Sealing of Threaded Joints in Gas Pipeline Installations

The problem of gas leaking on threaded joints sealed with hemp in home metering and control units (MCUs) occurs in daily installer´s praxis. Same is affirmed based on leaking analysis provided in this paper. Basic objective of the paper is to investigate reliability and safety of sealing threaded joints in MCUs with sealing cord at different number of turns (from 6 to 10 turns) and at different working pressures (from 1 to 6 bar). Experimental work includes testing of sealing cord Loctite 55 with two material combinations (steel-brass, brass–aluminum) in threaded pipe joints of Whitworth form at temperature 24 °C
