All Corroline+ hose assemblies are labeled with the following information:

• Manufacturer’s Name (Aflex Hose Ltd)
• Hose Size and Grade
• EN16643 and year of standard publication
• EN16643 Electrical Property Grade
• Max. Working Pressure and Test Pressure
• Working Temperature Range
• Unique Serial Number
• Month & Year of Manufacture
• Aflex Hose Telephone Number

This information is normally laser-etched on to a loose stainless steel ring mounted on the hose.

In some cases, at the discretion of Aflex Hose, the information may be etched on to a thin stainless steel plate which is clamped to the hose, or on to the end fitting ferrule at one end. This may be necessary for example, if the customer requires additional information which may not fit on to a Ring.

Customers may specify which labeling system they require, and may request additional information on the label.

Color Coding

*To special order, end fittings components can be made in non-standard grades of SS such as 1.4571, 1.4435, or other materials such as Hastelloy or Monel

How to Order

The quantity, hose size, grade, length and fittings must be specified in full.

Either by a full, written description. The hose grade can be specified by the code initials e.g. ‘Corroline+ AS, SG’ defines an antistatic PTFE lined hose which includes an outer Safegard sleeve.

The quantity, length and fittings can then be written in - e.g. “4 off x 1” bore Corroline+ AS, SG hose x 3.00 metres long. Both ends non-lined ANSI 150# S/S Flanges”.

or by Part Numbers, as defined in Part Numbers - e.g. 4 off Part No. 16-CLN+AS-SG-3.00m-12-12

Any special requirements relating to the hose construction, or information required on Tags, or Certificates, or special testing requirements, must be specified in full on the enquiry or purchase order.

Cleaning & Sterilising Systems - CIP, SIP and Autoclave

CIP & SIP PTFE liner tubes are chemically resistant to all CIP, SIP and Autoclave conditions. A primary consideration is whether the cleaning and purging cycle is likely to develop an electrostatic charge on the internal surface of the liner, in which case AS (Anti-Static) grade hose is required.

AS grade hose and Electrostatic charge generating systems are fully described in the hose liner section.

CIP systems using high electrical resistivity solvents like Toluene will require AS grade hose.

Another electrostatic generation problem arises when wet steam is passed through, or when the cleaning fluids or WFI are purged out of the line using nitrogen, compressed air or another gas, because droplets of liquid or water in the gas then generate a multi-phase condition until they are cleared out, which will generate a static charge, and so will require AS grade hose.

Autoclave

Corroline+ hose is able to withstand at least 100 x 30 minute autoclave cycles at relatively high autoclave temperatures (up to 135°C, 275°F). Consult Aflex Hose for more specific information.

PTFE Hose-Use with Alkali Metals, Halogens and certain Halogens
containing Chemicals

PTFE hose liners react chemically with Fluorine, Chlorine Trifluoride and molten Alkali Metals and so no hose grades are suitable for use with these chemicals.

When PTFE lined hose is used to carry Chlorine or Bromine, either as gasses or fluids, trace quantities can diffuse into and through the PTFE liner wall thickness. These will then combine with atmospheric moisture to corrode the SS braid or rubber cover outside the liner tube. It has been found that Corroflon SP, HB or KYB hose is best suited for these applications - Please consult the Corroflon brochure.

Depending upon the internal pressures and temperatures, some other gasses and fluids with a high halogen content may also be transmitted in trace quantities through the wall of the PTFE tube, including Hydrogen Fluoride, Hydrogen Chloride, Carbonyl Chloride (Phosgene), Carbon Tetrachloride and others. Please consult with Aflex Hose for a suitable hose grade recommendation.

Other “Penetrating” Fluids and Gases

Sulphur Trioxide, Methyl Methacrylate, Caprolactam and Glacial Acetic Acid are some other chemicals which do not react chemically with the PTFE, but which can be absorbed and transmitted in trace quantities through the PTFE liner tube wall - please consult Aflex Hose for the optimum solution with these chemicals.

Generally, however, as a hydrophobic (non-wetting) material, PTFE is very resistant to the absorption of chemicals. In some cases, PTFE has superior resistance to diffusion, for example to the diffusion of automotive fuels, in comparison with all other plastics and rubbers.

Gas/Fluid Cycling

There are some applications where fluids then gasses are passed through the hose, in a cyclic sequence.

This is normally associated with changes in temperature and/or pressure. For complex reasons these conditions are extremely damaging to the hose liner, whatever material it is made from.

For example, hoses are sometimes used to pass steam, water, steam etc into rubber moulding presses, in order to heat the mould, then rapidly cool it before reheating in the next cycle. Hoses of all types fail rapidly in such an application and PTFE lined hoses are no exception.

Please contact Aflex Hose for further information if these conditions apply.

Connecting Assemblies for Use in Applications

The lengths of hose assemblies and their configuration in use when connected into the application must always be in accordance with the Hose Configuration information at the end of this product literature.

When being connected for use in applications, the end fittings on hose assemblies must be connected to correct mating parts in the correct way, using the correct tools, spanners, clamps, nuts and bolts etc. The connections must be sufficiently tightened to ensure that the joint is leak free but not be over tightened as this can damage the sealing surfaces, especially with PTFE lined and flared end fittings.

In applications involving the transfer through the hose of expensive or dangerous fluids or gases, the hoses and connections must be pressure tested in situ before being put in to service. This should be done with some harmless media to 2.0 times times the maximum working pressure of the hose assembly, as stated in the product literature.

If in doubt please contact Aflex Hose for advice.

Special Applications

Aflex Hose PTFE lined hose products are not rated as suitable for use in the following, special applications:

• All Radioactive Applications involving high energy radiation, including Gamma radiation
  (degrades PTFE)
• All Medical Implantation Applications.
• All Aerospace Applications, except by special prior agreement, confirmed in writing.

Silicone-Free Application requirements

Some applications, particularly paint manufacturing plants, and other specialised applications require that hoses do not include any silicone containing materials in their manufacture, or sometimes that hoses are guaranteed to be 100% Silicone Free. Customers or Distributors must specifically identify and define any such requirements in writing on all enquiries/orders.

The Fourth Rule is that the hose must not be subjected to torque, either during connection, or as a result of the flexing cycle.

Torque (twist) in the hose can be applied during connection if the hose is accidentally twisted, or if the second end being connected is a screwed connection, and the hose is subjected to torque during final tightening.

In a flexing application, if any flexing cycle of the hose occurs in 3 dimensions instead of 2, then torque will also occur:

Example:

To calculate the length for a 2” bore size hose with flange end fittings, to be fitted in a 90° configuration with one leg 400mm long, the other 600mm long.

Length of Bent Section (yellow) = 1/4 x 2ΠR (334) = 1/4 x 2 x 3.142 x 334 = 525mm

Length of top, Straight Section, including the top end fitting length = 600 - 334 = 266mm

Length of bottom end fitting = 66mm

Total length of Hose Assembly = 525 + 266 + 66 = 857mm

Things to consider

1. A hose will normally take the longest radius available to it to go around a corner, not the MBR! Also - always remember to include the non-flexible end fitting lengths.
2. In dynamic applications, remember to always calculate the lengths for the most extended configuration during the flexing cycle, not the least extended.
3. If the configuration is simply too complex for calculation, then obtain a length of flexible tubing of some kind, mark on paper, or a wall, or floor, or both where the connection points will be relative to each other, scaled down if necessary, then manually run the flexible tubing between them with full radii round bends. Measure the extended length, then scale up if necessary to determine the approximate length of the hose.

If in doubt, consult Aflex Hose.
