11、IREMENTS 4.1 Welding Required welding will be specified on the engineering drawing, and will be consistent with the applicable 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 shal

12、l be in accordance with ANSI/AWS A2.4. Sizes of fillet/groove welds shown on the engineering drawing are minimum values. 4.1.1 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 alu

13、minum coating on the base metal to provide equivalent corrosion resistance. The minimum thickness of the remetalized layer shall 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 agre

14、ement. 4.1.2 Welds on fabricated tube shall be continuous with a minimum of weld spatter. No weld spatter is permitted on flange 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 hig

15、h-temperature paint conforming to the requirements of TMS-9015, Type 1. 4.1.2.2 Leakage: Welds on fabricated pipes/tubing shall show 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

16、 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 filler 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 speci

17、fied, the dimensional tolerances shown in Figures 1 through 11 shall apply, and the standard dimensional tolerances shown in the 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 tubi

18、ng shall not exceed 1.5% of the nominal tube diameter. For parts specified to have tube ends sized, cylindricity at the ends shall 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

19、 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 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 c

20、lean and dry to the touch. When specified on the engineering drawing, the pipe(s) shall meet the applicable cleanliness requirements 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 prov

21、ided for service, to individual users or to Parts Storage facilities, are generally required to be individually end-capped. 4.3 Construction Engineering design is generally based upon single piece construction, rather than cut and weld construction. The welding process adds extra cost and introduces

22、 distortion, which reduces the consistency and accuracy of alignment at the tube ends. Use of cut and weld construction is NUMBER: MPAPS F-1069 TITLE Steel Tubing for Engine Exhaust Systems REVISION 1410 This document is restricted and may not be sent outside Navistar, Inc. or reproduced without per

24、any cases, tubing and any other parts of the exhaust systems that gas passes through are parts of the truck system which are required to meet Federal Noise Regulations (CFR Title 40, Section 205). All such applications shall be so indicated on the engineering drawing, and in these applications no de

25、viations in construction and/or material outside the allowance of Section 4.3 shall be permitted without prior Engineering approval. 4.4 Material And Finish Unless otherwise specified, tubing supplied will meet requirements for the Type as indicted below. 4.4.1 Tubing Types: Type I - This type is no
