(iv) Long term volumetric expansion may not exceed ten p.c of the whole volumetric enlargement at examination pressure.

Substance have to be recognized by any acceptable technique except that plates and billets For decent-drawn cylinders has to be marked with the warmth quantity.

Open up-hearth or electrical steel of uniform high quality should be utilised. A warmth of steel built less than desk 1 in this paragraph (b), Examine chemical Examination of that is marginally from the required assortment, is suitable, if satisfactory in all other respects, presented the tolerances demonstrated in desk two With this paragraph (b) aren't exceeded besides as accepted by the Associate Administrator. The subsequent chemical analyses are approved:

Standard taper pipe threads essential in all openings. The duration on the opening may not be a lot less than as specified for American Regular pipe threads; tapped to gauge; cleanse Slash, even, and without having checks.

A root bend take a look at specimen have to be removed from the cylinder or welded test plate which was employed for the tensile take a look at specified in paragraph (l)(one) of the part. The specimen have to be taken from throughout the circumferential seam and should be organized and examined in conformance with and need to satisfy the necessities of CGA C-3.

(2) If the porosity of each and every cylinder is not regarded, a cylinder taken at random from a lot of 200 or a lot less should be tested for porosity. If your take a look at cylinder fails, Just about every cylinder within the lot could possibly be tested individually and people cylinders that move the test are satisfactory.

(iii) For the purpose of pressure measurement, the initial strain have to be established when the specimen is below a stress of 12,000 psi as well as pressure indicator studying staying established at the calculated corresponding strain.

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

(1) The check have to be involving knife edges, wedge shaped, possessing a sixty° involved angle, and rounded in accordance with the following desk.
