But the standard, BS EN 10311, dictated that you couldn't just swap steel sizes without recalculating the joint geometry. The bolt holes in the splice plates were drilled for a standard section. When the contractor forced the larger beam into the standard plates, the bolts didn't sit flush. They were eccentric.

In the world of industrial engineering, pipeline construction, and fluid transport, the integrity of a system relies heavily on its weakest link—often, the joints. For professionals working with steel pipelines across Europe and beyond, one standard stands out as the definitive code for joint qualification and assembly: .
