All spun cylinders and plugged cylinders have to be examined for leakage by dry fuel or dry air stress after The underside continues to be cleaned and is also free of charge from all dampness, matter to the next ailments and limitations:

(iii) When size in the cylinder will not permit securing straight specimens, the specimens may be taken in almost any area or way and could be straightened or flattened cold, by strain only, not by blows.

A Bodily take a look at must be carried out to find out produce power, tensile energy, and elongation as follows:

Cylinders must be produced working with machines and procedures ample to make sure that Every single cylinder generated conforms to the requirements of the subpart. No defect is permitted that is probably going to weaken the completed cylinder appreciably.

Radiographic examinations is needed on all welded joints which can be subjected to inside strain, except that on the discretion on the disinterested inspector, openings below twenty five per cent in the sphere diameter needn't be subjected to radiographic inspection. Proof of any defects likely to critically weaken the container has to be induce for rejection.

Reheat procedure of rejected cylinders is licensed 1 time. Subsequent thereto, cylinders need to pass all prescribed exams being suitable.

(four) Establish porosity of filling and tare weights; verify compliance of marking with prescribed needs; acquire important copies of steel shell studies; and furnish entire reports expected by this specification to the one that has finished the manufacture of your cylinders and, upon ask for, into the purchaser.

(iv) Everlasting volumetric expansion may not exceed ten % of the full volumetric enlargement at take a look at pressure.

A single container taken at random from two hundred or considerably less has to be hydrostatically examined to destruction. Rupture stress need to be included as A part of the inspector's report.

(i) The remaining cylinders in each whole lot should be analyzed through the proof force h2o-jacket or immediate enlargement take a look at technique as prescribed in CGA C-one. The minimum amount examination strain has to be taken care of for the precise timeframe as well as the testing tools have to be calibrated as prescribed in CGA C-1.

(iv) Permanent volumetric growth may well not exceed 10 % of the full volumetric enlargement at exam force.

A “root” bend take a look at specimen need to be cut in the cylinder or welded exam plate, useful for the tensile examination specified in paragraph (l)(one) of this section and from some other seam or equal welded take a look at plate When the seam is welded by a course of action unique from that employed for the foremost seam.

(ii) more info In using the “extension below load” method, the full strain (or “extension beneath load”) corresponding to the stress at which the 0.two % everlasting strain occurs may very well be decided with adequate precision by calculating the elastic extension of the gauge duration underneath ideal load and adding thereto 0.

(six) Intermediate manganese steels may very well be tempered at temperatures not fewer than 1150 °File., and soon after warmth treating Every cylinder should be submitted to your magnetic examination to detect the presence of quenching cracks. Cracked cylinders should be turned down and wrecked.
