TIPS FOR YOU - "CYLINDER USED"
 
SUGGESTED PROCEDURES FOR MAINTENACE OF CYLINDERSIN SERVICE
GET EXTRA LIFE FROM YOUR HIGH PRESSURE GAS CYLINDERS
High Pressure Gas Cylinders whether obtained indigenously or imported are manufactured to high standards of quantity conforming to specifications accepted by the statutory authority, tested and certified by an independent inspecting agency.
 
No manufacturer can take any responsibility for the subsequent life of the cylinder during course of its filling, handling, transport, use etc. Hence it is evident that the life of the cylinder is entirely in the hands of the Filler & User alike.
 
If properly taken care of, a cylinder can give any length of service and thus result in greater profits.
 
For your benefit, herein listed are some TIPS for you as well as the end user of HIGH PRESSURE GAS CYLINDERS with the above objective in view. You will do well to educate not only persons engaged in the filling of cylinders under your own control but also your valued customers to follow the TIPS, thereby enhancing the life of your valuable asset viz. cylinders.
 
 
1. TIPS FOR YOU - "THE FILLER"
   
1.1
Gas cylinders should be received and off-loaded by properly trained persons only at the designated place marked " EMPTY CYLINDERS " or " MT " on the filling shed.
 
   
1.2
No cylinder should be allowed to be removed for filling unless the same has been examined and passed as fit by a competent person appointed for the purpose.
 
 
1.3
Customer's cylinders should be sorted out and not passed on for filling unless their History - Cards are available to ascertain the type of gas which was contained therein and results of the last hydrostatic pressure test are known.
 
 
1.4
All cylinders should be examined for their complete marking at the neck end to ascertain inter-alia the specifications, Chemical symbol of the Gas service, last date of hydrostatic pressure test, and symbol of the test station. If due for test, the cylinder should be segregated. All observations should be recorded in the history card/data card of the cylinder.
 
 
1.5
Cylinders which are badly dented, corroded or bearing burn marks should not be accepted for filling.
 
 
1.6 OPEN SPINDLE
 
Pressure is released
 
Cylinders with some residual pressure therein are considered to be positively acceptable.
 
Pressure is not coming out
 
Flush cylinder with the gas to get better purity. In case of any doubt, examine the cylinder internally.
 
Check threads of the valve outlet as well as spindle. Valve and spindle with defective threads should be replaced.
 
Inspect the cylinder for any outside defect, such as burnt marks, dent, bulge, cut, gouge, corrosion, etc. which are liable to weaken the cylinder and render it unfit for further use.
 
Before attaching to manifold conduct hammer test and if a clear ringing sound is heard, cylinders are good for filling. If dull, unclear sound is heard, check for weight loss, conduct internal inspection before filling the cylinder.
   
   
1.7 PRECAUTIONS WHILE FILLING
 
Cylinders should be stored on the filling platform free of water, dirt or any other combustible material. Grease or oily matter is especially injurious in case of oxygen cylinders as it may lead to explosion.
 
"No smoking " signs should be conspicuously displayed, forbidding induction of matches or lighters in the plant area.
   
   
1.8 QUALITY OF GAS
 
Compressed Gas must be as dry as possible and in not instance shall the aqueous phase separate when a liquified gas is cooled to 0o C. Presence of moisture in gas will accelerate stress corrosion. The moisture shall be less than 0.02 g/M 3 of gas at normal temperature and pressure.
 
Compressed gas should be free from impurities which are likely to corrode the metal of the cylinder or form an explosive substance with it or cause the gases to decompose or explode.
   
 
Before filling any cylinder with gases such as Carbon Monoxide, Coal Gas, Hydrogen or Methane, the gas should be made free of hydrogen sulphide or other sulphurous impurities as far as practicable.
   
  Once filled label appropriately.
   
 
2. RECORD
   
2.1 Filling station must maintain the following record in respect of each cylinder examined and tested filling :
   
  Name of the manufacturer and owner;
  Cylinder Serial Number / Rotation Number if different;
  Specification to which the cylinder conforms:
  Date of original hydrostatic stretch test;
  Test reports and certificates furnished by the manufacturer, if available;
  Test Pressure;
  Maximum working pressure;
  Water capacity;
  Date of the last hydrostatic stretch test and name of the testing station;
  Tare weight of the cylinder;
 
Variation, if any, in the tare marked on the cylinder and actual tare at the time of hydrostatic stretch test;
  Name of gas;
  Remarks;
 
   
2.2
Permission obtained from the statutory authority permitting the use of cylinder shall be preserved till the cylinder is condemned.
 
3. TIPS FOR YOU - " CYLINDER USERS "
   
3.1
Gas cylinders should be handled by properly instructed and trained persons only.
 
   
3.2
Take adequate care in handling cylinders so that these are not dropped or struck against each other violently. Cylinders shall be adequately supported to prevent falling during use. In horizontal position the cylinder shall be secured so that they cannot roll. Trolleys and cradles shall be used while moving them.
 
 
3.3
Always keep the valve shut after use. Maintain positive pressure in the cylinder. This will help in preventing moisture condensation due to climatic variations. Any moisture in the cylinder will accumulate with repeated fillings and as such accelerate corossion.
 
 
3.4
Do not repair, repaint or alter the colour of the cylinder.
 
 
3.5 Do not tamper with the markings stamped on the cylinder or the valve.
 
 
3.6
Do not place cylinders where they might become part of an electric circuit. Where cylinders are used near or in conjunction with electric welding, precaution should be taken against accidental grounding of compressed gas cylinders and allowing them to be burnt by electric welding etc.
   
   
3.7 Do not use the cylinder as a roller or as a packing support.
   
   
3.8 Ensure that protective valve guards / caps are there on the cylinders when not in use.
   
   
3.9 Store Cylinders under cover protected against extreme weather conditions.
   
   
3.10 Store the cylinder in well ventilated areas with clear indications as to the exits. Exits should be kept free from obstruction.
   
   
3.11 Store cylinder vertically as far as possible. In case the cylinders are stored horizontally, care should be exercised to prevent them from rolling over, heavier one at the bottom and the lighter ones at the top.
   
   
3.12 Keep empty cylinders separately from filled ones with distinctive markings, such as ` MT ' or ` EMPTY '.
   
   
3.13
Do not transport cylinders by crane or derrick. Lifting magnets, slings of rope or chain, or any other device in which the cylinders themselves form a part of the carrier, shall never be used for hoisting cylinders. Instead, when crane is used, a platform, cage or cradle shall be provided which will protect the cylinders from damage by slamming against obstructions and will keep them from falling out. The preferred construction is to build one which will take one or more cylinders.
   
   
3.14 Cylinder shall not be :
 
Lifted with an electromagnet
Kept near elevator, gangway or in a location where heavy moving object can fall on it;
Left near a source of heart like furnace, flame or naked light or hot slag;
Kept close to welding or cutting work so that spark may not fall on it;
Used as rollers, supports or for any purpose other than storing gas;
Kept in contact with an electric wire or fitting so that it may become path of an electric circuit;
Kept near acid or corrosive substances;
Lifted by its caps / protective guard;
Dragged or slid on floor and rolled over oily or greasy floor. A suitable hand cart should be used;
   
   
3.15 Oxygen cylinders, particularly their valves, shall be kept away from oily hands, gloves or rags.
   
   
3.16 Never use cylinder without ascertaining the gas it contains.
   
   
3.17
Do not force the connections which do not fit. It is important to make sure that the threads on regulator fitted to cylinder valve connections are properly matched. No jointing compound shall be used.
   
   
3.18 Do test for leakage of connections by soap water. Testing with a naked flame shall never be done.
   
   
3.19 Open Valves Slowly
  Do not open the valve of a full cylinder rapidly.
   
   
3.20
Do not use a worn out spindle key for opening or closing cylinder valve as it may damage the square head of the spindle. Extra leverage shall not be used on the cylinder spindle key for operation.
   
   
3.21 Do not use a worn out spanner for loosening or tightening the gland of the cylinder valve.
