Abstract

Method of insulating pipe details, such as pipe branches. A continous insulating layer is obtained around the pipe branch by enclosing the pipe branch (15, 16) in a mould which sealingly surrounds the branching point and contains a thermoplastic material, whereafter the mould is rotated so that the thermoplastic material forms a continous layer (17, 18) around the branching point. The closed space between this layer and the pipes (15, 16) is finally filled with an insulating material, for example, a foam plastic.
