(ii) Taper threads needs to be of a length not a lot less than that specified for American Standard taper pipe threads.

The fabric have to be recognized by any suited technique except that plates and billets For decent-drawn cylinders has to be marked with the heat selection.

(iii) When measurement of cylinder would not allow securing straight specimens, the specimens could be taken in almost any place or path and should be straightened or flattened chilly by tension only, not by blows.

Marking on Each individual container by stamping plainly and completely are only licensed where by the metallic is at the least 0.09 inch thick, or over a metal nameplate forever secured for the container by signifies in addition to comfortable solder, or by usually means that might not decrease the wall thickness.

(i) If the selected cylinder passes the drinking water-jacket or direct growth check, the remaining cylinders in Every single ton needs to be tension analyzed from the proof pressure drinking water-jacket or direct growth take a look at system as prescribed in CGA C-one.

(iv) Long lasting volumetric growth may well not exceed 10 percent of the overall volumetric growth at test strain.

(iii) The minimal examination force needs to be preserved not less than 30 seconds and sufficiently for a longer period to make sure comprehensive enlargement. Any internal force applied immediately after heat-therapy and ahead of the official exam might not exceed 90 % of the take a look at force.

(1) All seams in the cylinder need to be fusion welded. A get more info means needs to be offered for carrying out entire penetration from the joint. Only butt or joggle butt joints with the cylinder seams are approved. All joints in the cylinder needs to have moderately accurate alignment.

Ends: The highest in the container needs to be developed that has a stress relief technique consisting of radial scores on the very best seam(s). The bottom in the container must be made to buckle in a stress increased compared to stress at which the best buckles and vents.

(four) As a security precaution, Should the producer elects to generate this test prior to the hydrostatic test, he should really structure his equipment so that the strain is placed on the smallest location practicable, around the level of closure, and so as to utilize the smallest achievable volume of air or fuel.

(iii) The least exam force must be taken care of at the very least thirty seconds and sufficiently extended to make certain entire expansion. Any inner stress utilized following warmth-cure and ahead of the Formal take a look at may not exceed 90 percent with the take a look at stress.

A “root” bend test specimen has to be Slice with the cylinder or welded take a look at plate, employed for the tensile take a look at specified in paragraph (l)(one) of this part and from another seam or equal welded examination plate In case the seam is welded by a treatment diverse from that used for the most important seam.

(ii) In using the “extension beneath load” approach, the full strain (or “extension under load”) comparable to the strain at which the 0.two percent long lasting pressure takes place can be established with adequate accuracy by calculating the elastic extension from the gauge length beneath proper load and adding thereto 0.
