Joint deflection
Technical solutions
Joint deflection
PAM socket joints permit angular deflection. In addition to obvious advantages during laying and to accommodation of ground movements, the angular deflection allows negotiation of large radius bends without recourse to fittings, as well as a certain amount of route adjustment.
