Markings need to be stamped plainly and forever with a lasting attachment or over a metal nameplate permanently secured to the container by usually means other than gentle solder.

(i) The remaining cylinders in Just about every ton has to be strain examined from the proof pressure, h2o-jacket or immediate expansion exam approach as prescribed in CGA C-one. The minimum amount check tension need to be preserved for the specific timeframe and also the screening devices have to be calibrated as prescribed in CGA C-one.

A physical test needs to be executed to find out generate toughness, tensile strength, and elongation as follows:

A person cylinder taken at random out of each and every large amount of two hundred or significantly less, must be subjected to the flattening test as follows:

Force-retaining components need to be identified by any appropriate strategy that does not compromise the integrity of the cylinder. Plates and billets for hotdrawn cylinders should be marked with the heat quantity.

(one) Every single cylinder need to be uniformly and appropriately warmth addressed just before check because of the relevant strategy shown in table 1 of appendix A to this aspect. Warmth therapy must be attained In fact forming and welding functions, other than that when brazed joints are utilised, warmth remedy must comply with any forming and welding functions, but may be performed right before, for the duration of or following the brazing operations (see paragraph (m) of this section for weld repairs).

(iii) For the objective of pressure measurement, the Original pressure need to be established whilst the specimen is underneath a worry of twelve,000 psi, and also the pressure indicator reading more info must be established on the calculated corresponding pressure.

Cylinders has to be produced employing products and processes satisfactory to make sure that Every single cylinder developed conforms to the necessities of the subpart.

The metal used in the development of your cylinder have to be as specified in table one of appendix A to this aspect. The cylinder maker will have to maintain a document of intentionally additional alloying components.

(iii) When dimension of cylinder isn't going to allow securing straight specimens, the specimens may very well be taken in any spot or direction and will be straightened or flattened cold, by pressure only, not by blows.

(iii) For the goal of strain measurement, the initial pressure have to be established even though the specimen is beneath a anxiety of twelve,000 psi and the strain indicator looking at getting set in the calculated corresponding pressure.

Ahead of the First cargo of any precise cylinder layout, cyclic pressurization exams must have already been performed on a minimum of 3 agent samples without the need of failure as follows:

(iii) The minimum test force needs to be preserved at the least thirty seconds and adequately lengthier to make sure total growth. Any inside tension used following heat-treatment and previous to the Formal exam may not exceed 90 p.c on the examination tension.
