Subsea oil and gas pipelines are genially required concrete to add weight. Asphalt mastic, high-density polyurethane foam are used forfield joint coating of weight layer joints. There is another design of“No-filling material”. The characteristics of different kinds offield joint coating technology are analyzed from aspects of filling materials and construction process. Existing problems of current technologies in the use offield joint coating are pointed out and the develop trend is also proposed.
