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 (heated spinning) in one piece. The steel mesh is welded to the surface of the steel body, integrating the steel surface, steel, mesh, and plastic into a single composite structure.
Structure: Steel-lined plastic products typically consist of the body, flat bottom, top cover, manhole, inlet flange, outlet flange, and liquid level hole flange. Horizontal steel-lined storage tanks usually also include standard steel supports. Steel-lined plastic products are generally designed and manufactured based on the user's on-site application requirements.
Steel-lined plastic storage tanks feature excellent overall integrity, high strength, seamless design, no leakage, shock resistance, good flexibility, lightweight, long service life, resistance to acids and alkalis, resistance to organic solvents, compliance with hygiene standards, and a wide variety of specifications and types. Particularly, their corrosion resistance, long lifespan, and wide range of specifications and types offer significant advantages, making them the ideal product for storing and transporting various types of chemical liquid and semi-solids.
Steel-lined PTFE Tank Technology and Characteristics:
The PTFE-lining steel storage tank refers to selecting the appropriate thickness of 3mm/4mm PTFE boards based on the customer's specific operational conditions and requirements. The PTFE boards are bonded 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, followed by drying. Then, a special adhesive is uniformly 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, and the adhesive-coated PTFE board is first attached. Local heating and rolling are then employed to expel air trapped between the layers, ensuring a closer fit of the panels. After the composite panels are fully adhered, a professional slotting machine is used to create "V" shaped slots at the joint between the panels. An imported high-temperature welding torch is used with Φ3.5mm PFA welding rods, welding the two panels together in the slot. It is required that no impurities, bubbles, or leaks occur. After the overall welding is completed, a pinhole tester is used to test for microholes with a 15,000-volt voltage, and any repairs are made. After inspection, an imported groove planer is used to flatten the protruding welding rods on the composite panel, and a 20mm-wide welding strip is then used to reinforce the original welding rods, ensuring a firm and bubble-free weld. The completed welds are tested for pinholes with a 30,000-volt voltage to further confirm the welding quality. Any impurities in the gaps are then cleaned thoroughly.
