Case Study: Sappi’s Ngodwana Mill achieves improved boiler reliability with Valmet service agreement

Sappi’s Ngodwana Mill extends boiler reliability with Valmet over 7 years and zero tube leaks in 4 years

Sappi's Ngodwana Mill, an integrated pulp and paper mill in South Africa, sought to improve the reliability and availability of its three boilers to support its aggressive development and production capacity goals. To meet this challenge, the mill entered a long-term service agreement with vendor Valmet for comprehensive boiler maintenance and shutdown operations.

Valmet implemented a tailored service agreement focused on preventive maintenance, including regular inspections, shutdown planning, and timely execution of work. This solution ensured the boilers' performance met all targets, with a key result being no tube leaks in four years. The partnership with Valmet, which involved a dedicated team and extensive planning, successfully executed major upgrades during shutdowns, leading to significantly improved boiler reliability and availability.
