6、echanical Domain decided to publish this document in the form of a Technical Report of type 2 in order to facilitate the updating of this document. Page 4 TR 4815:11-2015 (E) 1 Scope This Technical Report gives recommendations for the assembly of pipe couplings with swivel flanges in heat resisting
7、steel or nickel alloy, inch series, for aerospace applications. This Technical Report is applicable to a welded junction of in heat resisting steel tubes or nickel alloy tube dimensioned for inch series. The assembly of pipe couplings with loose flanges and seals shown in this Technical Report is us
8、ed to: a maximum temperature of 225 C or 600 C (the maximum temperature depends on the seal in the assembly); a nominal pressure up to 21 000 kPa (210 bar) (the nominal pressure depends on the seal technology, tube material and wall thickness in the assembly). 2 Normative references The following do
