Application of anaerobic thread sealants in natural gas piplines

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 °C, 25 °C and 100 °C).
