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 shown on engineering drawings shall be in accordance with ANSI/AWS A2.4. Sizes of fillet/groove welds shown on the engineering dr

12、awing are minimum values. When brazing is specified on the drawing (e.g., for attaching end fittings), welding may not be substituted without prior approval from Engineering. 4.1.1 External weld seams on aluminized tubing shall be metalized with an aluminum coating. The thickness of the remetalized

13、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 shall be 0.00025 inch as measured microscopically on cross sections taken perpendicular to the weld seam. Other methods of

14、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 flange sealing surfaces. 4.1.2.1 Aluminized tubing: All weld areas on fabricated aluminized tubing, as well as uncoated atta

15、chments, shall be painted with an aluminum-colored paint after welding. If parts will be exposed to higher temperatures, aluminum-colored paint shall conform to TMS-9015 Type I. 4.1.2.2 Leakage: Welds on fabricated pipes/tubing shall show no leakage when pressure-tested at 25 psi (min) pressure. 4.2

16、 Workmanship Unless otherwise specified, end points are to be maintained within 0.25 inch of the basic location. Intermediate points shall be located within 0.25 inch. Straightness shall be within 0.25 inch. Ends shall be free of burrs. Bend radii to be within 0.25 inch See Figure 3. 4.2.1 Dimension

17、al Tolerances: Unless otherwise specified, the dimensional tolerances shown in Figures 1 through 15 of this specification shall apply, and the standard dimensional tolerances shown in the title block of the Navistar Engineering drawing are not applicable. Dimensioning and tolerancing shown in these

18、figures is in accordance with ASME Y14.5M-1994. Cylindricity of tubing shall not exceed 1.5% of the nominal tube diameter.

33、uct supplied to the requirements of this specification shall be free of rust, stains, oil, dirt, metal chips, grease, weld spatter, etc., and shall be clean and dry to the touch. 5.1 Cleanliness of CAC, Coolant, and Radiator Pipes CAC, coolant, and radiator pipes should be clean when installed on th

34、e vehicle, to avoid introducing dirt or other contaminants into the engine cooling or air systems. To assure that sufficient cleaning has been performed to provide the required level of cleanliness, a specific test method, describing maximum amount (weight) of debris and maximum allowable particle s

35、izes, may be established as a requirement for the CAC pipes by specifying on the drawing, “Cleanliness per MPAPS F-2.” After the required cleaning operation has been performed by the pipe/tube supplier, it is essential that the pipes be protected from any re-contamination in transit and/or storage.

36、This protection may be achieved by capping the ends of the pipes, or otherwise protecting them from contamination in transit and storage. CAC pipes provided for Service Parts are generally required to be individually end-capped. 5.2 KCC - Key Control Characteristics - General Application One KCC val

37、ue (minimum) should be designated on each new drawing released by Engineering in accordance with provisions of Engineering Design Standard A-16. Engineering should consult with the supplier to assure selection of appropriate KCC values prior to release of the Engineering drawing. KCC values shall be

38、 incorporated in the Quality Control Plan for each part as features for which management by statistical process control is mandatory. 5.2.1 KCC Requirements Applicable to Radiator and CAC Pipes Engineering has designated specific dimensions as KCC features for all radiator (water) and charge air coo

39、ler (CAC) pipes. Unless specific exception is noted on the engineering drawing and/or purchase order, the following characteristics are designated as KCC features: 1. O.D. of the pipe within 1.5 inches of the pipe ends. 2. Height of the sealing bead. 6.0 SOURCE APPROVAL AND QUALITY CONTROL 6.1 Suppl
