high-capacity applications.

We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
