Abstract
A hard pipe connecting device and manifold system are disclosed that solve technical problems of existing fracturing pipelines, such as poor safety performance, too many connecting parts, inconvenient and ineffective connection between the parts, complicated installation structure, and difficulty to adjust the distance and the angle. In order to solve the technical problems, the hard pipe connecting device includes at least one non-concentric connecting pipe joint, which includes a pipe body and first flanges at opposite ends of the pipe body. The two first flanges are parallel to each other with a distance difference h, where h>0.
