Engineering and Technical Details of Sectional Tank Installation

 

  1. Materials and Construction
    • Panel Materials: Sectional tanks are commonly constructed from materials such as GRP (Glass Reinforced Plastic), FRP (Fiberglass Reinforced Plastic), stainless steel, or other composite materials. Each material offers specific advantages:
      • GRP/FRP: Lightweight, corrosion-resistant, and suitable for a wide range of liquids including water, chemicals, and wastewater. Panels are typically fabricated using a molding process, ensuring uniformity and durability.
      • Stainless Steel: Provides excellent mechanical strength, durability, and resistance to corrosion. Suitable for applications requiring high hygiene standards or exposure to aggressive chemicals.
    • Panel Design: Panels are engineered to withstand operational loads, environmental conditions (including wind and seismic forces), and temperature variations. Design considerations include:
      • Thickness: Panels are designed with varying thicknesses depending on tank size, fluid density, and external pressure requirements.
      • Reinforcement: Structural reinforcements such as ribs, stiffeners, or corrugations may be integrated into panel designs to enhance strength and stability.
  2. Assembly Techniques
    • Bolted Connections: Panels are typically connected using stainless steel bolts and nuts. Bolt holes are pre-drilled during manufacturing, ensuring precise alignment during assembly.
      • Sealing: High-quality gaskets or sealing materials (e.g., EPDM rubber) are placed between panel joints to ensure watertight seals. Sealing materials are selected based on chemical compatibility and temperature resistance.
    • Torque Specifications: Bolts are tightened to manufacturer-recommended torque values to achieve uniform compression of seals and prevent leakage. Proper torque control is critical to maintaining joint integrity and long-term performance.
  3. Structural Considerations
    • Foundation Design: Foundation requirements vary based on soil conditions, tank size, and local building codes. Common foundation types include concrete pads, ring beams, or compacted gravel bases.
    • Wind and Seismic Loads: Tanks are designed to withstand wind and seismic loads as per regional building codes and industry standards. Structural analysis considers factors such as tank height, wind exposure, and soil bearing capacity.
  4. Quality Control and Testing
    • Panel Inspection: Prior to installation, panels undergo visual inspection for defects, uniformity of construction, and adherence to manufacturing specifications.
    • Leak Testing: After assembly, tanks undergo hydrostatic pressure testing to verify integrity. Tanks are filled with water or another test fluid and pressurized to a specified level while monitoring for leaks at joints, seams, and fittings.
    • Material Testing: Raw materials used in panel construction undergo quality testing for mechanical properties, chemical resistance, and durability. This ensures compliance with industry standards and performance expectations.
  5. Documentation and Compliance
    • Technical Documentation: Comprehensive documentation includes assembly drawings, material certificates, test reports, and installation records. Documentation ensures traceability and compliance with regulatory requirements.
    • Regulatory Compliance: Installers adhere to local building codes, environmental regulations, and industry standards (e.g., ASTM, AWWA) governing the design, construction, and operation of sectional tanks.
  6. Environmental Considerations
    • UV Protection: For GRP/FRP tanks, UV-resistant coatings or additives may be applied to protect against degradation from sunlight exposure.
    • Chemical Resistance: Tank materials and coatings are selected based on their resistance to specific chemicals and environmental conditions encountered in the application area.

Conclusion

 

The installation of sectional tanks involves a blend of advanced engineering principles, meticulous assembly techniques, and rigorous quality control measures. By focusing on material selection, structural design, bolted connections, and compliance with regulatory standards, installers ensure sectional tanks deliver reliable performance, durability, and longevity for diverse industrial, municipal, and commercial applications


Engineering and Technical Details of Erection Process for Glass Fused to Steel Tanks

  1. Foundation Design and Preparation:

    • Soil Analysis: Before construction begins, soil analysis is conducted to assess bearing capacity and soil stability. This informs the design of the tank's foundation, ensuring it can support the weight of the tank and its contents.

    • Foundation Types: Depending on soil conditions and tank size, foundations may include concrete pads, ring beams, or compacted gravel bases. These foundations provide stable support and prevent settlement over time.

  2. Panel Handling and Installation:

    • Panel Specifications: GFS panels are typically made from low-carbon steel coated with a glass frit. Panels vary in thickness (typically 2mm to 6mm) depending on tank size and design requirements.

    • Handling Equipment: Panels are lifted into position using cranes or lifting equipment capable of handling heavy loads. Careful handling is crucial to prevent damage to the glass coating during transportation and installation.

  3. Bolted Connection and Sealing:

    • Bolt Specifications: Stainless steel bolts and nuts are used for assembly due to their corrosion resistance and strength. Bolt sizes and grades are selected based on engineering calculations to withstand operational loads and environmental conditions.

    • Sealing Materials: High-quality gaskets or sealing materials, such as EPDM (ethylene propylene diene monomer) rubber, are placed between panel joints to ensure a watertight seal. The selection of sealing materials considers chemical compatibility and temperature resistance.

    • Torque Control: Bolts are tightened to specific torque values recommended by the tank manufacturer. Torque control ensures uniform compression of gaskets, preventing under-tightening (which could lead to leaks) or over-tightening (which could damage the glass coating).

  4. Roof and Accessories Integration:

    • Roof Structure: For tanks with roof structures, roof panels or beams are installed and securely bolted to the top ring of the tank. Roof panels are sealed to prevent water ingress, and roof vents or hatches may be installed for ventilation and maintenance access.

    • Accessories: Inlet/outlet pipes, manways, level indicators, and other accessories are integrated into the tank design as specified by project requirements. Each accessory is securely mounted and sealed to maintain structural integrity and operational functionality.

  5. Quality Assurance and Testing:

    • Visual Inspection: Throughout the erection process, visual inspections are conducted to verify panel alignment, joint integrity, and the absence of defects in the glass coating or structural components.

    • Leak Testing: Hydrostatic pressure testing is performed after assembly to ensure the tank is leak-free. The tank is filled with water or another test liquid and pressurized to a specified level while monitoring for any signs of leakage from joints or seams.

  6. Documentation and Compliance:

    • Documentation: Comprehensive records are maintained throughout the erection process, including assembly procedures, inspection reports, bolt torque values, and test results. This documentation ensures compliance with industry standards and client specifications.

    • Safety and Training: Installation teams are trained in safety protocols and tank assembly procedures to prevent accidents and ensure efficient project execution. Client personnel may receive training on tank operation, maintenance, and safety practices.

Conclusion

The erection process of glass fused to steel bolted tanks integrates advanced engineering principles with meticulous construction practices to deliver durable, corrosion-resistant storage solutions. By emphasizing soil analysis, precise panel handling, proper bolted connections, and rigorous testing protocols, manufacturers and installers ensure GFS tanks meet performance expectations and provide reliable service in various industrial and municipal applications.
