(one) No defect is permitted that is probably going to weaken the concluded cylinder appreciably. A fairly smooth and uniform surface finish is required. The shell part have to be a reasonably accurate cylinder.

(i) The remaining cylinders in Every single lot must be tension analyzed by the evidence tension, water-jacket or immediate expansion take a look at strategy as prescribed in CGA C-1. The least examination strain must be preserved for the specific timeframe as well as screening equipment have to be calibrated as prescribed in CGA C-1.

A physical take a look at have to be performed to find out yield energy, tensile strength, and elongation as follows:

(four) All cylinders have to be inspected through the magnetic particle or dye penetrant system to detect the presence of quenching cracks. Any cylinder discovered to have a quenching crack need to be rejected and will not be requalified.

Cylinders need to be produced employing machines and procedures enough to make certain that Just about every cylinder produced conforms to the requirements of the subpart. No fissure or other defects is permitted that is likely to weaken the completed cylinder appreciably. A fairly easy and uniform surface end is required. If not at first no cost from such defects, the surface area could possibly be machined or or else treated to eliminate these defects.

Reheat cure of turned down cylinders is authorized just one time. Subsequent thereto, cylinders should move all prescribed checks to generally be satisfactory.

(4) Figure out porosity of filling and tare weights; validate compliance of marking with prescribed needs; attain needed copies of metal shell studies; and furnish entire studies required by this specification read more to the person who has accomplished the manufacture of the cylinders and, upon ask for, towards the purchaser.

(iii) Once the size of the cylinder isn't going to permit securing straight specimens, the specimens may be taken in almost any spot or path and may be straightened or flattened chilly, by strain only, not by blows.

(ii) In utilizing the “extension under load” process, the full strain (or “extension below load”), corresponding to the stress at which the 0.2 per cent everlasting pressure happens might be decided with adequate accuracy by calculating the elastic extension on the gauge duration underneath suitable load and including thereto 0.

(1) By greatest appliances and techniques. No defect is acceptable that is probably going to weaken the finished container appreciably. A fairly sleek and uniform floor complete is needed.

(four) A take a look at cylinder or check ring require depict only among the heats in the furnace batch provided the other heats during the batch have Earlier been analyzed and possess handed the exams and that these kinds of checks do not depict a lot more than two hundred cylinders from Anybody warmth.

S = Mc/I (iii) To determine the utmost longitudinal tensile worry as a result of hydrostatic exam pressure, the following system must be employed:

Materials has to be determined by any acceptable method. Steel stamping of heat identifications might not be manufactured in any spot which is able to eventually become the side wall from the cylinder. Depth of stamping might not encroach upon the bare minimum prescribed wall thickness on the cylinder.
