• Forming and Welding: Metal sheets are cut, rolled, and formed into the required vessel shape (cylindrical, rectangular, conical bottoms). Welding processes (e.g., MIG, TIG, Submerged Arc Welding) are employed, often under stringent ASME Boiler and Pressure Vessel Code (BPVC) guidelines, to ensure structural integrity.
• Nozzle and Fitting Integration: All inlets, outlets, manways, and instrument connections are precisely fabricated and welded into position.
• Non-Destructive Testing (NDT): Welds are thoroughly inspected using methods like radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT), or liquid penetrant testing (PT) to detect any flaws.

2. Surface Preparation

• Abrasive Blasting: The internal surface of the tank is grit-blasted to a near-white metal finish (e.g., SSPC-SP 10 / NACE No. 2), removing rust, scale, and contaminants, creating an optimal anchor profile for rubber adhesion.
• Cleaning and Degreasing: Post-blasting, the surface is meticulously cleaned to remove all dust, oils, and residues, ensuring a pristine base for bonding.

3. Adhesive Application & Rubber Lining

• Primer and Adhesive Coats: Multiple layers of specialized primers and adhesives are applied to the prepared metal surface. These bonding agents are crucial for forming a strong, durable bond between the steel and the rubber.
• Rubber Sheet Application: Pre-calendered rubber sheets (typically 3-6mm thick, but can be thicker for heavy-duty applications) are cut to size and carefully applied by skilled technicians. Overlapping seams are critical and are meticulously rolled to eliminate air pockets and ensure a continuous, impervious barrier. Different rubber compounds are chosen based on the chemical resistance required, such as natural rubber (for abrasion), butyl (for acids/alkalies), EPDM (for ozone/weathering), or neoprene (for oil/chemicals).

4. Curing (Vulcanization)

• Autoclave or Atmospheric Curing: Depending on the rubber type and tank size, the lined tank undergoes a curing process. This can be done in a large autoclave (steam vulcanization) under controlled temperature and pressure, or by atmospheric curing (for specific compounds), which cross-links the rubber polymers, giving the lining its final mechanical properties and chemical resistance.

5. Final Inspection and Testing

• Spark Testing: A high-voltage spark test is performed across the entire rubber-lined surface to detect any pinholes, thin spots, or breaches in the lining that could compromise its protective capabilities.
• Adhesion Testing: Samples or designated areas might undergo adhesion tests to verify the bond strength between the rubber and the tank substrate.
• Visual Inspection: A final thorough visual inspection confirms the quality of the lining, seam integrity, and overall finish.
