发明名称 Pipe assembly and flow assurance system
摘要 A pipe assembly comprising an outer pipe in surrounding relation about an inner pipe, wherein the inner pipe is suspended in free inner ends of legs extended in an annular space that is formed between the outer and inner pipes, the legs reaching radially towards the inner pipe from an inner periphery of the outer pipe. At least one of the legs carries in its inner end a support foot that is formed with a recess facing towards the inner pipe. The recess forms a tunnel that is defined through an outer periphery of the inner pipe and opposite tunnel walls that reach from the leg to the inner pipe.

主权项 1. A pipe assembly comprising: an outer pipe in surrounding relation about an inner pipe, wherein the inner pipe is suspended in free inner ends of legs extended in an annular space that is formed between the outer and the inner pipes, the legs reaching radially towards the inner pipe from an inner periphery of the outer pipe, wherein at least one leg of the legs in its inner end carries a support foot that is formed with a recess facing towards the inner pipe, and wherein the recess forms a tunnel that is defined through an outer periphery of the inner pipe and opposite tunnel walls that reach from the at least one leg to the inner pipe, wherein the legs and the tunnel walls are flexible and provide an elastic suspension of the inner pipe, and wherein the tunnel walls are cup-shaped in sectional view, and the edges of the tunnel walls that face the inner pipe are formed with a radius corresponding the outer radius of the inner pipe.
