Abstract

The invention relates to a bending limiter, and belongs to the technical field of production. The bending limiter comprises n round tubes and (n-1) connecting rings, wherein the two mutual adjacent round tubes are connected by one connecting ring, and the n is an integer greater than or equal to 2. The bending limiter provided by the invention has the advantages that the installation flexibility is high, and the replacement performance is good.

Description

technical field [0001] The invention relates to a bend limiter, which belongs to the technical field of protection. Background technique [0002] Hoses and umbilicals are flexible pipes that are easy to bend. In order to protect hoses and umbilicals from excessive bending when subjected to external loads, bend limiters are usually used in pipe sections with large external loads. Most of the existing bend limiters adopt end-to-end embedded design, the first end of the bend limiter is female, and the end is male. When installing, the first end of the bend limiter is put on the end of the previous bend limiter, one by one, until all the bend limiters are installed. If one of the bend limiters is to be replaced, this bend limiter and all subsequent bend limiters must be removed. In addition, if it is necessary to open a certain bend limiter to check the hose or umbilical cable inside, all the bend limiters must be removed, which will cause a lot of inconvenience to the constru...
