ASME SA-789-2017 pdf download.SPECIFICATION FOR SEAMLESS AND WELDED FERRITIC/AUSTENITIC STAINLESS STEEL TUBING FOR GENERAL SERVICE.
3. Ordering Information 3.1 Orders for product under this specification should in- clude the following, as required, to describe the desired material adequately: 3.1.1 Quantity (feet, metres, or number of lengths), 3.1.2 Name of product (seamless or welded tubes), 3.1.3 Grade (see Table 1), 3.1.4 Size (outside diameter and nominal wall thickness), 3.1.5 Length (specific or random), 3.1.6 Optional requirements (for product analysis, see Sec- tion 8; for hydrostatic or nondestructive electric test, see Section 10), 3.1.7 Test report required (see the Inspection section of Specification A1016/A1016M), 3.1.8 Specification designation, and 3.1.9 Special requirements.
4. General Requirements 4.1 Product furnished under this specification shall conform to the applicable requirements of Specification A1016/ A1016M, unless otherwise provided herein.
5. Manufacture 5.1 The tubes shall be made by the seamless or welded process with no filler metal added.
6. Heat Treatment 6.1 All tubes shall be furnished in the heat-treated condition in accordance with the procedures shown in Table 2. For seamless tubes, as an alternate to final heat treatment in a continuous furnace or batch-type furnace, immediately follow- ing hot forming while the temperature of the tubes is not less than the specified minimum solution treatment temperature, tubes may be individually quenched in water or rapidly cooled by other means.
7. Chemical Composition 7.1 The steel shall conform to the chemical requirements prescribed in Table 1.
9. Mechanical Tests Required
9.1 Tension Tests—One tension test shall be made on a specimen for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes (see Note 2).
9.2 Flaring Test (for Seamless Tubes)—One test shall be made on specimens from one end of one tube from each lot (see Note 1) of finished tubes. The minimum expansion of the inside diameter shall be 10 %.
9.3 Flange Test (for Welded Tubes)—One test shall be made on specimens from one end ofone tube from each lot (see Note 1) of finished tubes.
9.4 Hardness Test—Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot (see Note 2).
9.5 When more than one heat is involved, the tension, flaring, flanging, and hardness test requirements shall apply to each heat.
9.6 Reverse Flattening Test—For welded tubes, one reverse flattening test shall be made on a specimen from each 1500 ft [450 m] of finished tubing.ASME SA-789 pdf download.
