Case Study: UPM Changshu Mill achieves 20+ years of reliable PM 2 performance with Valmet Press Roll Cover GG

UPM Changshu Mill delivers 20+ years of stable PM 2 performance with Valmet

UPM Changshu Mill faced a significant challenge on its PM 2 paper machine, where extreme temperatures exceeding 80°C and harsh conditions caused traditional roll cover materials to deteriorate quickly, threatening stable paper transfer and reliable dryer performance. To address this, the mill turned to vendor Valmet and installed the Valmet Press Roll Cover GG.

Valmet's solution was the Press Roll Cover GG, a product engineered for heat resistance, anti-stickiness, and corrosion resistance. After twenty years of uninterrupted service, an inspection confirmed the cover was in outstanding condition with no delamination or cracking, eliminating the need for premature replacement. This reliability from Valmet significantly reduced downtime for UPM Changshu Mill and ensured the smooth execution of their maintenance plans.
