FEP Plastic Tubing

A: They can transport low-concentration, small-particle media because their smooth surface is not easy to adhere to; however, high-concentration, large-particle media may wear the pipe wall. It is recommended to choose thickened types or match with wear-resistant outer layers, and shorten the inspection cycle.

A: Under normal use , the light transmittance can remain stable for a long time; if exposed to strong ultraviolet rays or temperatures exceeding 200℃ for a long time, slight yellowing may occur, affecting light transmission but not reducing corrosion resistance. It is recommended to choose a light-shielding protective cover for such scenarios.

A: No difference. Colors are only achieved by adding food-grade colorants to distinguish pipeline identification, and do not affect core properties such as chemical stability, temperature resistance and light transmittance.

A: Regular models can be used in environments with vacuum degree ≤-0.08MPa. If the vacuum degree is higher, thickened wall vacuum-specific models should be selected to avoid pipe wall collapse due to internal and external pressure differences; at the same time, ensure no impurities in the pipe to prevent scratching the inner wall during vacuuming.

A: If there are only minor surface scratches, gently polish with fine sandpaper , then apply FEP-specific repair agent . After curing, the surface integrity can be restored; if the scratch is deep or cracks appear, repair is not recommended, and the pipe must be replaced to avoid leakage.

A: Short-term outdoor use can withstand direct sunlight, wind and rain; for long-term exposure, it is recommended to install a sunshade protective cover, because ultraviolet rays may accelerate surface aging, which does not affect corrosion resistance but may reduce light transmittance and mechanical strength.
