Chemical and Petroleum Engineering Aims and scope

Features of the change in properties of pipe steel of strength category Kh80 during strain ageing and its effect on weldability are studied. It is shown that depending on the degree of plastic deformation with ageing of basic metal there is a change in the rational range of cooling rate in the temperature range of diffusion transformation of austenite (w 8-5) of the area near the seam (ANS) of the heat affected zone (HAZ), providing the required set of mechanical properties and in particular failure resistance. This should be taken into account in developing welding repair and restoration technology for main gas pipelines made of high-strength steels, previously in operation.
