Every hour counts during critical maintenance operations. At SABIC Gelsenkirchen, J. de Jonge | Progresso. carried out the dismantling and reassembly of a reactor head and end plate, secured with 80 x 2-inch studbolts. With only five working days available, safe and precise execution was essential.

Five bolting specialists used HYTORC equipment and Simultorc technology, tightening four bolts simultaneously for balanced loading and faster execution. The combination of expertise, disciplined execution and the right equipment ensured completion within the shutdown window.
