PL122295U1 - Gas connection with insulation, especially for domestic gas network - Google Patents

Abstract

The subject of the utility model is a gas connection with insulation, especially for the home gas network. The section of the bent steel pipe (1) has insulation (5) mechanically applied along the entire length of the pipe (1) before it is bent. The insulation (5) is made of a polyethylene tape braid with an overlap on the sealing substance layer. An additional insulation layer (5a) is applied on the pipe bend (1) on the insulation (5). The insulation layer (5a) is made of heat-shrinkable plastic. The insulating layer (5a) is a heat-shrink tape in the form of a braid. Braid with tape in the insulation layer (5a) is oblique with respect to the braid with polyethylene insulation tape (5). The pipe (1) at the end section (1b) of smaller diameter has a stop collar (2) rolled from welded material on the perimeter of the end section (1b) at the edge of the pipe (1), where between the transition section (1a) the diameter of the pipe (1) and the stop collar (2) is a known sliding nut (3) half-union. The pipe (1) at the other end (4) relative to the end section (1b) has circumferential notches (4a).
