Contemporary approaches regarding to infrastructure are
more and more directed to new materials development for natural gas and other installations. The
most recent development and application of the new materials pertain to sealant materials for
sealing of threaded joints in gas pipeline installations and installations for other media. Based
on provided analysis, gas leaking on threaded joints in home metering and control units sealed
with hemp was affirmed. Considering that in practical work in the case of hemp, sealing threads
are made by a thread tool and during threading, the tool lubricates, the influence of impurities
on sealing with anaerobic sealant compounds has been tested. Experimental work includes testing
of three different anaerobic sealing compounds with three material combinations in threaded pipe
joints (steel-brass, brass-brass and brass-aluminium) on three different temperatures (-20
degrees C, 25 degrees C and 100 degrees C).
