The failures in gas and oil pipelines are a dangerous and unpredictable source of environment contamination. Major trend in their preventing is to improve the reliability of used steels and their welded joints. The Institute of Metal Science has developed steels of third generation (nitride strengthened) for gas and oil pipelines. Compared to their conventional analogues they possess by 25% higher strength and at the same time high values of specific elongation and impact strength, good weldability (Cequi < 0,46% as per API) with no subsequent heat treatment. The main part of the gas pipeline 'Russia - Bulgaria South' has been built by 46 000 t of them. During the past 20 years it has proved high reliability (with no failures due to the steel grade used). The lack of failures in the operation of the gas and oil pipilines is of great ecological and economical importance. The nitride strengthened steels are a promising material for the new transit pipelines that are to be built in the region.
