The attachment for the tops and bottoms only of cylinders by welding of neckrings, footrings, handles, bosses, pads and valve safety rings is approved presented that these attachments along with the percentage of the container to which They are really connected are created of weldable steel, the carbon content of which can not exceed 0.25 percent.
(two) Heat therapy just isn't required after the welding or brazing of weldable lower carbon areas to attachments of similar product which have been previously welded or brazed to the best or bottom of cylinders and adequately heat taken care of, delivered such subsequent welding or brazing won't create a temperature in extra of 400 °F in almost any A part of the top or bottom materials.
(iv) Over a steel plate connected to the best from the cylinder or everlasting part thereof; ample House need to be left over the plate to offer for stamping no less than 6 retest dates; the plate has to be at the least one⁄sixteen-inch thick and need to be hooked up by welding, or by brazing.
Marking need to be carried out by stamping in the metallic of your cylinder. All markings need to be legible and Found over a shoulder.
(iii) The subsequent system needs to be accustomed to determine the most longitudinal tensile strain as a result of hydrostatic check tension:
The eCFR is exhibited with paragraphs split and indented to Keep to the hierarchy of the document. This is certainly an automated procedure for person convenience only and isn't intended to alter agency intent or existing codification.
(i) Nonflammable cryogenic liquids. Cylinders meant for use during the transportation of nonflammable cryogenic liquid should have an outer jacket product of metal or aluminum.
(ii) In utilizing the “extension below load” method, the whole pressure (or “extension under load”) akin to the worry at which the 0.two per cent long term pressure happens might be determined with ample accuracy by calculating the elastic extension with the gauge length beneath proper load and adding thereto 0.
(three) A plugged cylinder is one during which a long lasting closure in The underside of a finished cylinder is effected by a plug.
(one) Each individual cylinder must be heated and held at the appropriate temperature for at least 1 hour for every inch of thickness based upon the maximum thickness from the cylinder and website then quenched in an acceptable liquid medium using a cooling fee not in excessive of eighty percent of drinking water.
(one) Stress, about similar to but no a lot less than provider pressure, have to be applied to just one aspect of your concluded base around a region of no less than 1⁄16 of the total location of The underside although not a lot less than 3⁄four inch in diameter, such as the closure, for a minimum of one minute, during which period another facet of the bottom subjected to tension need to be coated with drinking water and intently examined for indications of leakage. Besides as offered in paragraph (n) of this portion, a cylinder that may be leaking have to be rejected.
Heads formed by drawing or urgent needs to be uniformly and appropriately warmth taken care of previous to assessments. Cylinders with integral fashioned heads or bases must be subjected to the normalizing Procedure.
Markings on Every single cylinder need to be by stamping plainly and completely on shoulder, best head, neck or valve safety collar which can be permanently attached towards the cylinders and forming an integral element thereof, presented that cylinders not lower than 0.090 inch thick could be stamped around the aspect wall adjacent to best head.
Finishes: The finishes shall be made to withstand strain and the container Geared up that has a stress relief procedure (e.g., rim-venting launch or simply a dome growth unit) designed to buckle before the burst of your container.
