11、 AWS or Navistar welding standard (e.g., AWS D1.1 for steel, AWS D1.6 for stainless steel, MPAPS P-9516 for spot welding, etc.), unless otherwise specified. Weld symbols shall be in accordance with ANSI/AWS A2.4. Sizes of fillet/groove welds shown on the engineering drawing are minimum values. 4.1.1
12、 External weld seams on aluminized tubing shall be metalized with an aluminum coating. The thickness of the remetalized layer should be equivalent to the thickness of the aluminum coating on the base metal to provide equivalent corrosion resistance. The minimum thickness of the remetalized layer sha
13、ll be 0.00025 inch as measured microscopically on cross sections taken perpendicular to the weld seam. Other methods of measurement of the metalized layer may be used by agreement. 4.1.2 Welds on fabricated tube shall be continuous with a minimum of weld spatter. No weld spatter is permitted on flan
14、ge sealing surfaces. 4.1.2.1 Aluminized tubing: All weld areas on fabricated aluminized tubing, along with uncoated attachments, shall be painted with an aluminum-colored high-temperature paint conforming to the requirements of MPAPS G-9015,. 4.1.2.2 Leakage: Welds on fabricated pipes/tubing shall s
15、how no leakage when pressure-tested at 25 psi (minimum) pressure. Welds on fabricated pipes/tubing bellows assemblies maximum leakage rate shall be less than 0.03 Standard Cubic Feet of air per Minute at 10 psig. 4.1.3 Weld filler metal: When welding exhaust tubing specified to this spec, the weld f
16、iller metals specified in Figure 9 must be used, unless otherwise agreed upon by NAVISTAR Engineering. 4.2 Workmanship 4.2.1 Dimensional Tolerances: Unless otherwise specified, the dimensional tolerances shown in Figures 1 through 11 shall apply, and the standard dimensional tolerances shown in the
17、title block of the engineering drawing are not applicable. Dimensioning and tolerancing shown in these figures is in accordance with ASME Y14.5M-1994. Cylindricity of tubing shall not exceed 1.5% of the nominal tube diameter. For parts specified to have tube ends sized, cylindricity at the ends shal
18、l be within the indicated diameter tolerance as shown in Figures 2 thru 7. 4.2.2 Wrinkles in or adjacent to bends shall not exceed 0.040 inch depth. 4.2.3 Reduction of the OD in bend areas shall conform to limits shown in chart #1 and Fig. 1. 4.2.4 Quality: There shall be no severe scratches or tool
19、 marks on the pipe/tube. All product supplied to the requirements of this specification shall be free of rust, stains, oil, dirt, metal chips, grease, etc., and shall be clean and dry to the touch. When specified on the engineering drawing, the pipe(s) shall meet the applicable cleanliness requireme
20、nts of MPAPS F-2, and when so specified, the ends of the pipe shall be capped, or otherwise protected so as to prevent contamination in shipment and/or storage. Parts provided for service, to individual users or to Parts Storage facilities, are generally required to be individually end-capped. 4.3 C
21、onstruction Engineering design is generally based upon single piece construction, rather than cut and weld construction. The welding process adds extra cost and introduces distortion, which reduces the consistency and accuracy of alignment at the tube ends. Use of cut and weld construction is permis
