(two) The look service temperature may be the coldest temperature for which a cylinder is suitable. The needed design service temperatures for each cryogenic liquid is as follows:

A Actual physical take a look at need to be performed to ascertain yield energy, tensile toughness, elongation, and reduction of region of material as follows:

(2) Each and every cylinder have to fulfill the following further prerequisite which assumes a cylinder horizontally supported at its two ends and uniformly loaded around its overall duration.

(iii) Straight threads must have not less than 4 engaged threads, limited match and calculated shear strength not less than ten times the examination tension with the cylinder. Gaskets, which prevent leakage and they are inert towards the harmful content, are essential.

(three) For filling that is certainly molded and dried ahead of insertion in cylinders, porosity exam could be created on sample block taken at random from content for use.

The eCFR is displayed with paragraphs break up and indented to follow the hierarchy on the document. This is an automatic procedure for person advantage only and isn't meant to alter agency intent or current codification.

(one) No defect is permitted that is probably going to weaken the completed cylinder appreciably. A fairly easy and uniform surface area is required.

(B) With information and facts specifying the sort(s) and dimensions with the closures, like gaskets and another components needed making sure that the packaging is capable of effectively passing the applicable effectiveness exams. This data must involve any methods to become adopted, which includes closure Recommendations for inner packagings and receptacles, to successfully assemble and close the packaging for the purpose of protecting against leakage in transportation.

The steel Utilized in the development in the cylinder has to be as specified in table 1 of appendix A to this component. The cylinder manufacturer must retain a file of deliberately additional alloying components.

As well as the necessities of § 178.35, check here the inspector's report for that Bodily take a look at report, will have to point out the common benefit for three specimens plus the bare minimum price for 1 specimen for each ton amount.

(vii) The impression Houses of each set of effect specimens may not be less than the values in the subsequent desk:

This Make contact with form is just for Web page enable or Web-site ideas. When you've got concerns or opinions relating to a published doc please Call the publishing company.

(seven) Except as if not offered in paragraph (g)(6) of this part, all cylinders, if water quenched or quenched using a liquid creating a cooling fee in surplus of 80 percent on the cooling amount of h2o, need to be inspected through the magnetic particle, dye penetrant or ultrasonic process to detect the existence of quenching cracks. Any cylinder meant to the requirements for specification 3AA and located to possess a quenching crack needs to be turned down and might not be requalified.

Cylinders must be created applying equipment and processes satisfactory to ensure that Every cylinder produced conforms to the requirements of the subpart and the next:
