ASTM A409 PDF

Historical Version s - view previous versions of standard. More A This guide covers standard specification for straight seam or spinal seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. Several grades of alloy steel shall be covered and shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, titanium, columbium, cerium, and other elements. The chemical composition of the welding filler metal shall also conform to the requirements of the applicable AWS specification for the corresponding grade.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Scope 1. Table X1. These call for additional tests to be made, and when desired shall be stated in the order, together with the number of such tests required.

Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. NOTE 1—The dimensionless designator NPS nominal pipe size has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size.

Referenced Documents 2. Ordering Information 3. Current edition approved Sept. Published October Originally approved in General Requirements 4. Materials and Manufacture 5. The contour of the reinforcement should be reasonably smooth and free from irregularities.

The weld metal shall be fused uniformly into the plate surface. No concavity of contour is permitted unless the resulting thickness of weld metal is equal to or greater than the minimum thickness of the adjacent base metal.

TPL S 0. TPCb S 0. TP S 0. S 0. N 0. B The titanium content shall be not less than 5 times the carbon content and not more than 0. C The columbium plus tantalum content shall be not less than 10 times the carbon content and not more than 1. D The columbium plus tantalum content shall be not less than 10 times the carbon content and not more than 1. The tantalum content shall be 0. Chemical Composition 6.

The method of analysis for nitrogen and cerium shall be a matter of agreement between the purchaser and manufacturer. Tensile Requirements 7. Mechanical Tests Required 8.

UNS Class. Permissible Variations in Wall Thickness 9. This tolerance is slightly more than commercial tolerances on sheet and plate to allow for possible loss of thickness caused by manufacturing operations.

Permissible Variations in Dimensions Outside diameter tolerances closer than shown above may be obtained by agreement between the pipe manufacturer and purchaser. Lengths For outside diameters of over NPS 22, the minimum length will be 5 ft Note 3. The corresponding metric value s shall be agreed upon between the manufacturer and the purchaser.

Workmanship, Finish, and Appearance Areas shall be suitably prepared for welding with tightly closed defects removed by grinding. Open, clean defects, such as pits or impressions, may require no preparation. The purchaser may request that a passivating treatment be applied. Test Specimens The run-off plate material shall be of the same heat, preferably shear croppings from the same plate.

Transverse Guided-Bend Weld Tests One shall be subject to a face guided-bend test and the second to a root guided-bend test. S 94 [] 44 []. S 87 [] 45 []. S 75 [] 30 []. S 80 [] 35 []. S [] 60 []. S 95 [] 48 []. N t 0. Pressure Tests The weld and weld area shall be inspected with the use of soap solution or any other prepared solution which will detect the leakage of air or gas from the inside. These methods shall be ca- pable of detecting both surface and subsurface defects.

Inspection The inspector shall have entry at all times. Product Marking Additional marking requirements for heat treatment are de- scribed in Supplementary Requirement S2. The purchaser may specify a different frequency of test or analysis than is provided in the supplementary requirement. Product Analysis S1. The drillings for product analysis may be taken from shear crop or test speci- mens. The results of product analysis shall conform to the requirements in Table 1 and shall be reported to the purchaser.

Radiographic Examination S2. Corrosion Requirements S3. All other nonmolybdenum-bearing types, except for Grade TP, shown in Table 1 shall be tested in the annealed and unsensi- tized condition and the rate of penetration shall not exceed 0. The condition of the test specimen is as follows: All molybdenum-bearing types shown in Table 1 shall be tested in the annealed and unsensitized condition. All specimens shall meet the requirements of the prescribed bend test.

Ferrite Control of Weld Deposits S4.
