Abstract

Un sistema de canerías comprende un primer y un segundo canos, que tienen un primer y un segundo extremos soldados entre sí, formando una soldadura circunferencial, y un material polimérico termorrecuperable, que comprende una pluralidad de orificios, los cuales se extienden a través del mismo, cubriendo la soldadura circunferencial. El material polimérico termorrecuperable puede incluir una superficie que tenga una cubierta adhesiva sobre si, dispuesta sobre la soldadura circunferencial. El aire atrapado debajo del material polimérico recuperable puede liberarse a través de la pluralidad de orificios durante la contraccion del material polimérico termorrecuperable. También, una porcion del adhesivo puede fluir a través de los orificios durante la contraccion del maten polimérico termorrecuperable.
