Abstract: The behavior of the thick-walled pipeline under hydrogen corrosion is studied. The model example of thick-walled tube made of St. 20 steel with a region of local heating is considered. The internal and external pressures of hydrogenous medium are used as loading factors in the model example. The greatest effect of the value of internal pressure of hydrogenous medium on time to fracture is noted. Also, the faster decarburization in the region of high temperature is pointed out.

Keywords: hydrogen corrosion, destruction, front of decarburization, thick-walled pipeline.
