Abstract
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.
