Current through Vol. 42, No. 6, December 2, 2024

Section 380:25-5-13 - Steam gages

(a) Each steam boiler shall have a steam gage with a dial range graduated to not less than 1.5 times the set pressure of the safety valve, connected to the steam space or to the steam connection to the water column. The steam gage shall be connected to a siphon or equivalent device of sufficient capacity to keep the gage tube filled with water and so arranged that the gage cannot be shut off from the boiler except by a cock placed near the gage and provided with a tee or lever handle arranged to be parallel to the pipe in which it is located when the cock is open.

(b) When a steam gage connection longer than 8 feet becomes necessary, a shut-off valve may be used near the boiler provided the valve is of the outside-screw-and-yoke type and is locked open. The line shall be of ample size with provision for free blowing.

(c) Each boiler shall be provided with a 1/4 inch or larger nipple and globe valve connected to the steam space for the exclusive purpose of attaching a test gage when the boiler is in service so that the accuracy of the boiler steam gage may be ascertained.
