Popis:	Experimental studies were carried out and causes of emergencies with gas pipes in protective sleeves used in construction of gas pipelines were identified. Protective sleeve design has been developed that excludes deformation or destruction of gas pipeline during groundwater freezing in the annulus. Model tests of polyethylene gas pipeline in steel casing, using polyethylene foam as an element that compensates expansion of water during freezing, showed complete exclusion of deformation of gas pipes during freezing. Test results of developed designs of protective casings showed the possibility of widespread use to improve reliability and safety of gas supply.
