Data sheet rubber hose 2 1/2 inch type 316

Data sheet rubber hose 2 1/2 inch type 316 iso#

Sizes above 2вЂќ bore are hand-wrapped, not extruded.Д®PDM has excellent chemical resistance, and the hose has a temperature range from -40ЛљC, -40ЛљF up to +150ЛљC, +302ЛљF. DesignДЄn SS braided hose has a black, antistatic EPDM external rubber cover extruded directly onto the braid to produce a super-smooth external surface finish. Also for hygienic applications, where the external cleanability of the hose is of prime importance and in applications where the hose is required to be Fire Proof, or to have an Antistatic cover. For hose assemblies which meet this requirement a Grade вЂњMвЂќ marking can be applied in accordance with EN 16643.ДЇor the most rugged applications where the hose may be subjected to rough treatment and severe external abrasion.

The requirements for this are specified in the German Document BRG 132 and EN 16643, when tested in accordance with EN ISO 8031, which requires that the resistance between end fittings shall be <102 ohms per assembly.

SPECIAL NOTE:Д®C - Electrical Continuity (Also known as вЂњElectrically BondedвЂќ) Same as for SS in Specifications & Properties, except the Burst Pressures and the Maximum Working Pressures are both reduced to 80% of the SS pressures listed.ДЄlso, the sizes range is restricted, from 1/2вЂќup to 2вЂќ bore only. This should only be used, however, in conjunction with a Monel or Hastelloy Helix Wire.ДЇull details about the applications should be given to Aflex Hose for evaluation and recommendations. Diffusion of trace quantities of such fluids or gases through the PTFE liner can lead to atmospherically wetted halogen chemicals attacking the braid material, in which case the Hastelloy Braid would be resistant up to 60ЛљC (140ЛљF) maximum. 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 вЂњО©вЂќ marking is applied inВ 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 вЂњASвЂќ (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).Д¬orroflon AS hose liner tube also conforms to USP Class VI at normal temperatures and at 121ЛљC (250ЛљF), 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 & ApprovalsД¬orroflon AS grade has an anti-static PTFE liner manufactured from FDA 21 CFR 177.1550 approved PTFE, and less than 2.5% of вЂњhigh purityвЂќ 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 вЂњWater for InjectionвЂќ) and non-polar organics which are being transferred at a medium to high flow velocity.ДЄll 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.ДЄ 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 neededД¬orroflon Sizes, Grades, Pressure Ratings & Weights Nominal Hose Bore SizeД®N16643 Hose Assembly Electrical Property GradesД¬orroflon 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.
