Annex B
B.1 General
B.2 Calculation of depth of engagement
B.2.1 Depth of engagement, m, is calculated by
B.2.2 Poisson contraction — shortening of length when pressurized:
B.2.3 Temperature contraction — shortening due to drop in temperature:
B.2.4 Angular deflection —retraction of one side of the spigot due to angular deflection of the spigot within the socket:
B.2.5 Chamfer length — length of chamfer c, in millimetres, shall be included in the available depth of engagement, as per the manufacturer’s specification.
B.2.6 Safety allowance S — for construction error ms.
B.2.7 Example — the above allowances for a 6 m DN 315 pipe total.
