AI Technical Summary
Technical Problem
Existing metal and plastic pipes are insufficient in terms of strength, impact resistance and lightweight. The traditional method of increasing wall thickness increases cost and weight, and the simple inner wall structure cannot meet multiple performance requirements.
Method used
The honeycomb wire mesh is combined with the plate by rolling to form a pipe with a honeycomb mesh structure on the inner wall. It is manufactured by rolling, slitting, rolling and welding processes to ensure that the honeycomb wire mesh and the plate are tightly bonded.
Benefits of technology
It improves the overall strength and impact resistance of the pipe, achieves lightweighting, reduces production and transportation costs, and also has a flow guiding function, making it highly cost-effective.

Abstract
The invention discloses a machining method for a pipe with the inner wall provided with a honeycomb net-shaped structure, and relates to the technical field of pipe machining. The processing method comprises the following steps: rolling and combining: putting a layer of honeycomb-shaped steel wire mesh and a plate into rolling equipment together, and rolling the honeycomb-shaped steel wire mesh and the plate into a whole in a rolling manner, so that the honeycomb-shaped steel wire mesh is tightly attached to the surface of one side of the plate; the rolled and combined plate is divided into long strips according to the preset size; pipe rolling forming is conducted, specifically, the slit long-strip plate is subjected to pipe rolling operation, the side, provided with the honeycomb-shaped steel wire net, of the long-strip plate faces the inner side, and a tubular structure is formed; and welding and fixing: welding the seam of the tubular structure formed after pipe coiling by adopting a high-frequency welding or laser welding mode to prepare the pipe. The honeycomb-shaped steel wire mesh is arranged on the inner wall of the pipe, the honeycomb structure has good mechanical performance, pressure and impact force borne by the pipe are effectively dispersed, the overall strength and impact resistance of the pipe are remarkably improved, and the service life of the pipe is prolonged.
