Overview
This category refers to industrial valves or fittings featuring a Polytetrafluoroethylene (PTFE) lining within a metallic shell. Designed for extreme chemical resistance, these components utilize a steel structural liner to maintain pressure integrity while the fluoropolymer coating prevents corrosion from aggressive media.
Application
- Chemical Processing: Handling strong acids, alkalis, and solvents in reactors and pipelines.
- Petrochemical Industry: Used in transfer systems for corrosive crude derivatives and byproducts.
- Pharmaceutical Manufacturing: Ensuring purity in fluid transfer where contamination must be avoided.
Precautions
- Strictly avoid mechanical abrasion against the inner lining during installation or cleaning.
- Implement periodic inspections to detect delamination or wear caused by high-velocity flow.
- Replace units immediately upon signs of PTFE degradation to prevent catastrophic leakage.
