(Specification)Standard Specification for Electric Fusion Welded Nickel and Nickel Alloy Pipe
Standard Specification for Electric Fusion Welded Nickel and Nickel Alloy Pipe
ABSTRACT
This specification covers electric fusion welded pipe suitable for high-temperature or corrosive service. The pipes are designated into five classes namely Class 1, Class 2, Class 3, Class 4 and Class 5, according to how they are to be welded. The joints shall be full penetration double-welded or single-welded butt joints employing fusion welding processes. The furnished pipe shall undergo heat treatment and a chemical analysis shall be employed for both plate and weld. Each pipe shall be subjected to transverse tension test, transverse guided weld bend test and hydrostatic pressure test.
SCOPE
1.1 This specification covers electric fusion welded pipe suitable for high-temperature or corrosive service as listed in Table 1. (Although no restrictions are placed on the sizes of pipe that may be furnished under this specification, commercial practice is commonly limited to sizes not less than 8 in. (203 mm) nominal diameter.)
1.2 Five classes of pipe are covered as follows:
1.2.1 Class 1—Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
1.2.2 Class 2—Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
1.2.3 Class 3—Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.
1.2.4 Class 4—Same as Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal.
1.2.5 Class 5—Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

5. Materials and Manufacture
4.1
5.1 Materials—The plate material shall conform to the requirements of Specification B463—The plate material shall conform
to the requirements of the appropriate raw material specification listed in 2.1.
4.2Manufacture
5.2 Welding:
4.2.1The joints shall be double-welded, full-penetration welds made in accordance with procedures and by operators qualified
in accordance with the ASME Boiler and Pressure Vessel Code, Section IX.
4.2.2The welds shall be made either manually or automatically by an electric process involving the deposition of filler metal.
4.2.3The weld surface on either side of the weld shall be flush with the base plate or shall have a reasonably uniform crown,
not to exceed ⁄8
5.2.1 The joints shall be full penetration double-welded or single-welded butt joints employing fusion welding processes as
defined under “Definitions,” ASME Boiler and Pressure Vessel Code, Section IX. This specification makes no provision for any
difference in weld quality requirements regardless of the weld joint type employed (single or double) in making the weld. Where
backing rings or strips are employed, the ring or strip material shall be of the same P-number (Table QW-422 of Section IX) as
the plate being joined. Backing rings or strips shall be completely removed after welding, prior to any required radiography, and
the exposed weld surface shall be examined visually for conformance to the requirements of 5.2.3. Welds made by procedures
employing backing strips or rings which remain in place are prohibited. Welding procedures and welding operators shall be
qualified in accordance with ASME Boiler and Pressure Vessel Code, Section IX.
5.2.2 Except as provided in 5.2.2.1 and 5.2.2.2, welds shall be made in their entirety by processes involving the deposition of
filler metal.
5.2.2.1 For Class 4 pipe employing multiple passes, the root-pass may be completed without the addition of filler metal.
5.2.2.2 For Class 4 pipe, the weld surface exposed inside the pipe may result from a single pass made from the inside of the
pipe without the addition of filler metal.
5.2.2.3 All single-welded pipe shall be completely radiographed
5.2.3 The weld surface on either side of the weld shall be flush with the base plate or shall have a reasonably uniform crown,
not to exceed ⁄8 in. (3.2 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 shall be reasonably smooth and free of irregularities. The
deposited 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.
45.2.4 Weld defects shall be repaired by removal to sound metal and rewelding. Subsequent heat treatment and inspection (that
is, visual, radiographic and dye penetrant) shall be as required on the original welds.
4.35.3 Heat Treatment—TheproductofUNSN08020alloyshallbefurnishedinthestabilized-annealedcondition.Theproduct
of UNS N08026 alloy shall be furnished in the solution-annealed condition. The product of UNS N08024 alloy shall be furnished
in the annealed condition.
NOTE1—The recommended annealing temperatures all followed by quenching in water or rapidly cooling by other means are as follows: 1700 to
1850°F (927 to 1010°C) for UNS N08020, 2050 to 2200°F (1121 to 1204°C) for UNS N08026, and 1925 to 1975°F (1052 to 1079°C) for UNS N08024.
5.Chemical Composition
5.1The chemical composition of the pipe shall conform to the requirements in :
5.3.1 The pipe furnished under this specification, shall be heat treated in accordance with Table 1of Specification B463.
5.2For UNS N08020 pipe, the alloy content of the deposited weld metal shall conform to that required for the plate or the
welding electrodes as shown in Specification AWS A5.4 for E-320, or E-320LR and in Specification AWS 5.9 for ER-320 or
ER-320LR. For UNS N08026, the alloy content of the deposited weld metal shall conform to that required for the plate or the
B 474 – 03 (2009)
welding electrodes as shown in Specification AWS A5.11 for E-Ni-Cr-Mo-3 and in Specification AWS 5.14 for Er-Cr-Ni-Mo-3.
For UNS N08024, the alloy content of the deposited weld metal shall conform to that required for the plate.
5.3If product analysis is made of the plate or weld metal by the purchaser, the chemical composition thus determined shall
conform to the requirements specified in 5.1 and 5.2 subject to the permissible tolerances in Table 2 of Specification B463. . See
Table 1 for recommended practice.
5.3.2 The purchase order shall specify one of the following conditions if the heat-treated condition specified by Table 1 is not
desired by the purchaser.
