Conclusions
-
1.
It was found that the prolonged resistance to high temperatures of pipes made of ÉI579 steel with hydrogen under pressure inside the pipes depends on the initial hardness. The heat resistance of steel in hydrogen decreases considerably with decreasing hardness.
-
2.
The results obtained here on the prolonged resistance to high temperatures can be used as the initial characteristic for calculations and for determining the working life of parts of hydrogenization equipment operating at high temperatures and high pressures of media containing hydrogen.
