Pulp & Paper Mill FAQs
What strategies are available to address the rapid degradation of washer hoods and air pollution control equipment exposed to chlorine dioxide?
The high concentrations of ClO2 and other bleaching agents in the upper stages of the bleach plant are notorious for stripping the resin-rich interior barriers of Fiber Reinforced Plastic (FRP) equipment. To mitigate this, Plastech can provide field-applied fiberglass relining for scrubbers and washer hoods. This service involves a meticulous surface preparation process followed by the application of high-performance vinyl ester resins reinforced with C-veil or Nexus veil. By restoring the chemical barrier in situ, mills can extend the service life of these critical air pollution control assets without the prohibitive cost of full system replacement, ensuring that the facility remains in compliance with environmental air quality regulations.
How can mills maintain the structural integrity of aging bleach storage tanks while reducing the risks of chemical leakage?
Bleach tanks, typically constructed from FRP to handle sodium hypochlorite, suffer from chemical corrosion and mechanical stress over decades of operation. PlasTech Services Inc. offers specialized bleach tank linings and relining that utilize advanced composite knowledge to restore structural integrity. The process involves assessing both the chemical composition and the structural fatigue of the vessel before applying a new internal barrier. These systems are engineered to provide a robust shield against oxidative attack, preventing the leaks that could otherwise lead to hazardous environmental releases and costly emergency shutdowns.
For facilities facing critical production windows, what is the best approach for repairing or replacing high-diameter process piping?
The failure of a large-diameter process pipe can halt an entire production line, yet full replacements often take more time than a mill can afford during operational cycles. The recommended solution is rapid FRP pipe repair and installation, which utilizes hand-layup patches or full system replacements based on the severity of the wear. Hand-layup repairs allow technicians to apply structural reinforcements directly to damaged areas in the field, utilizing resin systems that cure quickly to return the pipe to service within hours. This capability is essential for maintaining production continuity during the high-demand windows often seen in the specialty paper sector.
Why is specialized fiberglass tank inspection a critical component of a mill's Risk-Based Inspection (RBI) program?
Standard visual inspections often miss the internal delamination or wicking that occurs within the core of an FRP laminate. Specialized fiberglass tank inspection services use both structural and chemical assessments to identify defects before they manifest as catastrophic failures. These inspections, recommended every two to five years, allow mill managers to move from a reactive maintenance posture to a predictive one. By identifying the early stages of resin degradation or mechanical stress, repairs can be budgeted and scheduled for planned outages, thereby avoiding the 83% higher costs associated with emergency maintenance.
How do custom plastic welding services support the integrity of high-purity and chemical feed systems?
In many parts of the mill, particularly in high-purity or secondary containment areas, thermoplastics like High-Density Polyethylene (HDPE) or Polypropylene are used due to their unique resistance profiles. Expert plastic welding is required to ensure these systems remain leak-proof at the joints. Plastech provides specialized field welding for fuel and chemical feed systems, creating seamless bonds that are as strong as the parent material. This precision is paramount in ensuring that corrosive additives do not penetrate the secondary containment or contaminate the finished product.
What role do high-performance protective coatings play in preserving floor and secondary containment infrastructure?
The floors and containment basins of a pulp mill are constantly subjected to chemical splashes, high moisture, and heavy equipment traffic. PlasTech provides chemical-resistant and slip-resistant floor coatings that protect the underlying concrete from acid-induced spalling. Without these barriers, corrosive liquids would penetrate the concrete, attacking the steel reinforcement and compromising the building's structural integrity. These coatings are a vital second line of defense in the mill’s overall asset preservation strategy.
What role do high-performance protective coatings play in preserving floor and secondary containment infrastructure?
The environment inside a pulp mill is lethal to modern computerized process controls due to high humidity and the presence of H2S and ClO2 gases. Plastech's Mechanical contracting teams specialize in the installation and maintenance of industrial HVAC systems, including Computer Room Air Conditioning (CRAC) units and Air Handling Units (AHUs). These systems do more than regulate temperature; they provide the filtration and positive pressurization necessary to exclude corrosive gases from control rooms and Motor Control Centers (MCCs). This precision climate control is a fundamental requirement for the reliability of the mill's automation systems.
How does ISO 9001 certification specifically translate to better maintenance outcomes for mill managers?
ISO 9001 certification, such as that held by PlasTech Services Inc., ensures that a contractor follows a rigorous, documented Quality Management System (QMS). For a mill manager, this means that every repair, from a simple patch to a full tank reline, is conducted following industry standards that prioritize precision, safety, and craftsmanship. This commitment to quality is reflected in customer feedback, noting that the "safety mindset and attention to detail" often result in repairs that are completed ahead of schedule without cutting corners.
