ABSTRACT OF THE DISCLOSURE A system for pipeline joint coating and insulation in which the exposed field-joint of thermally insulated pipeline, following welding of the joint, is insulated by applying a clam-shell mould over the exposed welded joint, suitably venting the mould, and injecting a fast-setting organic foamed insulation into the annular cavity formed between the exterior of the pipeline and the mould, thereby filling the cavity, such that the organic insulation is compatible with and bondable to the exposed ends of the shop-applied thermal insulation encasing the pipeline sections interrupted by the joint, removing the mould and wrapping the solidified insulation thus formed with suitable wrapping, thereby to form a homogeneous water-tight and thermally-insulating joint section having a diameter uniform with the shop-applied insulation.
