The aim of this article is to quantify the loads exerted by heavy-duty vehicles when crossing over buried pipeline. This problem arises in connection to the question pertaining to the use of protective sleeves (casings) applied to gas pipelines in re

An investigation was made into mechanical and fracture – mechanical properties of seamless pipe O 525/8.5 mm from CSN 413126 steel and axially welded pipe O 508/6.3 mm from L360NE steel. The results pointed on the dominance of the welded pipe in ba

The defects in the weld can be defined as irregularities in the weld metal produced due to incorrect welding parameters or wrong welding procedures or wrong combination of filler metal and parent metal. A lack of root fusion (LRF) is one of the weld

A controlled overloading of some structures containing sharp defects can lead to improvement of the integrity of the structures due to blunting the defect tip, enlarging the plastic zone and giving rise to residual compressive stresses at the defect

For standard fracture mechanical tests flat specimens (principally CT or SENB) are required. When investigating fracture mechanical properties of thin – walled pipes this brings about a problem because it is necessary to straighten pipe bands. This
