Pharmaline is a unique,
smoothbore PTFE-Lined hose product, based on a patented PTFE
hose liner tube design. Pharmaline is designed to overcome
the primary disadvantage of currently available similar
products, namely POOR FLEXIBILITY.
Although excellent flexibility is often claimed for
comparable products, the truth is that they are all
considerably less flexible than Pharmaline, particularly in
large bore sizes.
For example, the force required to bend a length of 1" bore
Pharmaline hose to a 10" (250mm) Bend Radius in a U-shape is
77% less than that for its nearest rival product! - 1.8lb
(0.82kg) instead of 7.8lb (3.56kg). Pharmaline also has the
smallest minimum bend radius. |

An antistatic option is also available,
Pharmaline AS, using liner material in
accordance with the FDA requirement 21 CFR
178.3297.
Both Pharmaline GP and Pharmaline AS have been
tested and the PTFE liners comply with USP Class
VI, including the Elution (Cytotoxicity) test.

 |
|
|
|
The Silicone
Rubber material is in accordance with FDA
requirement CFR-177-2600.
Alternative colors of the silicone rubber cover
are also available, to special order. Clear,
transparent silicone is one alternative, which
is USP VI approved and permits inspection of the
inner braid condition.
Other colors are more expensive and are not USP
VI approved.

GP GRADES
Purpose
GP is the ‘General Purpose’ grade, for use in all
applications where fluids or gases are being
conveyed which do not generate a risk of static
charge development (see “AS”).Design & Approval
GP Grade has a virgin PTFE liner, manufactured
from hose grade PTFE which conforms to the requirements of
FDA 21 CFR 177.1550.
Both the PTFE liner tube and the platinum cured
silicone rubber cover have been tested and conform
to the requirements of USP Class VI. Additionally,
the PTFE liner tube meets the requirements of USP Class VI
at 121˚C (250˚F) |
 |
|
|
|
Pharmaline hose (but not Pharmalex Hose) in sizes
3/4” and above includes a Grade 304 SS wire
helically wound in the external convolutions, to
reinforce the hose against kinking.
EC - Electrical Continuity
(Also known as “Electrically Bonded”)
Electrical continuity requires that the hose assembly
supplied is electrically continuous, or conductive,
between metal end fittings at each end of the hose.
This can apply whether the hose is GP or AS grade.
The requirements for this are specified in the German
Document BRG 132 and EN ISO 8031:2009 Annex A,
when tested in accordance with EN ISO 8031:2009
Clause 5, which requires that the resistance between
end fittings shall be <102 ohms per assembly. For hose
assemblies which meet this requirement a Grade "M"
marking can be applied in accordance with EN ISO
8031:2009 Annex A if requested.
Pharmaline Hose Assemblies with crimped fittings are
all electrically continuous.
Pharmaline hose assemblies with Relink fittings are not
normally Electrically Continuous, but can be made EC
by a special Assembly Procedure RRF-SA-001/2.
Pharmalex hose assemblies are not Electrically
Continuous.
AS GRADES
Purpose
AS Grade is an
essential requirement in applications where
there is the risk of an electrostatic charge
buildup on the inside surface of the PTFE tube
which may then discharge through the tube wall.
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 nonpolar
organics which are being transferred at a medium
to high flow velocity.
All 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.
Design &
Approval
AS Grade hose 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. AS
Grade also conforms to the requirements of USP
Class VI, at 37˚C (99˚F), 70˚C (158˚F) and 121˚C
(250˚F).
Antistatic Hose
Assemblies
When "AS" (Antistatic) grade hose is specified,
then the hose or hose assembly supplied will be
tested in accordance with EN ISO 8031:2009
Clause 7 using electrodes specified in EN ISO
8031:2009 Clause 4.2.2.2 d) (and Clause 4.2.2.2
e if the hose has an antistatic cover) and meet
the Antistatic requirements
of EN ISO 8031:2009 Annex A. 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. For
hose assemblies which meet these requirements an
appropriate Grade "Ω" marking can be applied in
accordance with EN ISO 8031:2009 Annex A if
requested.
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. |
