DECEMBER 2009 Page 2 of 13 4.0 GENERAL REQUIREMENTS 4.1 Welding Required welds will be specified on the engine
12、ering drawing. 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 External weld seams on aluminized tubing shall be metalized with an aluminum coating. The thickness of the remetalized layer should be equiva
13、lent 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 measurement of the met
14、alized 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, along with uncoated attachments, shall be pain
15、ted with an aluminum-colored paint conforming to the requirements of Grade -33 per CEMS G-5, Part III. 4.1.2.2 Leakage: Welds on fabricated pipes/tubing shall show no leakage when pressure-tested at 25 psi (minimum) pressure. 4.1.3 Weld filler metal: When welding exhaust tubing specified to this TMS
16、, 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 tolerances shown in Figures 1 through 10 of this specification shall apply, and the standard dimens
17、ional 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 not exceed 1.5% of the nominal tube diameter. For parts specified to have tube ends sized,
18、 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 bend areas shall conform to limits shown in chart #1 and Fig. 1. 4.2.4 Quality: There shall
19、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 dry to the touch. When specified on the engineering drawing, the pipe(s) shall meet cleanl
20、iness 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 individual users or to Parts Storage facilities, are generally required to be individually end
21、-capped.

DECEMBER 2009 Page 3 of 13 4.3 Construction Engineering design is generally based upon single piece construction, rather than c
23、ut and weld construction. The welding process adds extra cost and introduces distortion, which reduces the consistency and accuracy of alignment at the tube ends. Unless otherwise specified on the engineering drawing or purchase order, the use of cut and weld construction shall require engineering a
24、pproval (see Section A.4 for additional discussion). 4.3.1 In many 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 indic
25、ated on the engineering drawing, and in these applications no deviations in construction and/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 Type I Alum
