(one) No defect is permitted that is probably going to weaken the finished cylinder appreciably. A fairly clean and uniform surface area finish is needed. The shell portion should be a fairly genuine cylinder.
(2) Verify compliance of cylinder shells with all shell specifications; inspect inside prior to closing in both finishes; validate warmth treatment method as suitable; receive all samples for all exams and for Examine analyses; witness all tests; validate threads by gauge; report volumetric capacity and bare minimum thickness of wall mentioned.
(1) Each individual tension specimen have to have a gauge length of two inches having a width not exceeding one particular and 1-fifty percent inches. Except for the grip finishes, the specimen will not be flattened. The grip finishes could be flattened to within just 1 inch of each and every stop in the lessened section.
(two) A plugged cylinder is one where a long lasting closure in the bottom of the finished cylinder has long been effected by a plug.
A root bend examination specimen need to be removed from the cylinder or welded examination plate which was employed for the tensile exam specified in paragraph (l)(1) of the section. The specimen should be taken from over the circumferential seam and needs to be ready and examined in conformance with and ought to meet the necessities of CGA C-three.
(1) Force, roughly similar to although not lower than assistance pressure, has to be placed on 1 aspect of your finished bottom around an area of at the least one⁄16 of the whole space of the bottom but not fewer than 3⁄4 inch in diameter, such as the closure, for a minimum of 1 minute, all through which time another aspect of the bottom subjected to strain has to be included with h2o and closely examined for indications of leakage.
(iii) The minimal exam stress need to be maintained at least 30 seconds and adequately longer to be sure complete growth. Any interior pressure utilized immediately after warmth-remedy and previous to the Formal check might not exceed ninety percent on the check force.
(ii) In using the “extension under load” process, the whole strain (or “extension more info underneath load”) akin to the tension at which the 0.two % long term pressure occurs may very well be decided with sufficient precision by calculating the elastic extension in the gauge duration beneath appropriate load and introducing thereto 0.
(iii) The bare minimum exam stress have to be maintained at the very least thirty seconds and adequately for a longer time to guarantee complete growth. Any inside tension applied right after heat-procedure and previous to the Formal exam may not exceed 90 % with the exam pressure.
(iii) The minimum take a look at tension has to be managed at least 30 seconds and adequately extended to be sure total expansion. Any inside strain utilized just after warmth-treatment method and before the official check may not exceed 90 % on the test stress.
(iii) When size of cylinder isn't going to allow securing straight specimens, the specimens may be taken in almost any spot or path and could be straightened or flattened cold, by tension only, not by blows.
Each individual cylinder, before insulating and jacketing, should effectively stand up to a stress check as follows:
(b) Each individual these twenty five,000 containers or much less, successively made every day, shall represent a great deal and In the event the examination container shall are unsuccessful, the ton shall be rejected or ten supplemental containers can be picked at random and subjected towards the test under which failure happened.
(ii) The filling materials should be uniform in top quality and free of voids, except that a perfectly drilled into your filling product beneath the valve is approved In case the properly is full of a material of such type which the capabilities on the filling materials aren't impaired;
