Resistance of pipe steels to hydrogen embrittlement is an important indicator of their serviceability. Pipes are manufactured from steels of a wide strength range. With the strength increase, a susceptibility to hydrogen embrittlement in general increases. This regularity is usually true for steels in the as-received state; however, the long-term operation can increase hydrogen susceptibility even of low- strength steels. This is caused by the development of damage dissipated in the metal bulk with the formation of voids due to deformation caused by high-pressure recombined hydrogen in them. Implementation of the hydrogen-induced damage mechanism, associated with the formation of deformation voids, extends the strength range of pipe steels, which become prone to operational hydrogen embrittlement.

钢管的抗氢脆性能是其使用性能的重要指标。管道由各种强度范围的钢材制成。随着强度的增加，氢脆敏感性总体上增加。对于收到状态的钢材来说，这种规律通常是成立的。然而，即使是低强度钢，长期运行也会增加氢敏感性。这是由于金属块体中的损坏逐渐消散，并由于其中的高压重组氢引起的变形而形成空隙。与变形空隙的形成相关的氢致损伤机制的实施扩大了管钢的强度范围，而管钢变得容易发生操作氢脆。
