- Currently in Poland, the most important legal act specifying the requirements and materials that can be used for the construction of gas installations in buildings is the Regulation of the Minister of Infrastructure on the technical conditions to be met by buildings and their location (Journal of Laws 2015 item 1422 as amended). It permits the use of seamless steel or welded steel carrier pipes, and threaded connections or copper pipes joined by brazing. Due to the fact that the Polish Standard PN-EN 1775:2009 (PN-EN 1775:2009) allows the use of corrugated stainless steel hoses as well as other materials, including plastics or stainless steel systems joined by crimping, as well as emerging inquiries of manufacturers of corrugated stainless steel hoses concerning the possibility of their use in Poland, an analysis of the possibility of using corrugated stainless steel hoses for gas installations in Poland was conducted. The article presents the provisions in force in Poland and in selected EU countries regulating the possibility of using corrugated stainless steel hoses in gas installations in buildings. Research was carried out to examine the most important, form the author’s point of view, characteristics of corrugated stainless steel hose systems, taking into account those properties that may have the greatest impact on their safety. The research was carried out on three selected systems available on the EU market. The properties tested were tightness, bending capacity, internal pressure strength, impact resistance, dent resistance, tensile strength, fire tightness. The tests were carried out based on the methodology described in the Polish Standard PN-EN 15266:2009. All tests gave positive results. Finally, the feasibility of using corrugated stainless steel hose systems in gas installations in buildings was assessed, and additional requirements to be met by these systems were proposed.
