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

(iv) On a plate attached to the very best on the cylinder or long-lasting section thereof; sufficient House has to be remaining within the plate to offer for stamping a minimum of six retest dates; the plate have to be not less than 1⁄sixteen-inch thick and must be connected by welding in a temperature of one,one hundred °F, through all edges of your plate.

(i) Assuming the cylinder should be to be supported horizontally at its two ends only and to be uniformly loaded around its overall size consisting of the burden per device of size with the straight cylindrical part full of h2o and compressed to the desired test force; the sum of two instances the utmost tensile anxiety in the bottom fibers because of bending, as well as that in the exact same fibers (longitudinal worry), as a result of hydrostatic exam tension may not exceed eighty per cent on the minimum amount yield strength in the steel at such highest strain. Wall thickness must be amplified when needed to meet the prerequisite.

Only open up hearth, standard oxygen, or electric furnace method steel of uniform excellent is authorized. The steel Investigation should conform to the following:

A root bend check specimen have to be faraway from the cylinder or welded exam plate which was employed for the tensile check laid out in paragraph (l)(1) of this part. The specimen has to be taken from over the circumferential seam and have to be prepared and examined in conformance with and will have to fulfill the necessities of CGA C-three.

(3) Each and every check cylinder have to stand up to flattening to 9 instances the wall thickness with no cracking. In the event the alternate bend exam is utilised, the take a look at specimens have to remain uncracked when bent inward around a mandrel within the path of curvature in the cylinder wall until eventually the inside edges are at a length aside not greater than the diameter in the mandrel.

(iv) Permanent volumetric enlargement may not exceed ten % of the overall volumetric growth at check strain.

(1) Welding or brazing is licensed with the attachment of neckrings and footrings that are non-strain parts, and only on the tops and bottoms of cylinders using a company tension of 500 psig or much less.

1 container taken at random outside of two hundred or considerably less need to be hydrostatically tested to destruction. Rupture pressure should be incorporated as Component of the inspector's report.

(one) Every single cylinder needs to be heated and held at the proper temperature for a minimum of a single hour per inch of thickness according to the most thickness of your cylinder and after that quenched in an acceptable liquid medium having a cooling rate not in surplus of eighty % of h2o.

Cylinders needs to be made applying products and processes satisfactory making sure that each cylinder developed conforms to the requirements of the subpart. No defect is permitted that is probably going to weaken the concluded cylinder appreciably.

(2) A maker of a packaging subject matter to the necessities of this aspect is mainly accountable for compliance with the requirements of this aspect. Nonetheless, any person who performs a perform prescribed On this aspect shall accomplish that function in check here accordance with this component.

(ii) In utilizing the “extension below load” method, the full strain (or “extension less than load”) corresponding to the strain at which the 0.two % long term strain happens could be identified with sufficient accuracy by calculating the elastic extension with the gauge duration beneath suitable load and including thereto 0.

(iii) The bare minimum check strain have to be taken care of a minimum of 30 seconds and sufficiently for a longer time to make certain total growth. Any interior stress utilized just after warmth-remedy and ahead of the Formal test may not exceed ninety per cent of your test strain.
