Abstract
The paper presents comparative test results of X10CrMoVNb91 steel collector samples. The influence of repeated heat treatment on the properties of the material was investigated, and the samples underwent a different number of thermal cycles. This material is most often used for pipes and pipe connections resistant to high pressures and temperatures. Steel is characterized by high thermal strength properties, which is why it is used in thermal power plants for superheater pipes, collectors as well as for high pressure steam pipes. It can be used even at high temperatures up to 600°C. The aim of this paper is the behaviour of the material during repeated heat treatment, which often occurs during the installation of the pipeline, and is caused by the repair of defects in the welded joint, incorrect installation of the pipeline and similar procedures.
