One cylinder taken at random out of each and every number of cylinders have to be hydrostatically analyzed to destruction.

(iii) For the objective of pressure measurement, the Original strain have to be established whilst the specimen is less than a anxiety of 12,000 psi as well as strain indicator looking through remaining set for the calculated corresponding pressure.

(1) Force, close to the same as but no below provider strain, should be applied to a person facet from the completed bottom about a region of at the very least one⁄16 of the overall place of The underside although not a lot less than three⁄four inch in diameter, such as the closure, for at least 1 minute, for the duration of which era the other aspect of the bottom exposed to stress has to be coated with drinking water and closely examined for indications of leakage. Except as offered in paragraph (n) of the portion, cylinders which can be leaking needs to be rejected.

Only open hearth, essential oxygen, or electrical furnace method metal of uniform quality is approved. The steel Examination should conform to the following:

(ii) Circumferential seams need to be made by welding or by brazing. Heads connected by brazing needs to have a driving healthy Using the shell Except if the shell is crimped, swedged, or curled more than the skirt or flange of The top and need to be thoroughly brazed until eventually full penetration through the brazing substance from the brazed joint is secured. Depth of brazing from conclude with the shell has to be at least four (4) periods the thickness of shell metallic.

(3) A plugged cylinder is 1 by which a long term closure in the bottom of check here the concluded cylinder has been effected by a plug.

(4) Decide porosity of filling and tare weights; confirm compliance of marking with prescribed demands; receive needed copies of metal shell stories; and furnish finish stories demanded by this specification to the one that has done the manufacture of your cylinders and, on ask for, to your purchaser.

(four) As a safety precaution, In case the manufacturer elects for making this examination ahead of the hydrostatic test, the company really should style and design the take a look at apparatus so that the pressure is placed on the smallest place practicable, round the place of closure, and in order to use the smallest probable quantity of air or gasoline.

Specimens taken through the circumferentially welded seam need to be Lower from 1 cylinder taken at random from each number of two hundred or much less cylinders after warmth therapy and will have to move satisfactorily the following checks:

(i) The remaining cylinders in Just about every large amount needs to be analyzed via the evidence force drinking water-jacket or direct expansion test method as prescribed in CGA C-one. The minimum amount exam stress should be maintained for the specific timeframe as well as tests products have to be calibrated as prescribed in CGA C-1.

A person set of a few impact check specimens (for each examination) need to be organized and analyzed for figuring out the effect Houses of your deposited weld metallic—

S = Mc/I (iii) To determine the most longitudinal tensile stress due to hydrostatic exam stress, the following formulation needs to be applied:

(two) Steel attachments to cylinders should have rounded or chamfered corners or needs to be secured in such a fashion as to forestall the likelihood of producing puncture or harm to other hazardous elements deals.

(ii) Taper threads to generally be of length not lower than as specified for American Common taper pipe threads.
