-
Cylinders containing inert gas, non-toxic and non-flammable gases may be placed
in direct release position.
-
Cylinders containing toxic and flammable gases must be treated using
specialized equipment. The recovered gases may be used or treated safely and
must not be released directly into the environment.
b) Remove
valves from the cylinder head, prevent impact that can cause deformation or
damage to the cylinder’s valve or neck thread.
c)
Examine the tightness of the valves and safety parts (if any); reject failed
valves.
d) Clean
the inside of the cylinders (For acetylene cylinders containing porous mass,
the cleaning step is not required but the quality of the porous mass must be
checked according to the manufacturer's instructions or TCVN 6871:2007).
dd) Check
the inside of the cylinders with an endoscope to evaluate the metal
surface and welds (not applicable to soluble acetylene cylinders). In case of
any suspicion, request the establishment to adopt other appropriate measures.
e)
Evaluation: A cylinder is passed if its inside remains normal and there is not
any unusual sign. Reject cylinders according to point 4.8 of TCVN 6156:1996.

- Before
performing test with gas, the strength must be calculated according to actual
measurements of the cylinder
- Safety
measures in case of test with gas:
+ The gas
supply valve and sample pressure gauge on the gas inlet line must be placed
away from the cylinder location;
+ A
prohibition sign “No unauthorized entry to the test area” must be erected;
+ A safe
gas supply must be ensured.
Evaluation:
A cylinder is passed if the pressure does not decrease when maintained at the
test pressure, there is no leakage from the cylinder body or welds or there is
no deformation in excess of the prescribed limits.
dd) For
welded cylinders: carry out evaluation according to point 9.1 of TCVN
6292:2013.
e) For
seamless cylinders: carry out evaluation according to according to point C.4.3
of TCVN 6295:1997.

a) Water
jacket method: Enclose the water-filled cylinder in a jacket that is also
filled with water. The total and any permanent volumetric expansion of the
cylinder are measured as to the amount of water displaced by the expansion of
the cylinder when under pressure and after the pressure is released (carry out
evaluation according to C.5.2.1 of TCVN 6295:1997).
b)
Non-water jacket method: Measure the amount of water passed into the cylinder
as it is pressurized to test pressure and measure the amount of water expelled
from the cylinder to reduce the pressure to atmospheric pressure. First measure
the amount of water while increasing the water pressure in the cylinder to
determine the total expansion of the cylinder at test pressure, then measure
the amount of water expelled from the cylinder, subtract that amount of water
from the total expansion to determine the permanent volumetric expansion (carry
out evaluation according to C.5.2.2 of TCVN 6295:1997).
Evaluation:
according to point C.5.3 of TCVN 6295:1997.
For a
seamless cylinder (of a capacity between 12 and 55 l), rely on the increase in
volume or decrease in weight of the cylinder shell to reduce the working
pressure of the cylinder or reject it according to the provisions in point 4.10
of TCVN 6156:1996.
Note: The
volumetric expansion test on seamless cylinders shall be conducted together
with the strength test.
c) Remove
and clean the test medium; dry the inside of the cylinder.
d)
Install the tested valves on the cylinder.
6. Step
6: Tightness test
a) Test
medium: Air or inert gas.

c) For
seamless cylinders: Fill the cylinders with compressed air or inert gas to a
pressure of 50% to 60% of the maximum working pressure, hold this pressure for
01 minute.
d) Check
the tightness of the connectors, valve joints, etc. of the cylinders with soap
solution or in a specialized tank. Leaking cylinders must be treated and their
tightness must be re-tested.
Evaluation:
- For
welded cylinders: carry out evaluation according to point 9.2 of TCVN
6292:2013;
- For
seamless cylinders: carry out evaluation according to according to point C.6.3
of TCVN 6295:1997.
7. Step
7: Degassing and vacuuming
If a
cylinder is passed, proceed to completely degas the cylinder, dry its outside;
vacuum and fill the cylinder with shielding gas (if required).
8. Step
8: Checking tare weight of cylinders
a) Weigh
each cylinder and determine its tare weight (carry out evaluation according to
point 10.2 of TCVN 6292:2013). Check and compare it with the tare weight
stamped by the manufacturer on the cylinder;

contain sufficient information according to the form specified in the
Appendices to this inspection procedure.
b)
Approve the inspection record:
Mandatory
participants in the process of approving the inspection record include:

Note:
+ When a
cylinder batch is continuously numbered, the quantity of cylinders not included
in batches is small (since some cylinders were taken out by the manufacturer
for mechanical testing, destructive testing, etc.), write “DANH SÁCH CÁC CHAI
KHÔNG CÓ TRONG LÔ” (“LIST OF CYLINDERS NOT INCLUDED IN BATCHES”. When a
cylinder batch is not continuously numbered, write “DANH SÁCH LÔ CHAI” (“LIST
OF CYLINDER BATCHES”) and fully write numbers of cylinders in the batches.
+ If the
quantity of cylinders is small, write it in the record. An enclosed list of
cylinders is not required.
Note:
This list of cylinders must not be erased or modified and must bear a seal at
the upper left corner or seal on adjoining edges of pages.
