11、equired 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, TMS-9516 for spot welding, etc.), unless otherwise specified. Weld symbols shall be in accordance with AN
12、SI/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 aluminum coating on the base
13、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 agreement. 4.1.2 Welds on fabr
14、icated 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 high-temperature paint confor
15、ming 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 Cubic Feet of air per Min
16、ute at 10 psig. 4.1.3 Weld filler metal: When welding exhaust tubing specified to this TMS, the weld filler metals specified in Figure 9 must be used, unless otherwise agreed upon by TDTC Engineering. 4.2 Workmanship 4.2.1 Dimensional Tolerances: Unless otherwise specified, the dimensional tolerance
17、s shown in Figures 1 through 11 of this specification 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 tubing shall
18、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 OD in be
19、nd 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 clean and
20、dry to the touch. When specified on the engineering drawing, the pipe(s) shall meet cleanliness requirements of TMS-9528, 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 indi
21、vidual 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 distortion, which reduce
22、s the consistency and accuracy of alignment at the tube ends. Use of cut and weld construction is NUMBER: TMS-1069 TITLE Steel Tubing for Engine Exhaust Systems REVISION 1308 This document is restricted and may not be sent outside Navistar, Inc. or reproduced without permission from Corporate Techni

24、r 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 deviations in construction and/
25、or material 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 longer used, and is superseded by Type VI below.
