(iii) Obtaining a Licensed Verify Evaluation on a person cylinder out of each and every number of two hundred cylinders or much less, if a certificate containing information to point compliance with the fabric specification is received.
(iii) If resulting from welded attachments on the highest head There exists inadequate surface area from which to take a specimen, it may be taken from a representative head of exactly the same warmth treatment method as being the check cylinder.
(1) Every single opening within the container need to be provided using a fitting, manager or pad of weldable stainless steel securely connected to your container by fusion welding.
(i) The remaining cylinders in the good deal need to be tested via the proof strain, drinking water-jacket, or immediate growth test system as prescribed in CGA C-1. The bare minimum take a look at strain should be preserved for the specific timeframe plus the screening machines need to be calibrated as prescribed in CGA C-one.
Stress-retaining supplies must be identified by any acceptable system that does not compromise the integrity in the cylinder. Plates and billets for hotdrawn cylinders have to be marked with the heat number.
Substance needs to be recognized by any acceptable technique besides that plates and billets for hotdrawn cylinders needs to be marked with the warmth variety.
Strain-retaining product should be recognized by any acceptable process that doesn't compromise the integrity with the cylinder. Plates and billets for hotdrawn cylinders needs to be marked with the warmth selection.
(iii) Once the dimension of a cylinder doesn't allow securing straight specimens, the specimens may very well be taken in almost any area or direction and will be straightened or flattened chilly, by strain only, not by blows.
Specimens taken across the circumferentially welded seam has to be Slash from a single cylinder taken at random from Every number of 200 or a lot less cylinders following heat cure and will have to move satisfactorily the subsequent tests:
(three) Name plates are authorized, supplied that they can be permanently and securely attached to the cylinder. Attachment by possibly brazing or welding isn't permitted. Attachment by soldering is permitted supplied steel temperature does not exceed five hundred °File.
(vii) The influence Qualities of every set of affect specimens might not be under the values in the next table:
(ii) In using the “extension underneath load” system, the entire pressure (or “extension beneath load”) equivalent to the worry at which the 0.2 p.c long-lasting strain takes place may very well be established with ample accuracy by calculating the elastic extension of the gauge size less than acceptable load and adding thereto 0.
Markings on Each individual cylinder has to be by stamping plainly and completely on shoulder, prime head, neck or valve defense collar which happens to be forever attached for the cylinders and forming an integral aspect thereof, furnished that cylinders not less than 0.090 inch thick might be stamped within the side wall adjacent to leading head.
(six) Intermediate manganese steels might be tempered at temperatures not below 1150 °File., and following heat dealing with Each individual cylinder has to be submitted to some magnetic examination to detect the existence of quenching cracks. Cracked cylinders should be get more info rejected and wrecked.
