Investigation of welded joints of long-term operated gas pipeline controllable rolled X70 steel

The complex properties (mechanical, microstructure, and electrochemical) of controllable rolling X70 steel pipes of the main gas pipeline with a diameter of 1420 mm after an operation for 20 years and emergency reserve pipe after a similar period of storage were studied. Taking into account specifie...
