(iii) When size of the cylinder would not permit securing straight specimens, the specimens can be taken in any location or course and will be straightened or flattened cold by tension only, not by blows.
Welding or brazing for virtually any purpose in anyway is prohibited except that welding is approved for that attachment of neckrings and footrings which are nonpressure pieces, and only to your tops and bottoms of cylinders.
(4) As a safety precaution, If your maker elects to make this check before the hydrostatic check, the producer should really design the exam equipment so the pressure is applied to the smallest spot practicable, round the place of closure, and so as to utilize the smallest feasible quantity of air or gasoline.
One particular cylinder taken at random out of each number of two hundred or significantly less, must be subjected into a flattening examination as follows:
(i) If the selected cylinder passes the water-jacket or immediate expansion examination, the remaining cylinders in Each and every whole lot has to be strain examined by the evidence force water-jacket or direct enlargement take a look at approach as prescribed in CGA C-one.
(iii) For the purpose of pressure measurement, the Preliminary pressure should be set when the specimen is below a pressure of twelve,000 psig and the strain indicator looking through must be set in the calculated corresponding strain.
(2) Every single opening in the spherical sort cylinder have to be delivered using a fitting, boss, or pad of weldable metal securely connected into the container by fusion welding.
(iii) In the event the sizing of the cylinder will not permit securing straight specimens, the specimens may very well be taken in any location or way and could be straightened or flattened cold, by force only, not by blows.
(two) Heat cure is not really needed right after welding or brazing weldable very low carbon sections to attachments, specified in paragraph (file)(1) of the part, of similar materials that have been Earlier welded or brazed to the very best or base of cylinders and adequately heat treated, delivered these subsequent welding or brazing isn't going to generate a temperature in excessive of 400 °File in almost any Component of the very best or bottom product.
(1) Circumferential seams have to be by brazing only. Heads has to be attached to here shells through the lap brazing approach and must overlap not under four situations the wall thickness. Brazing materials needs to have a melting level of not a lot less than 1000 °F.
Cylinders needs to be created applying machines and processes ample making sure that Just about every cylinder generated conforms to the requirements of the subpart. No defect is permitted that is likely to weaken the finished cylinder appreciably.
(3) The floor of the cylinder need to be insulated. The insulating content must be fire resistant. The insulation on non-evacuated jackets must be lined with a steel jacket not a lot less than 0.060-inch thick or an aluminum jacket not lower than 0.070 inch thick, so produced that humidity are not able to are available connection with the insulating materials. If a vacuum is taken care of from the insulation House, the evacuated jacket has to be created for a least collapsing force of thirty psig differential whether or not crafted from metal or aluminum.
(b) Every single these kinds of 25,000 containers or much less, successively manufactured daily, shall constitute quite a bit and if the exam container shall are unsuccessful, the ton shall be rejected or ten further containers could possibly be selected at random and subjected on the take a look at less than which failure happened.
(1) The effects on the test must conform to no less than the minimum amount suitable mechanical residence limits for aluminum alloys as specified in paragraph (b) of the section.
