(ii) Taper threads being of length not less than as specified for American Regular taper pipe threads.
(one) Openings are permitted in heads only. They have to be circular and will not exceed 3 inches in diameter or just one third on the cylinder diameter, whichever is a lot less. Each opening from the cylinder must be offered which has a fitting, manager or pad, both integral with, or securely hooked up to, the cylinder system by fusion welding.
Content has to be determined by any suitable approach besides that plates and billets for hotdrawn cylinders have to be marked with the heat quantity.
(iii) For the purpose of pressure measurement, the Original pressure reference must be established although the specimen is under a anxiety of 12,000 psi plus the pressure indicator studying currently being established at the calculated corresponding pressure.
Attachments to your container are approved by fusion welding provided that these types of attachments are made of weldable stainless-steel in accordance with paragraph (b) of this portion.
(i) The remaining cylinders in Each and every great deal need to be analyzed with the evidence force h2o-jacket or direct growth exam approach as prescribed in CGA C-1. The minimum amount examination stress must be taken care of for the particular timeframe and also the tests tools have to be calibrated as prescribed in CGA C-1.
Following tension tests, a flattening test have to be executed on a single cylinder taken at random out of every wide range of 200 or fewer by placing the cylinder in between wedge-formed knife edges aquiring a sixty degree integrated angle, rounded to a 50 %-inch radius.
Reheat cure of turned down cylinders is authorized. Subsequent thereto, cylinders should move all prescribed tests being acceptable. Repair service by welding is licensed.
A specimen must be faraway from one particular cylinder of every large amount of two hundred or fewer, or welded examination plate. The welded examination plate have to be of one of many heats while in website the lots of two hundred or much less which it signifies, in the exact same affliction and somewhere around the identical thickness as being the cylinder wall other than that in no circumstance need to or not it's of a lesser thickness than that demanded for 1 / 4 dimensions Charpy affect specimen. The weld need to be produced by exactly the same procedures and subjected to a similar warmth procedure as the main weld within the cylinder.
(ii) In utilizing the “extension beneath load” technique, the overall strain (or “extension less than load”) comparable to the anxiety at which the 0.two percent lasting strain occurs may be established with enough precision by calculating the elastic extension of your gauge length underneath appropriate load and including thereto 0.
All spun cylinders and plugged cylinders has to be tested for leakage by fuel or air force soon after the bottom has been cleaned and is particularly cost-free from all dampness issue to the subsequent situations and constraints:
(two) A maker of a packaging subject matter to the necessities of this component is mostly answerable for compliance with the necessities of the element. Nevertheless, anyone who performs a purpose prescribed During this section shall conduct that operate in accordance with this particular component.
Cylinders need to be created utilizing devices and processes adequate to make certain Just about every cylinder generated conforms to the requirements of the subpart. No defect is acceptable that is probably going to weaken the concluded cylinder appreciably.
(iv) Long-lasting volumetric growth may not exceed 10 p.c of the whole volumetric expansion at examination pressure.
