(ii) Taper threads has to be of a duration not under that specified for American Conventional taper pipe threads.

The material needs to be discovered by any acceptable system apart from that plates and billets For warm-drawn cylinders must be marked with the heat number.

(2) Metallic attachments to cylinders have to have rounded or chamfered corners or has to be guarded in this kind of manner as to circumvent the probability of resulting in puncture or harm to other dangerous elements offers.

(2) Each opening within a spherical style of cylinder needs to be supplied with a fitting, manager, or pad of weldable metal securely attached into the cylinder by fusion welding.

(iii) For the purpose of pressure measurement, the First strain needs to be established whilst the specimen is less than a stress of twelve,000 psi along with the pressure indicator reading currently being established with the calculated corresponding strain.

(5) Every single new style and design and any considerable change to any suitable layout have to be certified for generation by tests prototype samples as follows:

Prior to the Preliminary shipment of any certain cylinder design and style, cyclic pressurization checks ought to are performed on at the least 3 consultant samples without the need of failure as follows:

A specimen need to be Reduce from a person cylinder of every large amount of 200 or much less, or even a welded take a look at plate. The welded exam plate have to be of among the list of heats from the large amount of 200 or considerably less which it signifies, in the exact same affliction and close to a similar thickness as being the cylinder wall apart from that it may not be of a lesser thickness than that expected for 1 / 4 size Charpy influence specimen. The weld have to be created by the exact same procedures and subjected to precisely the same warmth cure as the key weld within the cylinder.

Cylinders should be created employing devices and procedures suitable to ensure that Every single cylinder developed conforms to the requirements of the subpart. No defect is suitable that is probably going to weaken the concluded cylinder appreciably.

(two) In the event the porosity of each and every cylinder isn't acknowledged, a cylinder taken at random from lots of 200 or significantly less need to be examined for porosity. If your exam cylinder fails, Each individual cylinder in the great deal may be analyzed independently and people cylinders that move the examination are acceptable.
