The attachment on the tops and bottoms only of cylinders by welding of neckrings, footrings, handles, bosses, pads and valve security rings is licensed delivered that such attachments as well as the portion of the container to which These are connected are created of weldable steel, the carbon content of which can not exceed 0.twenty five %.
The material need to be discovered by any acceptable method apart from that plates and billets For decent-drawn cylinders should be marked with the warmth quantity.
(2) Just about every cylinder ought to meet up with the subsequent additional need which assumes a cylinder horizontally supported at its two finishes and uniformly loaded around its full duration.
Cylinders should be created using gear and processes sufficient to ensure that Every cylinder created conforms to the necessities of this subpart. No defect is permitted that is likely to weaken the completed cylinder appreciably.
(two) All attachments to your sidewalls and heads from the cylinder need to be by fusion welding and should be of the weldable materials complying Along with the impression prerequisites of paragraph (l) of this segment.
A mechanical take a look at has to be carried out to determine generate energy, tensile toughness, elongation as a proportion, and reduction of space of fabric to be a percentage as follows:
Attachments to the container are licensed by fusion welding presented that these attachments are made of weldable chrome steel in accordance with paragraph (b) of the portion.
(B) With info specifying the type(s) and Proportions in the closures, which includes gaskets and any other factors necessary to ensure that the packaging is capable of efficiently passing the applicable functionality exams.

The metal used in the construction of your cylinder need to be as laid out in desk one of appendix A to this element. The cylinder manufacturer must manage a history of intentionally extra alloying things.
S = PD/4tE In which: S = wall worry in psig; P = minimal exam strain prescribed for drinking water jacket exam; D = outdoors diameter in inches; t = least wall thickness in inches; E = 0.
(iii) Straight threads, possessing no less than four engaged threads, to own tight in shape and calculated shear toughness no less than ten situations the examination pressure on the container; gaskets demanded, sufficient to avoid leakage.
(ii) Taper threads to become of duration not under as specified for American Standard taper pipe threads.
(ii) Taper threads need to be of the size not lower than as specified for American bar178 Typical taper pipe threads.
Just one completed cylinder selected at random out of every lots of five hundred or fewer successively made must be hydrostatically examined to 4
