(2) Warmth therapy is just not required following the welding or brazing of weldable low carbon areas to attachments of comparable material which have been Earlier welded or brazed to the top or bottom of cylinders and adequately heat handled, presented these types of subsequent welding or brazing will not develop a temperature in excess of 400 °F in almost any Element of the top or bottom substance.

(one) Pressure, somewhere around similar to but no below services strain, have to be placed on one particular side of your finished bottom above a location of no less than one⁄sixteen of the full area of the bottom but not lower than 3⁄4 inch in diameter, including the closure, for at least 1 minute, throughout which time another aspect of The underside exposed to strain must be lined with h2o and closely examined for indications of leakage. Other than as delivered in paragraph (n) of this area, cylinders which are leaking have to be turned down.

Reheat cure is licensed for turned down cylinders. Subsequent thereto, cylinders must pass all prescribed tests for being satisfactory. Fix by welding or spinning is just not approved.

(3) For filling that is certainly molded and dried before insertion in cylinders, porosity examination may very well be created on sample block taken at random from product to be used.

The eCFR is shown with paragraphs split and indented to Adhere to the hierarchy on the document. This is certainly an automated system for consumer convenience only and isn't meant to alter company intent or existing codification.

The cylinder base will need to have a primary torispherical, hemispherical, or ellipsoidal interior base configuration where by the dish radius isn't any increased than one.

All spun cylinders and plugged cylinders has to be analyzed for leakage by fuel or air stress after the bottom has become cleaned which is totally free from all dampness, matter to the next circumstances:

A specimen have to be Lower from 1 cylinder of each number of two hundred or considerably less, or welded check plate. The specimen must be taken from through the key seam and has to be prepared and examined in accordance with and need to meet the necessities of CGA Pamphlet C-3.

A specimen has to be Slash from a single cylinder of each and every great deal of two hundred or much less, or maybe a welded test plate. The welded examination plate must be of one of many heats during the great deal of two hundred or fewer which it represents, in precisely the same ailment and roughly the exact same thickness given that the cylinder wall besides that it will not be of the lesser thickness than that required for a quarter measurement Charpy impression specimen. The weld must be made by the exact same strategies and subjected to the same heat procedure as the key weld about the cylinder.

(iii) With a cylindrical portion of the shell that extends past the recessed bottom with the cylinder, constituting an integral and non-pressure A part of the cylinder;

(ii) The filling content have to 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 effectively is full of a cloth of these form the functions of the filling product are certainly not impaired;
