 Abstract
In this paper there is defined the functional role of fracture arrestors designed in order to be installed over natural gas transmission pipelines and there is made an original classification of these, while presenting the constructive features and the way of achieving a wide range of arrestor types. There is presented an analytical method for assessing the reinforcement effects of the application of fracture arrestors with continuous disposal over pipelines, method that can be successfully used while designing (determining the thickness of) fracture arrestors of this type.

 Rezumat
În lucrare se defineşte rolul funcţional al opritorilor de rupere destinaţi aplicării pe conductele de transport al gazelor naturale şi se face o clasificare originală a acestora, cu prezentarea particularităţilor constructive şi modului de realizare a unei game largi de tipuri de opritori. Se prezintă o metodă analitică de evaluare a efectelor de consolidare a tubulaturii conductelor prin aplicarea opritorilor de rupere cu dispunere continuă, care poate fi folosită cu succes la proiectarea (stabilirea grosimii) opritorilor de rupere.
