<p>A system for pressurised fluid flow comprises a drilled element 100 with a primary bore 110 and a secondary bore 120 with an intersection 130 between them. The drilled element 100 is loaded by at least one loading element which provides a loading force at an end of the primary bore 110. A stress relief layer 140 is provided at a first face of the drilled element 100 and the loading force is provided through it to the drilled element 100. The stress relief layer 140 extends underneath the intersection 130, and the intersection 130 is sufficiently close to the first face of the drilled element 100 that, in use, the loading force provides compressive stress in the drilled element 100 at the intersection 130.</p> |
