Hexagonal steel pipe not easy to bend and deform

Abstract

The invention discloses a hexagonal steel pipe not easy to bend and deform. The hexagonal steel pipe comprises an inner pipe, first stable steel pipes and an outer pipe. Internal friction convex points are uniformly fixed and welded on the inner wall of the inner pipe. The internal friction convex points are circumferentially and equidistantly arranged along the inner wall of the inner pipe from front to back. The first stable steel pipes are annularly arranged on the outer side of the inner pipe. The number of the first stable steel pipes is six groups. Second stable steel pipes are insertedinto the inner parts of the first stable steel pipes. The outer side of the inner pipe is sleeved with the outer pipe. External friction convex points are uniformly fixed and welded on the outer surface of the outer pipe, the external friction convex points are equidistantly arranged along the outer surface of the outer pipe from front to back, and six groups of silica gel rods are annularly and equidistantly arranged on the outer side of the inner pipe. The hexagonal steel pipe is hollowed-out in structure, light in weight, capable of greatly reducing production materials, high in strength and not easy to bend and deform due to the influence of external factors.

Description

technical field [0001] The invention relates to the technical field of hexagonal steel pipes, in particular to a hexagonal steel pipe that is not easily deformed. Background technique [0002] Hexagonal steel pipes are also called special-shaped steel pipes, including octagonal pipes, diamond-shaped pipes, oval pipes, etc., which are widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial Furnaces, reaction towers, container racks and warehouse shelves, etc., the existing hexagonal steel pipes are not strong enough in application, and they are easily bent and deformed by external factors after long-term use. Therefore, we propose a hexagonal steel pipe that is not easily deformed. Solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a hexagonal steel pipe that is not easy to bend and deform, so...
