(one) Cylinder shells should be created with the backward extrusion system and possess a cleanliness amount sufficient to make sure suitable inspection. No fissure or other defect is acceptable that is probably going to weaken the concluded cylinder underneath the look strength demands.

Content should be discovered by any appropriate system except that plates and billets For warm-drawn cylinders should be marked with the heat number.

A root bend test specimen have to be cut from the cylinder or welded check plate, utilized for the tensile take a look at specified in paragraph (n)(1) of the area. Specimens should be geared up and tested in accordance with and should satisfy the necessities of CGA Pamphlet C-three.

(i) The remaining cylinders inside the large amount have to be analyzed from the proof stress, h2o-jacket, or direct expansion examination system as prescribed in CGA C-1. The least exam tension have to be taken care of for the precise timeframe and also the testing devices should be calibrated as prescribed in CGA C-1.

The least wall thickness need to be these types of the wall tension at the minimal specified take a look at force may not exceed 67 % from the minimum tensile strength of the metal as determined within the physical and burst assessments demanded and will not be about 70,000 p.

(one) Tension, somewhere around similar to although not less than assistance tension, has to be applied to a single side from the concluded base around a location of not less than one⁄16 of the overall spot of The underside but not under three⁄four inch in diameter, including the closure, for a minimum of a person moment, throughout which era one other side of the bottom exposed to pressure need to be protected with water and carefully examined for indications of leakage.

(four) Establish porosity of filling and tare weights; validate compliance of marking with prescribed specifications; receive essential copies of metal shell reports; and furnish complete experiences expected by this specification to the one that has done the manufacture of your cylinders and, on ask for, towards the purchaser.

(one) For spheres the check need to be in the weld involving parallel metal plates with a push with welded seam at correct angles on the plates.

The metal Employed in the construction on the cylinder should be as specified in table 1 of appendix A to this element. The cylinder company should keep a history of deliberately extra alloying features.

(two) All capabilities done by, or on behalf of, the individual whose name or symbol seems as Section of the marking conform to demands laid out in this component.

Markings on Just about every container have to be stamped plainly and completely over a everlasting attachment or over a steel nameplate completely secured into the container by indicates aside from smooth solder.

A “root” bend take a look at specimen have to be Slice with the cylinder more info or welded take a look at plate, utilized for the tensile test laid out in paragraph (l)(one) of this section and from almost every other seam or equal welded check plate if the seam is welded by a technique unique from that used for the key seam.

(ii) Taper threads have to be of a length not a lot less than as specified for American Conventional taper pipe threads.

(ii) One cylinder has to be chosen from Each individual great deal and be hydrostatically pressure analyzed to destruction. If this cylinder bursts below 5 (5) occasions the services stress, then two further cylinders with the exact large amount given that the Beforehand examined cylinder need to be selected and subjected to this examination.
