ASTM A409/A409M-01(2005)

Standard Specification for Welded Large Diameter Austenitic Steel Pipe for Corrosive or High-Temperature Service

SCOPE
1.1 This specification covers straight seam or spiral seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered are NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thicknesses. Table X1.1 shows the wall thickness of Schedule 5S and 10S pipe. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.  
1.2 Several grades of alloy steel are covered as indicated in Table 1.  
1.3 Optional supplementary requirements are provided. 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.  
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
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."

4. General Requirements
4.1 Material furnished to this specification shall conform to the applicable requirements of the current edition of Specification
A 999/A 999M, unless otherwise provided herein.
5. Materials and Manufacture
5.1 If a specific type of melting is required by the purchaser it shall be stated on the order.
5.2 Welding:
5.2.1 The welds shall be made by the manual or automatic electric-welding process. For manual welding, the operator and
procedure shall be qualified in accordance with theASME Boiler and Pressure Vessel Code, Section IXr00001. Unless otherwise
specified on the purchase order, the pipe may be welded with or without filler metal when the automatic electric-welding process
is used.

5.2.2 The weld surface on either side of the weld may be flush with the base plate or may have a reasonably uniform crown,
not to exceed ⁄16 in. [2 mm].Any weld reinforcement may be removed at the manufacturer’s option or by agreement between the
manufacturer and purchaser. 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.
5.2.3 Weld defects, as determined by specified inspection requirements, shall be repaired by removal to sound metal and
rewelding.
5.3 Heat Treatment:
5.3.1 Except as provided in 5.3.2, all pipe shall be furnished in the heat-treated condition. The heat-treatment procedure shall
consist of heating the material to a minimum temperature of 1900°F [1040°C], except for S31254 and S30815 which shall be heat
treated to 2100°F [1150°C] and 1920°F [1050°C] respectively, S24565 which shall be heat treated in the range 2050°F [1120°C]
to 2140°F [1170°C], and N08367, which shall be heated to a minimum temperature of 2025°F [1107°C], all materials to be
followed by quenching in water or rapidly cooling by other means.
5.3.2 The purchase order shall specify one of the following conditions if the heat-treated condition specified in 5.3.1 is not
desired by the purchaser:
5.3.2.1 Afinal heat-treatment temperature under 1900°F [1040°C]. Each pipe supplied under this requirement shall be stenciled
with the final heat-treatment temperature in degrees Fahrenheit or degrees Celsius after the suffix “HT”. Controlled structural or
special service characteristics may be specified as a guide for the most suitable heat treatment.
5.3.2.2 No final heat treatment of pipe fabricated of plate, that has been solution heat treated at temperatures required by this
specification. Each pipe supplied under this requirement shall be stenciled with the suffix “HT-O”.
5.3.2.3 No final heat treatment of pipe fabricated of plate, that has not been solution heat treated. Each pipe supplied under this
requirement shall be stenciled with the suffix “HT-SO”.
5.4 A solution annealing temperature above 1950°F [1065°C] may impair the resistance to intergranular corrosion after
subsequent exposure to sensitizing conditions inTP321,TP347, andTP348.When specified by the purchaser, a lower temperature
stabilization or re-solution anneal shall be used subsequent to the initial high temperature solution anneal (see Supplementary
Requirement S5).
6. Chemical Composition
6.1 The steel shall conform to the chemical composition in Table 1.
6.2 When specified on the purchase order, a product analysis shall be supplied from one tube or coil of steel per heat. The
product analysis tolerance of Specification A 480/A 480M shall apply.
6.3 Unless otherwise specified in the purchase order, the chemical composition of the welding filler metal shall conform to the
requirements of the applicable AWS specification for the corresponding grade shown in Table 2. Grades with no filler metal
classification indicated shall be welded with filler metals producing deposited weld metal having a composition in accordance with
the chemical composition specified in Table 1. The method of analysis for nitrogen and cerium shall be a matter of agreement
between the purchaser and manufacturer. The purchaser may choose a higher-alloy filler metal when needed for corrosion
resistance.
7. Tensile Requirements
7.1 The tensile properties of the plate or sheet used in making the pipe shall conform to the requirements prescribed in Table
3. Certified mill test reports shall be submitted to the pipe manufacturer.
7.2 A transverse tension test taken across the welded joint of the finished pipe shall meet the same minimum tensile strength
requirements as the sheet or plate. The weld section on the tension specimen shall be in the same condition as the finished pipe
(with or without bead as specified).
8. Mechanical Tests Required
8.1 Tension Test—One transverse tension test of the weld shall be made on each lot (Note 2) of finished pipe.
NOTE 2—The term “lot” applies to each 200 ft [60 m] or less of pipe of the same NPS and wall thickness (or schedule number) which is produced
from the same heat of steel and subjected to the same finishing treatment in a continuous furnace. When final heat treatment is in a batch-type furnace,
the lot shall include only that pipe which is heat treated in the same furnace charge. When no heat treatment is performed following final forming
operations, the lot shall include each 200 ft [60 m] or less of pipe of the same NPS and wall thickness (or schedule number) which is produced from
the same heat of steel.
8.2 Transverse Guided-Bend Weld Test— One test (two specimens) of the weld shall be made on each lot (Note 2) of finished
pipe.
8.3 Pressure or Nondestructive Electric Test—Each length of pipe shall be subjected to a pressure test or a nondestructive
electric test as prescribed in Section 5.
9. Permissible Variations in Wall Thickness
9.1 The minimum wall thickness at any point shall not be more than 0.018 in. [0.46 mm] under the specified wall thickness.
