Heavy Equipment for Modern Paper Mills
The pulp and papermaking process places immense demands on industrial equipment. From the harsh mechanical impacts of the woodyard to the highly corrosive chemical environments of chemical pulping and bleaching, paper mill components must be fabricated to exact tolerances using highly specialized materials.
At Openex Metal Fabrication, we offer full-scope manufacturing for pulp, paper, and tissue production facilities. Equipped with heavy plate rolling, massive 5-axis CNC machining, and automated submerged arc welding (SAW), we build and assemble the colossal tanks, drums, and heavy rollers that keep modern paper mills running smoothly.
Custom Pulp & Paper Equipment We Fabricate
🏭 Digesters & Pressure Vessels
We fabricate ASME-certified continuous and batch digesters, blow tanks, and evaporators. Utilizing explosive clad steel plates and Duplex stainless steels, we ensure ultimate protection against highly corrosive white and black liquors.
🪵 Woodyard Equipment
Barking drums and chipper chutes face extreme physical abrasion. We utilize thick, wear-resistant structural steels (like Hardox) and high-impact rolling techniques to build robust wood handling and conveying equipment.
⚙️ Large Machine Rolls & Cylinders
Yankee dryer cylinders, press rolls, and winding drums require immaculate surface finishes. We offer massive horizontal lathe turning and precision cylindrical grinding to ensure perfect runout and paper quality.
🌀 Washers, Thickeners & Towers
We manufacture the large, open vats, bleach towers, repulpers, and high-density storage tanks required in the screening and bleaching processes, employing certified strict clean-room welding practices for stainless steels.
Paper Mill Manufacturing Specifications
Pulp mills process massive volumes under immense pressure. We maintain strict testing standards and certifications to guarantee process safety.
