Abstract

This utility model relates to the field of straight seam welded pipe technology, and proposes a straight seam welded pipe with an external protection structure. The pipe includes a pipe body with an external protection structure installed on it. The external protection structure includes an outer plate, protective cylinders, protective rings, an adjustment assembly, an adjustment component, an adjustment component, and a limiting pad. A protective groove is formed at the top of the outer plate, and an anti-slip pad is fixedly connected inside the groove. Multiple protective cylinders are in contact with the anti-slip pads, and the pipe body is located on the upper side of the outer plate. Multiple protective cylinders are arranged in an array on the outer plate, and the pipe body is connected to the multiple protective cylinders through them. A sponge pad is fixedly connected to each of the multiple protective cylinders, and each sponge pad has a through-hole matching the pipe body. Two protective rings are movable towards each other inside each protective cylinder. This technical solution solves the problem in the prior art where it is inconvenient to adjust the external protection range according to the specifications of the straight seam welded pipe.
