NEWS RELEASE
Luxfer Announces New Inspection and
Replacement Policy
for Scuba Cylinders Manufactured in Australia and U.S.
SYDNEY, Australia
(July 17, 2000)—Luxfer Gas Cylinders has announced a new inspection
and replacement policy for scuba cylinders manufactured at its
facilities in Australia and the United States. The primary purpose
for the new policy is to clarify inspection and testing procedures
for the two different aluminium alloys from which Luxfer scuba
cylinders have been manufactured. The text of the policy is as
follows:
Luxfer Scuba Cylinder
Inspection and Replacement Policy
Section I: Inspection and
Testing of Luxfer Scuba Cylinders
Manufactured from 6351 Aluminium Alloy
Luxfer scuba
cylinders were manufactured from 6351 aluminium alloy during the
following periods:
·
Australia: 1975 through
1990
·
United States: 1972
through mid-1988
·
England: 1967 through
1995
Luxfer requires that every Luxfer
6351-alloy all-aluminium scuba cylinder be visually inspected at
least every 2.5 years by a properly trained inspector. As part of
this inspection, Luxfer further requires that the cylinder neck be
tested with an eddy-current device such as Visual Plus, Visual Eddy
or equivalent non-destructive testing equipment. When properly used,
eddy-current devices contribute significantly to early detection of
difficult-to-observe sustained-load cracks in the necks of
6351-alloy cylinders. If the cylinder passes the inspection, the
inspector will document that fact. If the cylinder fails the
inspection, it must be removed from service immediately. Do not
use Luxfer 6351-alloy scuba cylinders that have not been both
visually inspected and eddy-current tested and then properly
documented.
This Luxfer-required visual and eddy-current
inspection is in addition to periodic requalifications (including
retesting and inspections) required or recommended by various
regulatory agencies around the world. The intervals between retests
and inspections vary from country to country.
In addition to the required inspection
and testing described above and in keeping with Australian and New
Zealand scuba industry standards, Luxfer recommends that all Luxfer
6351-alloy scuba cylinders be visually inspected at least once each
year by a properly trained inspector.
For cylinders in heavy use (for example, those filled five or more
times a week), Luxfer recommends visual inspection every four
months. For more information, refer to Luxfer’s Scuba Cylinder
Inspection Guide, which is available by calling Luxfer at
61-2-9830-0999 or by visiting the Luxfer web site at
www.luxfercylinders.com.
Section II:
Inspection and Testing of Luxfer Scuba Cylinders
Manufactured from 6061 Aluminium Alloy
Luxfer began manufacturing scuba
cylinders from a proprietary 6061 aluminium alloy in 1990 in
Australia, in mid-1988 in the United States and in 1995 in England.
The majority of Luxfer scuba cylinders currently in service are made
from this proprietary 6061 alloy, which Luxfer is still using.
Cylinders made from Luxfer’s proprietary
6061 alloy are not susceptible to sustained-load cracks. Therefore,
Luxfer does not deem it necessary to test these cylinders with
eddy-current devices such as Visual Plus and Visual Eddy. In fact,
field experience has shown that using such eddy-current devices with
Luxfer 6061-alloy cylinders can result in misleading
“false-positive” readings.
In keeping with
Australian and New Zealand
scuba
industry standards, Luxfer recommends annual visual inspection of
Luxfer 6061-alloy cylinders by a properly trained inspector. For
cylinders in heavy use (for example, those filled five or more times
a week), Luxfer recommends visual inspection every four months.
These recommended inspections are in addition to periodic
requalifications (including retesting and inspections) required or
recommended by various regulatory agencies around the world. The
intervals between retests and inspections vary from country to
country.

Section III: Luxfer Scuba
Cylinder Replacement Policy
This replacement policy applies only
to the original owner of a Luxfer scuba cylinder. If a properly
inspected Luxfer scuba cylinder is found to have either
sustained-load cracking (in the case of 6351-alloy cylinders) or a
manufacturing defect (i.e., any imperfection that fails to meet
product specifications at the time of manufacture), Luxfer will
honor the following replacement policy:
·
If the cylinder is 10
years old or less (based on the original hydrotest date), Luxfer
will replace the cylinder at no charge with a new 6061-alloy
cylinder. However, Luxfer will not replace cylinders that have been
damaged, abused or mistreated.
·
If the cylinder is more
than 10 years old, the original owner may purchase an equivalent
replacement 65, 75, 85 or 95 cu. ft. cylinder, 3500 psi fill
pressure, for A$137.50 or NZ$186 for cylinders manufactured in
Australia.
For DOT 80 cu. ft. cylinders, 3000 psi
fill pressure, manufactured in Australia or the United States, the
replacement prices are A$110 and NZ$152.
For 20 cu ft
cylinders, 3100 psi fill pressure, manufactured in Australia, the
replacement prices are A$110 and NZ$152.
Australian and
New Zealand prices include GST.
Luxfer cylinder
owners in Australia should contact Luxfer Gas Cylinders at
61-2-98300999 to obtain replacement cylinders.
Luxfer cylinder
owners in New Zealand should contact Luxfer’s New Zealand agent,
Tank Test Laboratories, at 64-9-2623628 to obtain replacement
cylinders.
