Abstract
Welded joints attitude of construction steel pipes is evaluated after tracing the bending static stress cycle in a technological process steam environment. A program is run, which envelopes further deformation in aggressive environment exposure, mechanical trials, and metallographic examinations. The results showed different effects to degradation, correlated to welded joints nature respective initial welded qualification. The results are used for preliminary long term exploitation capacity.
