    • A method for forming a field joints between sections of coated or insulated pipe which are to be welded together and incorporated into an undersea pipeline for carrying single or multi-phase fluids such as oil, gas and water. The method includes the application of a liquid epoxy layer which overlaps a lip of the factory-applied FBE coating protruding beyond a chamfered end of the factory-applied insulation layer, and which may be applied over the entire weld joint area. The liquid epoxy layer is partially cured by application of heat, and a layer of powdered adhesive is applied onto the partially cured liquid epoxy layer. The adhesive is subsequently sintered and activated by application of heat to its outer surface. The outer surfaces of the adhesive layer and the chamfers are then preheated and the thermal joint insulation is injection molded over the entire joint area. Throughout the entire method the temperature of the factory-applied FBE coating is maintained below its glass transition temperature so as to avoid weakening the bond between the FBE coating and the underlying steel pipe. The number and sequence of steps can be varied, depending at least partly on whether the liquid epoxy and adhesive layers are applied in a pipe coating facility or in the field.
    • 一种用于在涂覆或绝缘管道的部分之间形成场接头的方法,其将被焊接在一起并被并入到用于承载单相或多相流体例如油,气和水的海底管道中。 该方法包括施加与工厂施加的FBE涂层的唇部重叠的液体环氧树脂层,突出超出工厂绝缘层的倒角端,并且可以施加在整个焊接接合区域上。 液体环氧树脂层通过加热部分地固化,并且将一层粉末状粘合剂施加到部分固化的液体环氧树脂层上。 粘合剂随后通过向其外表面施加热而烧结并活化。 然后将粘合剂层和倒角的外表面预热,并且在整个接合区域注射模制热接头绝缘体。 在整个方法中,工厂应用的FBE涂层的温度保持在其玻璃化转变温度以下,以避免削弱FBE涂层和下层钢管之间的粘结。 步骤的数量和顺序可以变化,这取决于至少部分地基于液体环氧树脂和粘合剂层是施加在管道涂布设备中还是应用于现场。

    • A wrappable, styrenic thermal insulation product for application to flexible, armoured pipe is in the form of an elongate tape of generally rectangular cross-section, optionally being provided with interlocking and/or overlapping portions so as to provide a continuous insulating layer when one or more layers of the tape are wound around the pipe. The interlocking and/or overlapping portions may be of various configurations. The tape is comprised of polystyrene or a styrene-based thermoplastic having high compressive creep resistance, high compressive strength and low thermal conductivity and may be foamed or unfoamed. A flexible, armoured pipe incorporates one or more layers of the wrappable, styrenic thermal insulation product between an outer armour layer and an outer polymeric sheath.
