(three) On a plate attached to the highest from the cylinder or permanent component thereof: sufficient Place must be remaining about the plate to offer for stamping at least 6 retest dates: the plate has to be at least one⁄sixteen inch thick and need to be hooked up by welding or by brazing at a temperature of at the very least 1100 °F, through all edges from the plate.

(i) The remaining cylinders in Each individual whole lot has to be strain tested from the proof pressure, water-jacket or direct enlargement exam strategy as prescribed in CGA C-1. The minimal test strain should be managed for the specific timeframe as well as the tests devices have to be calibrated as prescribed in CGA C-one.

A root bend examination specimen needs to be Slash through the cylinder or welded test plate, used for the tensile take a look at specified in paragraph (n)(one) of this portion. Specimens needs to be prepared and analyzed in accordance with and will have to fulfill the requirements of CGA Pamphlet C-3.

Reheat therapy is licensed for rejected cylinders. Subsequent thereto, cylinders must move all prescribed assessments to become acceptable. Fix by welding or spinning is just not approved.

A specimen have to be faraway from 1 cylinder of every lot of 200 or fewer, or welded test plate. The welded check plate have to be of on the list of heats inside the number of two hundred or much less which it signifies, in the identical condition and somewhere around the same thickness given that the cylinder wall apart from that in no situation ought to it be of a lesser thickness than that expected for a quarter dimensions Charpy effects specimen. The weld needs to be produced by exactly the same techniques and subjected to exactly the same heat therapy as the main weld about the cylinder.

(3) Just about every exam cylinder should endure flattening to 9 situations the wall thickness with out cracking. In the event the alternate bend examination is employed, the test specimens have to continue to be uncracked when bent inward about a mandrel in the way of curvature with the cylinder wall until the interior edges are in a distance aside not higher as opposed to diameter in the mandrel.

(iv) Long-lasting volumetric expansion may well not exceed 10 per cent of the overall volumetric expansion at examination pressure.

(iii) The minimal check force needs to be managed at least 30 seconds and sufficiently for a longer period bar178 to ensure complete enlargement. Any inside strain applied soon after heat-procedure and just before the Formal examination may well not exceed 90 p.c in the exam strain.

Cylinders should be manufactured using gear and procedures adequate to make certain Just about every cylinder manufactured conforms to the requirements of the subpart. No defect is permitted that is probably going to weaken the finished cylinder appreciably.

A specimen need to be Slash from just one cylinder of every lot of two hundred or less, or perhaps a welded test plate. The welded test plate needs to be of among the list of heats while in the large amount of 200 or much less which it signifies, in precisely the same ailment and about exactly the same thickness as being the cylinder wall besides that it may not be of a lesser thickness than that needed for 1 / 4 dimension Charpy affect specimen. The weld should be made by precisely the same treatments and subjected to the same heat therapy as the main weld to the cylinder.

Cylinders have to be created making use of equipment and procedures sufficient making sure that each cylinder created conforms to the necessities of the subpart. No defect is permitted that is likely to weaken the finished cylinder appreciably.

This Web-site is utilizing a protection assistance to guard itself from on-line assaults. The action you just executed induced the safety Option. There are plenty of actions that may result in this block which include submitting a particular term or phrase, a SQL command or malformed details.

(one) The check need to be amongst knife edges, wedge shaped, aquiring a sixty° bundled angle, and rounded in accordance with the following table. The longitudinal axis with the cylinder must be at an angle 90° on the knife edges in the take a look at. The flattening examination desk is as follows:

Ends: The finishes shall be built to face up to force plus the container Outfitted which has a force aid method (e.g., rim-venting release or possibly a dome growth product) meant to buckle prior to the burst from the container.
