PTFE lined pipes, pipe fittings
    1, the pressure: Standard ≤ 16Kgf/cm2 (1.6MPa)
     2, medium: all strong corrosive chemical media (except high-temperature
Molten alkali metals, elemental fluorine and chlorine trifluoride outside).
     3, temperature: -100 ℃ ~ 150 ℃
F4 lined pipe anti-corrosion pipe is all the most corrosion-resistant pipes, pipe fittings. Except molten alkali metals and elemental fluorine has almost three CFC can resist any kind. Any concentration of acid, alkali, salt, strong oxidizing agents, organic solvents, and all other strong corrosive chemical media corrosion, can be -190 degrees to 250 degrees to work, and maintain long-term anti-aging properties.
