(iii) Make copies of all composed notifications accessible for inspection by a agent of your Department.
(two) Warmth treatment method isn't expected after the welding or brazing of weldable lower carbon elements to attachments of comparable material which have been Beforehand welded or brazed to the highest or bottom of cylinders and effectively heat treated, provided such subsequent welding or brazing would not develop a temperature in excessive of 400 °File in any Component of the very best or base material.
(ii) In using the “extension under load” method, the overall strain (or “extension less than load”), corresponding to the stress at which the 0.2 p.c lasting strain occurs might be identified with enough accuracy by calculating the elastic expansion of your gauge size below appropriate load and introducing thereto 0.
(iii) Straight threads have to have at the least 4 engaged threads, limited in shape and calculated shear power at least ten instances the check tension on the cylinder. Gaskets, which avoid leakage and are inert to your dangerous material, are demanded.
(1) Specimens need to be taken from 1 cylinder immediately after heat remedy as illustrated in appendix A to this subpart, picked out at random from Each and every lots of 200 or less, as follows:
(one) Just about every cylinder need to be uniformly and adequately warmth handled prior to test by the relevant system demonstrated in table 1 of appendix A to this section. Warmth procedure have to be accomplished In the end forming and welding functions, except that when brazed joints are used, heat therapy must abide by any forming and welding functions, but can be accomplished in advance of, during or after the brazing functions (see paragraph (m) of the segment for weld repairs).
This exam may be made use of and must be as required by CGA C-three. The specimen needs to be bent right until the elongation at the outer area, adjacent to the foundation of your weld, between the evenly scribed gage strains a to b, have to be no less than twenty %, except that this share may be decreased for steels aquiring a tensile energy in excess of fifty,000 psig, as provided in paragraph (k) of the portion.
(iv) All straight threads should have a minimum of 6 engaged threads, a decent healthy, and an element of safety in shear of at least ten within the take a look at stress of your cylinder. Shear pressure has to be calculated through the use of the suitable thread shear spot in accordance with NBS Handbook H-28.
(3) Every single specimen for the tension and Charpy impression exams need to be taken from your facet wall of a cylinder or from a hoop that has been heat addressed With all the concluded cylinders of which the specimens should be consultant. The axis of the specimens have to be parallel to the axis on the cylinder.
All spun cylinders and plugged cylinders need to be examined for leakage by gas or air tension just after the bottom is cleaned and is absolutely free from all humidity topic to the subsequent situations and constraints:
Markings on Just about every container need to be stamped plainly and completely on the long lasting attachment or on a metallic nameplate forever secured on the container by implies apart from soft solder.
(two) A spun cylinder is one in website which an close closure from the completed cylinder continues to be welded by the spinning process.

(iii) For the goal of pressure measurement, the initial strain reference should be set even though the specimen is underneath a worry of 12,000 psi and also the strain indicator reading through currently being established for the calculated corresponding pressure.
