Steel-lined PE Storage Tank Technology and Characteristics:
Steel-lined plastic storage tanks are made from polyethylene (PE) and formed using the rotational molding process (heating and molding) for one-time integral shaping. The steel mesh is welded to the surface of the steel body, integrating the steel body, steel, mesh, and plastic into a single unit.
Structure: Steel-lined plastic products typically consist of the cylinder body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level opening flange. Horizontal steel-lined storage tanks usually also include standard steel supports. Steel-lined plastic products are generally designed and manufactured based on the specific on-site usage requirements of the customer.
Steel-lined plastic storage tanks feature excellent overall quality, high strength, seamless design, non-leakage, impact resistance, good flexibility, lightweight, long service life, resistance to acids and alkalis, resistance to organic solvents, compliance with hygiene standards, and a wide range of specifications and varieties. Particularly, their corrosion resistance, long service life, and diverse specifications and varieties offer significant advantages, making them the ideal choice for storing and transporting various types of chemical liquid and semi-solid substances.
Steel-lined PTFE Storage Tank Technology and Characteristics:
A steel-lined PTFE storage tank refers to selecting a suitable thickness of 3mm/4mm PTFE board based on the specific operational requirements of the customer, bonding the PTFE board to the inner surface of the steel body to achieve corrosion resistance. The specific steps include first sandblasting and cleaning the steel base of the equipment with a cleaning agent, followed by drying. Then, a special adhesive is evenly coated on the inner surface of the product, and an adhesive layer is also applied to the reverse side of the PTFE board. The PTFE board is then placed in position, with the adhesive-coated board first adhered, and then locally heated and rolled to expel air trapped between the layers for a tighter fit. After the composite panels are fully adhered, a professional slotting machine is used to create a "V" shaped slot at the junction of the panels. An imported high-temperature welding torch and Φ3.5mm PFA welding rods are used to weld the two panels together in the slot, ensuring no impurities, bubbles, or open joints. After the overall welding is completed, a pinhole tester is used to test for micro-pores at 15,000 volts and make repairs if necessary. Upon completion of the inspection, an imported slotting machine is used to flatten any protruding welds on the composite panels, followed by reinforcing them with 20mm wide welding strips to ensure a secure and bubble-free weld. The completed welding is then tested for pinholes at 30,000 volts to further confirm the welding integrity, and any impurities in the seams are cleaned out.
