SAE AS 5959B:2013 pdf free.Axially Swaged Fittings,Installation and Inspection Procedure
Prior to the listing of new gaging and tooling numbers in this procedure, the fttingtooling system supplier shall demonstrate the interchangeability/capability by assembling and gaging two sample fttings of each size of each manufacturer listed in the PRI-QPL 5958. The assembled fittings shall be tested to and pass the AS5958 impulse test requirements. Potential suppliers shall submit a plan to demonstrate interchangeability/capability to the Performance Review Institute (PRI), G-3 Fluid Distribution, Qualified Products Group (QPG), at PRI, 161 Thorn Hill Rd, Warrendale, PA 15086-7527. The QPG will grant approval for the suppliers numbers and name be added for the applicable tools or gages after demonstrating interchangeability/capability.
At least one pair of marks, (positioning marks and inspection marks) as shown in Figure 1, shall be pre-applied with the given dimensions from Table 1 to each prepared tube end prior to fitting installation. A suitable permanent method such as ink stamp, anodize, or electro-etch, etc., may be used. Should the tube ends be unmarked, the appropriate marks shall be applied using tube marking gage as shown in Figures 2A and 2B, and using a suitable permanent ink felt tipped pen such as Sanford Sharpie TEC (Trace Element Certified) marker no.13401.
NOTE 1: Due to the possibility of contaminating titanium tubing, inks which contain lead, 25 ppm maximum, or free halogens, 225 ppm combined maximum, should not be used for marking，
NOTE 2: See Table 2 for suppliers of marking gages.
Locate the edge of the unswaged ftting “ring” over the positioning mark as shown in Figures 3A and 3B. The length of the positioning mark is the amount of positioning tolerance allowed. The edge of the ftting“ring” may be anywhere along the iength of the positioning mark.
In the case of unions, the tube insertion allowance is shared by each leg of the union. If one tube end is inserted to maximum depth, then the opposite tube end can only be inserted to a minimum depth as shown in Figure 5. This shared insertion condition is only applicable to unions, which have a through bore to allow placement onto cut lines during repair.
NOTE: Under maximum insertion conditions, it will not be possible to see the Inspection mark until after swaging.SAE AS 5959B pdf free download.
