(i) The remaining cylinders in Each and every great deal have to be analyzed because of the evidence tension, h2o-jacket, or direct expansion check approach as prescribed in CGA C-1. The bare minimum examination stress has to be managed for the precise timeframe as well as tests equipment has to be calibrated as prescribed in CGA C-1.
(1) Pressurization have to be done hydrostatically concerning around zero psig as well as the support force in a level not in excess of 10 cycles per moment. Suitable recording instrumentation need to be furnished if products is usually to be remaining unattended for periods of time.
Strain-retaining components must be discovered by any suited technique that doesn't compromise the integrity in the cylinder. Plates and billets for hotdrawn cylinders needs to be marked with the warmth range.
(ii) 1 cylinder need to be picked from Each and every large amount and be hydrostatically pressure tested to destruction. If this cylinder bursts under 5 (five) moments the assistance tension, then two additional cylinders in the identical whole lot as being the Beforehand examined cylinder must be picked and subjected to this check.
Stress-retaining products have to be recognized by any acceptable strategy that does not compromise the integrity with the cylinder. Plates and billets for hotdrawn cylinders has to be marked with the heat quantity.
(iii) Long lasting volumetric enlargement may not exceed ten percent of overall volumetric expansion at examination pressure.
(iii) For the goal of strain measurement, the First strain must be set even though the specimen is less than a strain of 12,000 psi, and also the pressure indicator reading have to be established for the calculated corresponding pressure.
All spun cylinders and plugged cylinders website has to be examined for leakage by gas or air pressure after The underside has actually been cleaned and is also free of charge from all moisture subject to the subsequent ailments and constraints:
Ends: The very best from the container must be built having a strain relief technique consisting of radial scores on the top seam(s). The bottom in the container have to be intended to buckle in a pressure higher when compared to the pressure at which the top buckles and vents.
(three) Name plates are licensed, provided that they may be permanently and securely connected for the cylinder. Attachment by both brazing or welding just isn't permitted. Attachment by soldering is permitted supplied metal temperature does not exceed five hundred °File.
One list of a few impact check specimens (for each examination) needs to be geared up and analyzed for determining the effects properties of the deposited weld metal—
(2) A company of a packaging subject matter to the requirements of the part is largely liable for compliance with the necessities of this aspect. On the other hand, anyone who performs a perform prescribed in this section shall accomplish that perform in accordance using this component.
(ii) One particular specimen need to be taken from both head over a cylinder when both of those heads are created of a similar product. Having said that, if The 2 heads are created of differing elements, a specimen need to be taken from Just about every head.
(2) The heads must be seamless, concave aspect on the tension, hemispherical or ellipsoidal in shape with the key diameter not more than twice the small diameter.
