Abstract

The invention relates to the technical field of corrugated pipes, and discloses a processing method for corrugated pipes, which is used to process seamless steel pipes into corrugated pipes, comprising the following steps: fixing the seamless steel pipes; into the seamless steel pipe, and towards the side wall of the seamless steel pipe; the nozzle is rotated around the axis of the seamless steel pipe, and the high-pressure water jet sprayed by the nozzle makes the side wall of the seamless steel pipe form a corrugated ring . Compared with the prior art, in the above-mentioned processing method, the high-pressure water jet is sprayed through the nozzle of the spray gun, so that the corrugated ring is formed on the side wall of the seamless steel pipe, and the seamless steel pipe is formed into a corrugated pipe, which is directly processed by water flow, and its flexibility processing, avoiding welding operations, so as to ensure the quality of the bellows, the production has a wide range of applications, and the cost is low.

Description

Technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a processing method and equipment of the corrugated pipe. Background technique [0002] The bellows is a flexible structure arranged on the container shell or pipeline, which can be used as an elastic compensation element that can expand and contract freely. [0003] In the prior art, there are two main processing methods for corrugated pipes. First, select steel plates for stamping, that is, stamping into the shape of the corrugated pipe along the axis, and then weld the two parts together to form the corrugated pipe; Seamless steel is used as the blank material of the corrugated pipe, and the seamless steel pipe is produced by hydraulic bulging. [0004] The main shortcomings of the corrugated pipe processing method in the prior art are high cost and poor processing adaptability. It is suitable for mass production. However, with the development of production, users’ requiremen...
