The most usual way in which this can happen is when Chlorine, Bromine, Hydrogen Fluoride, Hydrogen Chloride or Phosgene are being transferred. Hastelloy Wire Braid is used instead of SS where severe chemical corrosion conditions exist around the outside of the hose. Note: When in service, at least one end fitting must be connected to earth, to permit dissipation of the static charge from the end fitting. For hose assemblies which meet these requirements an appropriate Grade “Ω” marking is applied in accordance with EN 16643. This requires, for an antistatic liner or antistatic cover, that the resistance between an appropriately placed foam electrode and a metallic end fitting will be between 103 to 108 ohms per assembly. When “AS” (Antistatic) grade hose is specified, then the hose or hose assembly supplied will be tested in accordance with EN ISO 8031 and meet the Antistatic requirements of EN 16643. (This has been confirmed by Extractables and Leachables Tests in accordance with BPSA recommendations).Ĭorroflon AS hose liner tube also conforms to USP Class VI at normal temperatures and at 121˚C (250˚F), see Quality Assurance & Certifications. The carbon is encapsulated by the PTFE, and in normal, non-abrasive applications will not come loose to contaminate any fluid passing through. Design & ApprovalsĬorroflon AS grade has an anti-static PTFE liner manufactured from FDA 21 CFR 177.1550 approved PTFE, and less than 2.5% of “high purity” Carbon Black material to FDA requirement 21 CFR 178.3297 and European Commission Directive 2007/19/EC. Media passing through which create such a risk are fluids which have a Conductance of less than 10-8 S/m (Siemens per Metre), or 104 pS/m such as fuels, solvents, freons, some WFI (ultra-pure “Water for Injection”) and non-polar organics which are being transferred at a medium to high flow velocity.Īll twin or multi phase media, and any non-mixing media, such as powder in air, or water droplets in steam, in gases or in oil, also colloidal fluids constitute a particular hazard for static charge generation, and always require grade AS.Ī typical example involves cleaning systems which create a twin phase mixture passing through the hose at high velocity, such as WFI water purged out with air or nitrogen. *Longer lengths may be available to special order if neededĬorroflon Sizes, Grades, Pressure Ratings & Weights Nominal Hose Bore SizeĮN16643 Hose Assembly Electrical Property GradesĬorroflon AS grade is an essential requirement in applications where there is the risk of an electrostatic charge build-up on the inside surface of the PTFE tube which may then discharge through the tube wall.
