Steel-lined F4 anti-corrosion tank Steel-lined F4 storage tank Steel-lined PTFE chemical storage tank is a device that can be used in various modern industries. The PTFE lining material is known as the "Plastic King." Since its introduction to the market, it has played an indispensable role in the anti-corrosion industry due to its inherent advantages. Wuxi Hongfu's products in this category have gained recognition and support from the industry and customers, thanks to their mature production processes and stable product quality. Below, I will introduce

PTFE storage tank medium working temperature: -100°C to 250°C
PTFE storage tank medium working pressure: positive pressure 0.6Mpa to 2.5Mpa, negative pressure 70Kpa at room temperature.
It resists corrosion from aqua regia and can operate long-term at temperatures between 230°C and 250°C.

Steel-lined F4 anti-corrosion tank Steel-lined F4 storage tank Steel-lined PTFE chemical storage tank production process:

1. Form the tank body according to the drawings provided by the customer/designer;
2. After the tank body is formed, perform sandblasting and rust removal on the inner surface of the storage tank;
3. Sodium treatment of PTFE sheets;
4. Apply adhesive: Apply adhesive to both the PTFE sheet and the inner surface of the storage tank at least twice, ensuring even and complete coverage;
5. PTFE sheet application: Heat the PTFE sheet and use specialized tools to manually press and smoothly cover the equipment surface. This process may seem simple, but it is physically demanding. Uneven force application may require reapplication of the PTFE sheet, and in severe cases, the entire sheet may be scrapped.
6. Trim the joints between two PTFE sheets into a V-shaped groove to facilitate the next welding process;
7. Weld the groove using PFA round strips, then level the welded strips with the PTFE sheet, followed by welding with wide PFA strips;
8. Conduct a comprehensive inspection of the equipment using a 15kV spark tester.
