10、(RPO) 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. Unless otherwise specified on the engineering drawing or purchase o
11、rder, the use of cut and weld construction shall require engineering approval. 4.1.2 In many cases, tubing used in the air intake and/or charge air systems are parts of the truck system which are required to meet Federal Noise Regulations (CFR Title 40, Section 205). All such applications shall be s
12、o indicated on the engineering drawing, and in these applications no deviations in construction and/or material shall be permitted without prior Engineering approval. 4.2 Material Requirements Unless otherwise specified on the engineering drawing, tubing supplied will meet the following requirements
13、: 4.2.1 Tubing Material: Shall be 3003, 6061, or 6063 aluminum per MPAPS C-10. 4.2.2 Temper: Unless engineering drawing specifies a particular temper, the tubing fabricator is responsible to select a temper suitable for fabrication which will allow the part(s) to meet the requirements of this specif
14、ication. 4.2.3 Tubing: Shall be seamless drawn, extruded, or welded tube at the option of the tubing fabricator. Tubing shall meet dimensional requirements of ANSI H35.2. 4.3 Dimensional Tolerances Unless otherwise specified, the dimensional tolerances shown in Figs. 2 thru 10 of this specification
15、shall apply to fabricated tube and tube assemblies, and the standard dimensional tolerances shown in the title block of the Navistar Engineering drawing are not applicable. 4.3.1 Tubing Wall Thickness Tubing wall thickness shall be specified on the engineering drawing. On existing drawings where thi
16、ckness is not specified, wall thickness shall be 0.083 inch. 4.4 Welding Required welding will be specified on the engineering drawing, and will comply with the American Welding Society standard AWS D1.2, Structural Welding Code for aluminum. Weld symbols shown on engineering drawings shall be in ac
17、cordance with AWS A2.4. Sizes of fillet/groove welds shown on the engineering drawing are minimum values. 4.4.1 Welds on Fabricated Tubing All welds on fabricated tube shall be neat and continuous with a minimum of flash and/or weld spatter. No weld spatter is permitted on flange sealing surfaces. 4
18、.4.2 Leakage Welded pipes/tubing shall show no leakage when pressure-tested at 25 psi (min) pressure.

Suppliers are required to assume all patent liability. 2017 by Navistar, Inc. APRIL 2017 Page 6 of 15 A.0 GENERAL INFORMATION (not a requ
41、irement) In order to obtain maximum life for pipe/tubing systems, to standardize designs and minimize costs, procedures described herein should be followed. This is particularly important with regard to bend radii and bend locations relative to each other. A.1 Design Procedure for Engineering Refere
42、nce A more effective and efficient method for the design of tubular products used in engine air/fluid systems has been developed. This method involves the simple use of a line drawing (center line) and XYZ coordinate table. An example of this method is shown in Figure 10. All radii are specified to
43、the center line of the pipe and all dimensions are given from the centerline and intersecting points. Provision of coordinates is via the XYZ-Tubing program available within the UNIGRAPHIC GRIP Program system. A.1.1 The use of this design method facilitates transfer of data from the engineering draw
44、ing to manufacturing operations because the data can be transferred directly into CNC controlled tube benders and/or coordinate measuring systems to permit manufacturing/inspection without the need for intermediate manufacturing drawings and/or checking/testing templates fixtures. The elimination of
45、 these steps improves efficiency/economy of operations. A.2 Manufacturing Methods and Design Procedure “Press“ (compression) bends generally have higher production rates and hence lower costs than “Mandrel“ bends and should be used whenever space permits their larger radii and lesser degree of bend.
46、 The supplier should be consulted for the preferred bend radius and availability of tooling before release of the drawing. A.2.1 Avoid bends which are too close together and the use of “bends-within-bends.“ They are difficult to fabricate, require non-standard tooling, and add significantly to the c
47、ost of the product. In many cases, rotating the bends (as shown in Fig. 6) will achieve the same result while permitting the use of standard tooling and reducing the costs. Use Chart #1, if necessary, to maintain adequate distance between bends as shown in Fig. 8. A.2.2 All radii on each pipe/tube s
48、hould be the same in order to minimize tool changes and set-up time. The exception to this rule is the special case where bends smaller than those shown in Chart #1 are necessary at one or two points and space permits the use of larger bend radii (as shown in Chart #1) at other points. The tubing fa
49、bricator/supplier should be consulted for guidance in these cases. A.2.3 Pipes used in pressurized fluid systems (coolant, charge air coolers, and air cleaners) are often connected to elastomeric hose(s) or use elastomeric connectors to reduce vibration. Beading at the end of the tube is used to provide adequate sealing and pull-off resistance. To reduce the transmission of vibrations and stresses between the engine and
