(ii) Taper threads must be of a size not less than as specified for American Normal taper pipe threads.

(1) Each and every cylinder has to be uniformly and properly heat handled just before exam through the applicable process shown in table 1 of appendix A to this aspect. Heat remedy must be achieved In spite of everything forming and welding functions, apart from that when brazed joints are used, heat remedy ought to comply with any forming and welding functions, but can be accomplished right before, all through or following the brazing functions (see paragraph (m) of this section for weld repairs).

(i) The remaining cylinders in the ton should be analyzed from the proof tension, water-jacket, or immediate expansion take a look at method as prescribed in CGA C-1. The least test force needs to be taken care of for the precise timeframe and also the screening gear needs to be calibrated as prescribed in CGA C-1.

(i) The remaining cylinders in Each and every good deal has to be analyzed from the evidence pressure drinking water-jacket or immediate enlargement test strategy as prescribed in CGA C-1. The minimum amount take a look at pressure has to be taken care of for the precise timeframe along with the testing machines should be calibrated as prescribed in CGA C-1.

(i) Least thickness of heads and bottoms should be not less than 90 per cent on the essential thickness of the facet wall.

You might be using a browser that may not supported by Fb, so we've redirected you to a simpler Variation to provde the finest experience.

(two) When the cylinders are heat taken care of in the continual furnace, two rigidity specimens and 3 Charpy impression specimens needs to be analyzed from on the list of cylinders or a check ring from Each and every four hrs or considerably less of production. Nevertheless, in no case may well a exam great deal determined by this generation period of time exceed two hundred cylinders.

(two) Just about every opening while in the cylinder, except Individuals for security gadgets, should be supplied having a fitting manager, or pad, securely hooked up on the cylinder by welding or by threads. If threads are utilised they must adjust to the subsequent:

S = Mc/I (iii) To determine the utmost longitudinal tensile pressure as a consequence of hydrostatic exam pressure, the following formulation has to be utilised:

(ii) The filling material must be uniform in quality and freed from voids, apart from that a very well drilled in the filling content beneath the valve is authorized In the event the effectively is filled with a cloth of these kinds of style the functions of the filling substance will not be impaired;

(3) For filling that is definitely molded and dried prior situs bar178 to insertion in cylinders, porosity take a look at may very well be designed over a sample block taken at random from product for use.

Each cylinder, in advance of insulating and jacketing, will have to correctly withstand a pressure test as follows:

(ii) Just one cylinder must be selected from Just about every ton and become hydrostatically force examined to destruction. If this cylinder bursts beneath five (5) instances the provider tension, then two extra cylinders from the exact same good deal since the Formerly tested cylinder should be picked and subjected to this exam.

(two) When the porosity of each cylinder isn't identified, a cylinder taken at random from plenty of two hundred or fewer need to be examined for porosity. When the exam cylinder fails, Each individual cylinder from the good deal might be analyzed individually and people cylinders that pass the exam are satisfactory.
