Raven Tanks, recognized leaders in tank design, installation, repairs, and maintenance across Australia and the Pacific, bring forth a symphony of expertise to ensure the production of tank liners that surpass industry standards. In this guide, unravel the art and science behind the manufacturing process of Raven Tank Liners, from material selection to quality control, and discover the unparalleled durability and effectiveness they bring to your water storage solutions. 


1: Mastering Material Selection for Raven Tank Liners 

The foundation of Raven Tank Liners lies in the careful selection of superior materials. Crafted from advanced thermoplastics such as polyvinyl chloride (PVC), high-density polyethylene (HDPE), reinforced polyethylene (RPE), or polypropylene (PP), Raven Tank Liners embody chemical resistance, flexibility, and durability: 

  • PVC: Offering flexibility and cost-effectiveness, ideal for applications like potable water storage, yet mindful of high-temperature environments. 
  • HDPE: Elevating chemical resistance and stress-crack resistance, perfect for chemical containment or safeguarding against groundwater infiltration. 
  • RPE: Infused with woven fabric reinforcement for enhanced strength, catering to challenging environments with resilience against high temperatures and heavy loads. 
  • PP: Tailored for specialized applications, excelling in chemical containment with remarkable resistance, though characterized by rigidity that may influence certain tank designs. 


Choosing the right material forms the cornerstone of the manufacturing process, ensuring Raven Tank Liners deliver uncompromised quality tailored to specific applications. 


2: The Symphony of Production Techniques 

Once the ideal material is chosen, the production process takes center stage. While techniques may vary based on the selected material, the common methods include extrusion, calendaring, and lamination: 

  • Extrusion: Melted plastic material is forced through a die to create a continuous profile or sheet. This method is predominantly used for producing HDPE, RPE, or PP tank liners. 
  • Calendaring: Raw material undergoes heating and pressing through rollers, achieving the desired thickness and consistency, primarily employed in PVC liner production. 
  • Lamination: Bonding layers of thermoplastic materials, sometimes with reinforcement materials like woven fabric, produces a composite sheet with enhanced properties. This technique may be used for manufacturing RPE liners or specialized combinations. 


Each technique contributes to the uniformity, strength, and consistency of Raven Tank Liners, maintaining a high standard tailored to specific applications. 


3: Harmony in Quality Control Measures 

Throughout production, rigorous quality control measures are in place to ensure Raven Tank Liners meet stringent standards of strength, durability, and chemical resistance: 

  • On-Site Inspections: In-process and pre-shipment inspections assess appearance, thickness, dimensions, and other physical properties, detecting potential defects early in production. 
  • Material Testing: Before production, raw materials undergo strict quality testing, ensuring performance properties align with chemical resistance, flexibility, and weather resistance for the intended application. 
  • Seam Integrity Testing: Particularly important for tank liners produced in sections and seamed together on-site, quality control measures like spark testing or air pressure testing ensure seam strength and watertightness. 


These meticulous quality control measures guarantee the integrity and reliability of Raven Tank Liners. 


4: Tailoring Excellence to Client Requirements 

To achieve optimum functionality and fit, Raven Tank Liners are often customized to individual client requirements, involving: 

  • Liner Size and Shape Tailoring: Precise measurements and specifications result in tank liners of various sizes, shapes, and designs, accommodating diverse applications. 
  • Incorporation of Custom Features: Liners may include custom features such as access hatches, pipe penetrations, or flanges, adapting to the unique conditions of the storage system. 
  • Selection of Material Properties: Customization extends to choosing specific materials or composites designed to withstand the unique challenges posed by stored contents or the tank environmentEN Tanks, drawing from extensive experience in designing and installing tank liners, collaborates closely with clients, developing custom solutions tailored to unique water storage system requirements.
