(iii) When size of cylinder doesn't permit securing straight specimens, the specimens could be taken in any locale or route and will be straightened or flattened chilly, by force only, not by blows.

(two) Each and every opening inside a spherical kind of cylinder should be provided which has a fitting, manager, or pad of weldable metal securely hooked up for the cylinder by fusion welding.

(1) Every opening inside the container needs to be supplied using a fitting, boss or pad of weldable stainless-steel securely connected towards the container by fusion welding.

Only open hearth, primary oxygen, or electric powered furnace procedure steel of uniform high quality is approved. The metal Examination should conform to the next:

(1) Until otherwise mentioned, if a sample cylinder or specimen taken from a lot of cylinders fails the prescribed test, then two additional specimens must be picked through the same ton and subjected on the prescribed examination. If possibly of those fails the take a look at, then the complete great deal has to be turned down.

(4) As a security precaution, if the maker elects to produce this examination before the hydrostatic take a look at, he should design his equipment so that the force is placed on the smallest region practicable, throughout the point of closure, and in order to make use of the smallest attainable volume of air or fuel.

Strain-retaining product need to be determined by any suited method that doesn't compromise the integrity of your cylinder. Plates and billets for hotdrawn cylinders should be marked with the warmth variety.

(iii) Once the sizing of a cylinder will not allow securing straight specimens, the specimens may very well be taken in almost any site or route and could be straightened or flattened cold, by tension only, not by blows.

(4) Should the cylinder floor just isn't initially free from your defects, the surface could be machined or usually addressed to get rid of these defects supplied the minimum wall thickness is preserved.

(iv) A brass fitting may very well be brazed to the steel manager or flange on cylinders made use of as ingredient portions of handheld hearth extinguishers.

(ii) In using the “extension less than load” strategy, the full strain (or “extension underneath load”) comparable to the strain at which the 0.2 percent long-lasting pressure occurs may be identified with adequate precision by calculating the elastic get more info extension from the gauge size under correct load and including thereto 0.

(ii) Taper threads to get of duration not fewer than as specified for American Conventional taper pipe threads.

A single finished cylinder picked at random out of each great deal of five hundred or fewer successively manufactured needs to be hydrostatically tested to 4
