Pipe Fitting Steel Elbow Lining Flupropolymer PTFE, PFA Lined Elbow or Fvdf Lined Elbow introduction: The Lined Elbow is the steel elbow lined with a layer of PTFE or PFA. The main purpose is to improve the corrosion resistance of the elbow, pipeline or valve, such as for transporting acid and base liquid, or improve its temperature and aging resistance. The flow of the medium in the main Lined Pipeline and the branch Lined Pipes can be clearly seen to ensure its production safety. Because the inner Fluoropolymer Lining that is made of fluoroplastics PTFE (F4), PFA and FEP (F46) which are high corrosion resistance and anti-calculation type materials. This lined elbow is an elbow model commonly used in the chemical and petroleum industries.…
