Open hearth or electric powered furnace metal of uniform high-quality must be applied. A warmth of steel produced underneath the technical specs mentioned in Desk one On this paragraph (b), a Check out chemical Investigation that is definitely slightly outside of the desired assortment is suitable, if satisfactory in all other respects, offered the tolerances proven in Desk two In this particular paragraph (b) are certainly not exceeded.
Mechanical tests should be conducted to find out generate energy, tensile strength, elongation for a share, and reduction of region of material as a percentage, as follows:
(1) A spun cylinder is a person wherein an conclusion closure within the completed cylinder has been welded from the spinning approach.
(iii) Straight threads must have at the very least four engaged threads, restricted match and calculated shear strength at the very least ten occasions the check strain in the cylinder. Gaskets, which avoid leakage and so are inert to your harmful material, are required.
Mend of welded seams by welding prior to procedure treatment is approved. Subsequent thereto, containers must be warmth dealt with and move all prescribed exams.
The eCFR is displayed with paragraphs split and indented to Keep to the hierarchy of the document. This can be an automated system for user comfort only and isn't intended to change company intent or current codification.
This exam can be employed and need to be as demanded by CGA C-three. The specimen need to be bent right up until the elongation for the outer surface, adjacent to the basis in the weld, between the evenly scribed gage lines a to b, should be at the very least 20 p.c, except that this percentage might be decreased for steels using a tensile strength in excess of 50,000 psig, as delivered in paragraph (k) of the segment.
(B) With facts specifying the kind(s) and dimensions in the closures, which includes gaskets and every other parts desired to ensure that the packaging is capable of properly passing the applicable performance exams. This details will have to include any strategies being followed, together with closure Directions for internal packagings and receptacles, to effectively assemble and shut the packaging for the purpose of avoiding leakage in transportation.

In combination with the data demanded by § 178.35, the report of chemical analyses will have to also involve the alloy designation, and relevant information on iron, titanium, zinc, magnesium and some other relevant factor Employed in the construction of the cylinder.
(1) Openings are permitted in heads only. They need to be round and will not exceed three inches in diameter or just one 3rd in the cylinder diameter, whichever is considerably less. Each individual opening while in the cylinder should be furnished by using a fitting, manager or pad, possibly integral with, or securely connected to, the cylinder body by fusion welding.
(ii) The specimen, special of grip finishes, may not be flattened. Grip finishes can be flattened to inside of one inch of each and every finish on the lowered section. Heating on the specimen for almost any intent just isn't authorized.
Cylinders needs to be produced applying products and procedures satisfactory in order that each cylinder generated conforms to the requirements of this subpart. No fissure or other defect is permitted that is likely to weaken the completed cylinder appreciably. A fairly sleek and uniform surface area end is required. Otherwise initially no cost from this sort of defects, the surface can be machined or normally addressed to reduce these defects.
Reheat treatment method of rejected cylinder is approved. Subsequent thereto, cylinders should go all prescribed exams for being suitable. Mend by welding check here is licensed.
