(ii) Taper threads for being of size not lower than as specified for American Normal taper pipe threads.

(i) The remaining cylinders in Each and every ton has to be pressure tested by the proof tension, drinking water-jacket or immediate expansion examination strategy as prescribed in CGA C-one. The minimum amount exam tension needs to be maintained for the specific timeframe and the screening products needs to be calibrated as prescribed in CGA C-1.

A Actual physical exam have to be done to determine produce energy, tensile strength, and elongation as follows:

This exam can be used and have to be as needed by CGA Pamphlet C-3. The specimen need to be bent until the elongation with the outer floor, adjacent to the foundation of your weld, involving the frivolously scribed gage lines-a to b, is a minimum of 20 p.c, except this proportion could be decreased for steels having a tensile toughness in extra of 50,000 psi, as furnished in paragraph (k) of this section.

(i) If the selected cylinder passes the h2o-jacket or immediate enlargement exam, the remaining cylinders in Every lot needs to be strain tested with the proof strain h2o-jacket or direct enlargement test approach as prescribed in CGA C-1.

(ii) Getting a Accredited chemical analysis from the fabric or cylinder company for each melt, or Forged of material; or

(iii) The minimal take a look at strain should be preserved a minimum of thirty seconds and sufficiently more time to guarantee complete expansion. Any inner force used after warmth-treatment and before the Formal test may not exceed 90 percent in the examination stress.

(ii) In utilizing the “extension underneath load” strategy, the full pressure (or “extension below load”) corresponding to the stress at which the 0.2 per cent everlasting pressure occurs may be decided with ample precision by calculating the elastic extension from the gauge size less than suitable load and incorporating thereto 0.

(2) Warmth therapy just isn't necessary immediately after welding or brazing weldable low carbon parts to attachments, laid out in paragraph (file)(1) of this segment, of similar materials that have been Formerly welded or brazed to the very best or bottom of cylinders and thoroughly heat dealt with, furnished these kinds of subsequent welding or brazing isn't going to create a temperature in excess of four hundred °File in any Section of the top or bottom material.

(one) Each individual cylinder must be heated and held at the correct temperature for a minimum of one click here particular hour per inch of thickness depending on the most thickness of your cylinder after which you can quenched in a suitable liquid medium possessing a cooling rate not in surplus of 80 per cent of drinking water.

(iii) Straight threads, possessing a minimum of four engaged threads, to obtain restricted fit and calculated shear strength no less than ten instances the exam pressure on the container; gaskets required, satisfactory to forestall leakage.

(two) All seams with the sphere or cylinders need to be fusion welded. Seams needs to be with the butt or joggle butt variety and implies have to be delivered for carrying out entire penetration in the joint.

(six) Other markings are approved furnished These are built in low worry parts besides the aspect wall and therefore are not of the size and depth which will produce destructive pressure concentrations. This sort of marks might not conflict with any DOT needed markings.

S = PD / 4tE The place: S = wall pressure in kilos psi; P = take a look at force prescribed for drinking water jacket exam, i.e., at the very least two instances company pressure, in psig; D = outside diameter in inches; t = minimal wall thickness in inches; E = 0.
