PFA tube fittings are specialized connectors designed to be used with PFA pipes. They are made from fully fluorinated alkyloxy polymers and feature wide temperature tolerance, exceptional corrosion resistance, and high purity. Common types include compression-type, socket-type, and flange-type fittings, which are easy to install and provide strong sealing performance. They are ideal for applications in industries such as semiconductors, pharmaceuticals, and food processing, where cleanliness and corrosion resistance are critical.

FAQ

Q: 1.How is the purity of PFA pipe fittings guaranteed? Are they suitable for the semiconductor industry?

A: The production process is carried out in a Class 100 clean room, with metal ion content <1ppm and particle contamination <0.5μm, meeting SEMI F57 standards, fully suitable for scenarios with strict purity requirements such as semiconductor wafer manufacturing.

Q: 2.How to avoid leakage when installing PFA pipe fittings?

A: The pipe cut must be flat and burr-free ;
Ferrule fittings must be tightened to standard torque;
Control temperature and pressure during hot-melt welding to avoid pipe diameter reduction or cold welding due to over-welding.

Q: 3.Can PFA pipe fittings be directly connected to pipes of other materials such as stainless steel or PVC?

A: Direct connection is not recommended, as differences in thermal expansion coefficients of different materials may cause leakage. PFA adapters (such as PFA-stainless steel flange adapters) are required for transition, and PTFE/PFA gaskets should be used to buffer thermal expansion and contraction stress.

Q: 4.What certifications or standards should be confirmed when purchasing PFA pipe fittings?

A: It is necessary to confirm: ① Material purity report; ② Pressure and temperature resistance test reports; ③ Industry certifications.

Q: 5.What are the special requirements for food-grade PFA pipe fittings?

A: They must comply with FDA 21CFR177.1550 certification to ensure no harmful substances migrate when in contact with food; surface roughness Ra≤0.8μm, easy to clean without dead corners, and resistant to high-temperature steam sterilization to avoid microbial growth.
