Open up hearth or electric furnace steel of uniform high-quality need to be employed. A heat of steel built beneath the technical specs detailed in Desk 1 On this paragraph (b), a check chemical Evaluation that may be a bit out of the specified range is appropriate, if satisfactory in all other respects, delivered the tolerances demonstrated in Table 2 Within this paragraph (b) aren't exceeded.
(two) Warmth remedy is not really required soon after welding of weldable very low-carbon elements to attachments of comparable material that have been Formerly welded to the highest or bottom of cylinders and thoroughly warmth taken care of, offered this kind of subsequent welding does not deliver a temperature in excessive of four hundred °F in almost any Component of the highest or base material.
Marking on Every container by stamping plainly and permanently are only approved exactly where the metal is not less than 0.09 inch thick, or on the metallic nameplate forever secured for the container by usually means apart from delicate solder, or by suggests that might not decrease the wall thickness.
(ii) In using the “extension less than load” system, the overall strain (or “extension under load”) corresponding to the tension at which the 0.2 per cent long lasting strain occurs could be decided with sufficient accuracy by calculating the elastic extension with the gauge length under appropriate load and incorporating thereto 0.
(ii) In utilizing the “extension under load” approach, the whole strain (or “extension less than load”) comparable to the tension at which the 0.two % long-lasting strain takes place may be identified with enough accuracy by calculating the elastic extension from the gauge duration less than suitable load and introducing thereto 0.
(2) Each individual opening inside of a spherical kind of cylinder have to be delivered that has a fitting, manager, or pad of weldable metal securely hooked up for the cylinder by fusion welding.
The steel Employed in the development of your cylinder has to be as laid out in desk 1 of appendix A to this part. The cylinder producer have to maintain a file of intentionally extra alloying features.
(i) The porous content may well not disintegrate bar 178 rtp or sag when damp with solvent or when subjected to typical services;
(1) Each and every stress specimen will need to have a gauge size of two inches by using a width not exceeding a single and 1-50 % inches. Apart from the grip ends, the specimen is probably not flattened. The grip finishes could possibly be flattened to inside of 1 inch of each and every conclude in the decreased portion.
(i) The remaining cylinders in Each individual large amount has to be tension tested because of the evidence pressure, water-jacket or direct expansion take a look at method as prescribed in CGA C-1. The minimal take a look at pressure should be taken care of for the particular timeframe along with the screening devices has to be calibrated as prescribed in CGA C-1.
The eCFR is shown with paragraphs break up and indented to Adhere to the hierarchy with the document. This really is an automatic approach for user advantage only and isn't intended to alter company intent or current codification.
Only open hearth, standard oxygen, or electrical furnace process metal of uniform excellent is licensed. The metal Assessment should conform to the next:
Heads fashioned by drawing or urgent should be uniformly and properly heat dealt with before checks. Cylinders with integral formed heads or bases have to be subjected into a normalizing Procedure.
S = PD/4tE Wherever: S = wall anxiety in psig; P = minimal take a look at force prescribed for water jacket test; D = outside the house diameter in inches; t = least wall thickness in inches; E = 0.
