Each container have to be hydraulically pressurized inside of a water jacket to at the least one hundred pc, but not over one hundred ten per cent, in the take a look at tension and managed at this stress for no less than three minutes. Overall and long lasting expansion need to be recorded and included in the inspector's report.

(iii) For the objective of strain measurement, the Preliminary pressure have to be set when the specimen is beneath a tension of twelve,000 psi as well as strain indicator looking through becoming set for the calculated corresponding pressure.

A root bend exam specimen have to be Slice within the cylinder or welded exam plate, employed for the tensile examination specified in paragraph (n)(1) of the portion. Specimens needs to be organized and tested in accordance with and should meet the requirements of CGA Pamphlet C-three.

Standard taper pipe threads demanded in all openings. The size of your opening will not be lower than as specified for American Conventional pipe threads; tapped to gauge; thoroughly clean Slash, even, and without having checks.

(one) Specimens have to be taken from 1 cylinder just after warmth remedy as illustrated in appendix A to this subpart, decided on at random from Each individual large amount of 200 or less, as follows:

(ii) To the “extension under load” strategy, the entire strain (or extension under load) comparable to the tension at which the 0.2 p.c everlasting pressure occurs may very well be identified with sufficient accuracy by calculating the elastic extension of the gage size below suitable load and adding thereto 0.

Attachments for the container are approved by fusion welding furnished that this kind of attachments are created of weldable stainless-steel in accordance with paragraph (b) of this segment.

Reheat remedy of turned down cylinders is authorized. Subsequent thereto, cylinders will have to move all prescribed exams for being acceptable. Fix of welded seams by welding is authorized.

Heads connected by brazing should have a driving healthy With all the shell, Until the shell is crimped, swedged, or curled over the skirt or flange of the head, and be extensively brazed until eventually entire penetration by the brazing materials on the brazed joint is secured. Depth of brazing with the joint must be a minimum of 4 (4) moments the minimal thickness of shell metal.

(four) As a safety precaution, When the company elects to create this examination prior to the hydrostatic test, he should style and design his apparatus so the stress is placed on the smallest area practicable, throughout the point of closure, and in order to utilize the smallest achievable volume of air or fuel.

(3) The Charpy V-notch influence Qualities with the 3 effect specimens which should be analyzed at 0 °F is probably not fewer than the values proven as follows:

A “root” bend take a look at specimen should be Slice within the cylinder or welded test plate, used for the tensile check specified in paragraph (l)(one) of the section and from any other seam or equal welded test plate In the event the seam is welded by a technique distinctive from that useful for the foremost seam.

(iii) The minimal examination pressure has to be managed at the very least 30 website seconds and sufficiently more time to be certain full growth. Any inside force utilized just after warmth-treatment and prior to the Formal exam may not exceed ninety % from the test tension.

(two) The heads need to be seamless, concave facet to your strain, hemispherical or ellipsoidal in form with the key diameter not in excess of two times the slight diameter.
