Mitre bends
EN 13480-3:2012, 6.3 may be used for the design of mitre bends for aluminium and aluminium alloys
The method outlined in Formulae (6.5-1) to (6.5-4) can be applied to multiple mitre bends for aluminum and aluminum alloys, as illustrated in Figure 6.5-1, with a maximum angle of Θ set at 22.5° It is important to note that the pressure limit specified in EN 13480-3:2012, section 6.3.1, does not apply to this method.
Current data indicates that experiences are available for pressures up to 63 bar for time-independent design stresses While this does not restrict the calculation of mitre bends for higher pressures, it highlights the reference pressure at which mitre bends made from aluminum and aluminum alloys, designed according to established rules, can operate safely.

Designing with transition joints
Design considerations
During the design analysis, it is essential to consider transition joints as integral elements of the piping system Designers must account for all potential loadings that may occur under the specified design conditions.
Location of transition joints
A transition joint must be strategically placed to avoid excessive loading effects, including tensile and shear forces, as well as bending and torsional moments When applicable, the fabricator of the transition joint should supply allowable load specifications or guidelines for evaluating pressure and combined external loads.
In general, positioning transition joints directly against piping elbows shall as far as possible be avoided.
Requirements for transition joints
Transition joints shall meet the requirements of Annex B
Port-hole-extruded tubes conforming to the EN 755 series can be utilized for sizes up to DN 25 with a joint efficiency of 0.7 However, if a combined pressure-leak test is conducted along the entire length of the tubes, the joint efficiency can be increased to a factor of 1 When performed by the tube manufacturer, the test pressure must be specified as e px.
P e (6.8-1) by the piping manufacturer, the test pressure shall be
Before integrating into the piping system, a combined pressure-leak test must be conducted to achieve a joint efficiency factor of 1, utilizing either helium or a helium-containing gas mixture based on the specific application This test is not a substitute for the pressure test outlined in sections 9.1 and 9.2.
Design by Analysis (DBA) according to EN 13445-3:2009 may be applied, using the method based on stress categories only.
