Abstract: A method of coating a field joint and a coated field joint formed thereby. The field joint coating includes a first thermal insulation material injection molded over the uncoated field joint to form a first layer, and a second thermal insulation material injection molded over the first layer to form a second layer. The second material has a greater flexibility than the first material and a lower maximum operating temperature than the first material. In certain embodiments, the second material forms a significant part of the volume of the field joint coating.

Abstract translation: 由此形成的场接头和涂覆的场接头的涂覆方法。 场接合涂层包括在未涂覆的场接头上注射成型以形成第一层的第一绝热材料和在第一层上注射成型以形成第二层的第二绝热材料。 第二种材料比第一种材料具有更大的灵活性和比第一种材料更低的最大工作温度。 在某些实施方案中，第二种材料形成场接合涂层体积的重要部分。
