| MACHINING ALLOWANCES FOR CDS TUBING FROM WAREHOUSE STOCK | |
|---|---|
| The following procedure may be used to determine the proper warehouse stock size (O.D. and wall thickness) of Cold Drawn Seamless or Butt Weld Steel Tubing with sufficient allowance for machining, based on chucking true to O.D. | |
| A = Machined O.D. (Maximum) | |
| B = Machining allowance, O.D. or I.D. | Tolerance |
| Under 1-1/2" O.D. | .020" |
| 1-1/2” to 3" Excl. | .040" |
| 3” to 5-1/2" Excl. | .060" |
| 5-1/2” to 8" Excl. | .080" |
| C = Camber in length of part, ratio per foot. | Tolerance |
| Under 5" O.D. | .020" |
| 5" to 8" Excl. | .030" |
| 8" to 10-3/4" | .040" |
| D = Machined I.D. (Minimum) | |
| E = Outside Diameter Tolerances | |
| F = Percent of Wall Thickness | |
| Calculated O.D. = A + B + C | |
| Stock Size O.D. –When the calculated O.D. is not shown as available in the stock list, use the stock size O.D. listed which is next larger than the calculated O.D. | |
| Calculated I.D. = D - ( B + C ) | |
| Calculated Wall Thickness = [(Stock Size O.D. + E - Calculated I.D.)(1.00 + F)]/2 |
|
| Stock Size Wall Thickness – When the calculated wall thickness is not shown as available in the stock size O.D. above, use the stock size wall thickness listed, which is next heavier. | |
| Notes: If the machined part is less than 4" long, or the maximum machined O.D. and minimum machined I.D. is within 4" of the chuck, camber may be ignored. Also, the formula assumes that tolerances, surface defects, eccentricity, and camber are all at the permissible maximum at the same time. Since this condition is extremely unlikely, a stock size slightly under either the calculated O.D. or wall may sometimes be used to advantage with the risk offset by the savings in material cost. | |

| Rockwell Hardness | B65 maximum |
| * For tubes with OD of 3/8 inch and/or wall thickness of 0.035, a minimum elongation of 30 percent is permitted. | |
| FLATTENING TEST |
|---|
| A section at least three inches in length shall be taken from every 1500 feet or less of finished tubing and shall be flattened between parallel plates to three times the wall thickness of the tube. The weld shall be placed at a point of 90 degrees from the direction of applied force. Any cracking or flaws revealed by this test shall be cause for rejection. Superficial ruptures resulting from minor surface imperfections shall not be cause for rejection. |
| Reverse Flattening Test |
|---|
| A section at least four inches in length shall be taken from every 1500 feet or less of finished tubing and split longitudinally 90 degrees on each side of the weld and the sample opened and flattened. There shall be no evidence of cracks or lack of penetration or overlaps resulting from flash removal in the weld. |
| Expansion Test |
|---|
| A suitable specimen shall be taken from each 1500 feet or less of tubing and subjected to an expansion over a plug. The outside diameter must be expanded 25 percent throughout a length equal to the outside diameter of the tubing or one inch, whichever is greater. There shall be no evidence of cracking in this test. |
| PRESSURE AND/OR ELECTRICAL TEST |
|---|
| Tubing supplied under this specification shall have been hydrostatically tested at a fiber stress of 20,000 psi or at an actual pressure of 5,000 psi, whichever is less, based on the applicable minimum wall, or tested by use of a nondestructive electrical test approved by purchaser. |
| MANUFACTURING QUALITY |
|---|
| The tubing shall be normalized and followed by a cold working operation. The cold working shall result in minimum reduction of areas of 15 percent of which at least 8 percent shall be reduction of wall thickness. After cold working, the tubing shall be annealed in such a manner that the resultant product will meet all requirements of this specification. |

| FLATTENING TEST | |
|---|---|
| A three inch section cut from the tubing shall not crack or show any flaws when flattened between parallel plates to three times the wall thickness of the tube. |
| Expansion Test | |
|---|---|
| A section of tube approximately four inches in length with the ends burred shall withstand being expanded at one end over a polished tapered mandrel having an included angle of 60 degrees until the actual average inside diameter is increased 30 percent. The expansion test shall be made in a die in order to restrict the expansion of 30 percent. The axis of the mandrel should be paralled to the axis of the tube during the expansion tests. |
| HYDROSTATIC TEST | |
|---|---|
| Tubing supplied under this specification shall have been tested at not less than 1,000 lbs. hydrostatic pressure or higher in case working conditions require. |
| MANUFACTURING QUALITY | |
|---|---|
| Tubing shall be free from defects and in accordance with the best commercial practice. |
