...Abstract Abstract The tubes of a stationary industrial boiler, 64 mm in diam and made of 1.25Cr-0.5Mo steel (ASME SA-213, grade T-11) failed by two different types of rupture. Noticeable swelling of the tubes in the area of rupture was revealed by visual examination. The tubes with slight...

... for the specified 1.25Cr-0.5Mo steel. This 305 mm (12 in.) diameter line ruptured due to HTHA after 16 years of service at conditions slightly above the Nelson curve limit for carbon steel, resulting in an expensive fire. The failed end of the pipe was jagged but undistorted, indicating a brittle failure ( Fig. 4a...

... for major oil refiners is failures or near-failures that can be attributed to insufficient alloy content in steels for hydrogen service. In one example, a carbon steel pipe section failed that was inadvertently substituted for the specified 1.25Cr-0.5Mo steel. This 305-mm (12-in.) diam line ruptured after...
