Tensile Strain Capacity
The tensile strain capacity of a pipeline is controlled by the tensile strain limit of the girth welds which tend to be the weakest link due to the possible existence of weld defects and often deteriorative metallurgical and/or mechanical property changes from welding thermal cycles. The girth welds here refer to the entire weld region, including the deposited weld metal, fusion boundary, and the heat-affected zone (HAZ).
CRES is a world leader in the assessment of tensile strain capacity. Our integrated approach from welding process design and specification to advanced multi-scale mechanics ensures the necessary tensile strain capacity is achieved in the most cost-effective and reliable manner.
