Steel-lined PE Storage Tank Technology and Characteristics:
Steel-lined plastic storage tanks are made from polyethylene (PE) and are formed through a rotational molding process (heating and molding) in one piece. Steel mesh is welded onto the surface of the steel body, integrating the steel surface, steel, mesh, and plastic into a single unit.
Structure: Steel-lined plastic products typically consist of the tank 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. These steel-lined plastic products are generally designed and manufactured according to the specific on-site usage requirements of the customer.
Steel-lined plastic storage tanks feature excellent overall integrity, high strength, seamless design, non-leakage, impact resistance, good flexibility, lightweight, long service life, resistance to acids and alkalis, tolerance to organic solvents, compliance with sanitation standards, and a wide variety of specifications. Particularly, their superior corrosion resistance, long lifespan, and diverse range of specifications provide a significant advantage, making them an ideal product for storing and transporting various types of chemical liquid and semi-solids.
Steel Lined PTFE Storage Tank Technology and Characteristics:
The steel-lined PTFE storage tank refers to a tank that, based on the specific operational requirements of the customer, selects an appropriate thickness of PTFE board (3mm/4mm) and adheres it to the inner surface of the steel body to achieve corrosion resistance. The specific steps include first sandblasting and cleaning the steel base with a detergent, 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 back of the PTFE board. The PTFE board is then affixed in the correct position. After applying the adhesive, the board is placed, and local heating and rolling are performed to expel air trapped between the layers, ensuring a tighter fit. Once all composite panels are bonded, a professional cutting machine is used to create a "V" shaped slot at the junction of the panels. An imported high-temperature welding torch with Φ3.5mm PFA welding rods is used to weld the two panels together in the slot, ensuring no impurities, bubbles, or gaps. After the overall welding is complete, a pinhole tester is used to test with 15,000 volts to check for any microholes and make necessary repairs. Upon completion of the inspection, an imported sawing machine is used to flatten any protruding welding rods on the composite panels. A 20mm wide welding strip is then applied over the original welding rods to reinforce the joint, ensuring a secure and bubble-free weld. The welding is then tested again with 30,000 volts to confirm the welding integrity. Any impurities in the seams are also cleaned.
