One sphere taken at random out of every lots of 200 or much less need to be subjected to your flattening take a look at as follows:

(iii) Straight threads, possessing no less than 4 engaged threads, to own restricted suit and calculated shear toughness not less than 10 times the check stress of your container; gaskets expected, enough to circumvent leakage.

(1) The take a look at have to be concerning knife edges, wedge formed, having a sixty° incorporated angle, and rounded in accordance with the next table. The longitudinal axis of the cylinder needs to be at an angle 90° into the knife edges in the examination. The flattening test desk is as follows:

Reheat remedy of turned down cylinders is authorized. Subsequent thereto, cylinders will have to go all prescribed exams to be suitable. Restore of welded seams by welding is licensed.

(1) No defect is permitted that is likely to weaken the finished cylinder appreciably. A fairly sleek and uniform surface is required.

At or before the time of delivery for the purchaser, the cylinder producer have to have all accomplished certification paperwork mentioned in CGA C-11. The producer of your cylinders ought to retain the studies necessary by this subpart for 15 decades from the first take a look at date with the cylinder.

(iii) For the objective of strain measurement, the initial pressure need to be set whilst the specimen is beneath a anxiety of 12,000 psi and also the pressure indicator reading through staying established within the calculated corresponding strain.

(two) All seams in the sphere or cylinders should be fusion welded. Seams must be with the butt or joggle butt form and suggests need to be presented for accomplishing finish penetration of your joint.

(2) All attachments towards the sidewalls and heads on the cylinder need to be by fusion welding and have to be of the weldable content complying Using the impact requirements of paragraph (l) of the part.

The least wall thickness with the cylinder need to be this sort of that the calculated wall tension in the minimum required exam tension might not exceed the the very least price of the next:

(iv) Long lasting volumetric expansion might not exceed ten per cent of the entire volumetric enlargement at take a look at stress.

(i) If the chosen cylinder passes the drinking water-jacket or direct growth check, the remaining cylinders in Every great deal have to be strain tested with the evidence read more pressure drinking water-jacket or direct enlargement take a look at approach as prescribed in CGA C-1.

(ii) In using the “extension underneath load” process, the total strain (or “extension underneath load”) similar to the stress at which the 0.2 % long-lasting strain occurs might be decided with adequate accuracy by calculating the elastic extension on the gauge size below proper load and including thereto 0.

(iv) Long term volumetric expansion may well not exceed ten per cent of the overall volumetric expansion at take a look at tension.
