METHOD OF FILLING A CASING

摘要

Foam filling a cavity in a joint between insulated pipe lengths by wrapping a fibre reinforced plastic mold sheet around the cavity or applying a casing around the cavity, with a securing element supplied on the mold sheet to resist separating movements of the ends of the mold sheet or one or more flexible tensile members wrapped around the casing, to resist ballooning of the casing on expansion of a foam filling introduced into the mold or into the casing.
