Abstract
The invention discloses a stainless steel pipe fitting with spiral connecting pipes. The stainless steel pipe fitting with the spiral connecting pipes comprises an inner pipe and an outer pipe arranged outside the inner pipe, wherein connecting pipes are arranged on the outer wall of the inner pipe and spirally surround the outer wall of the inner pipe; the inner sides of the connecting pipes are connected with the inner pipe; the outer sides of the connecting pipes are connected with the outer pipe; supporting pipes are arranged in a pipe body; each supporting pipe is composed of an inner supporting pipe and an outer supporting pipe which carries out support matching with the corresponding inner supporting pipe; the inner supporting pipes are arranged on the outer wall of the inner pipe and spirally surround the outer wall of the inner pipe in the axial direction; the outer supporting pipes are arranged on the inner wall of the outer pipe and spirally surround the inner wall of the outer pipe in the axial direction; and a supporting interval is formed between the outer edge of each inner supporting pipe and the inner edge of the corresponding outer supporting pipe. According to the stainless steel pipe fitting with the spiral connecting pipes, by arranging the inner pipe in the outer pipe and connecting and fixing the inner pipe and the outer pipe together through a certain structure, the thickness of the pipe wall is lowered, and the strength can also be ensured when the weight is lightened.
