For example, Chinese patent 200520112528. 4, which is filed on July 4, 2005, discloses a plastic steel wound structural wall pipe. As shown in Fig. 1, the pipe 1 is composed of a closed smooth fluid passage formed by the inner wall l1, and the outer surface of the pipe wall is a spiral-wrapped steel belt reinforced solid straight rib structure lb. By providing a steel strip reinforcing rib lb, the pipe wall is lowered.

Due to the large stress concentration at the joint between the branch pipe and the main pipe, it is a weak link in the pipe tee structure. The structure is often due to stress concentration, and the cracking failure first occurs in use. Therefore, how to make the branch pipe and the main pipe joint structure Strengthening, meeting the strength and requirements of steel strips has become an important part of ensuring the reliable operation of the coiled pipe system.
