Problems solved by technology

[0003] In the prior art, for the derusting of steel pipes, the derusting of the inner surface and the derusting of the outer surface are usually carried out separately. The separate operation process is not only complicated, but the derusting efficiency is low, and two separate equipments are required, and the equipment cost High, large footprint

Embodiment 1

[0047] see figure 1 , a process for simultaneously removing rust on the inner surface and the outer surface of a steel pipe, comprising the following steps:

[0048] S1, steel pipe fixing: pass one end of the steel pipe through the support ring 204 and clamp it to the steel pipe clamp 203, so as to fix the steel pipe to the manual travel assembly of the double-sided simultaneous removal device;

[0049] S2. Adjust the connection: turn the handle 208 to drive the steel pipe through the circular through hole 210 and approach the electric grinding assembly until the pipe wall at the top of the steel pipe is between the outer surface grinding block 108 and the inner surface grinding block 109, then turn the adjustment lever 104 make the outer surface grinding block 108 and the inner surface grinding block 109 move toward each other until the outer surface grinding block 108 and the inner surface grinding block 109 are respectively close to the outer surface and the inner surface o...

Abstract

The invention discloses a simultaneous derusting process for the inner surface and the outer surface of a steel pipe, which belongs to the technical field of steel pipe derusting. A simultaneous derusting process for the inner surface and the outer surface of a steel pipe comprises the following steps: S1, fixing the steel pipe; ; S3, linkage derusting; S4, turning both ends; S5, rear end derusting, S6 flushing and spraying. It can be combined with the rust removal process and is equipped with a double-sided simultaneous removal device, which can grind and remove rust on the inner and outer surfaces of the steel pipe at the same time. The process is simple, the rust removal efficiency is high, the equipment cost is low, and the floor area is small. The driving method, the more labor-intensive grinding, is handed over to the electric grinding component to be driven by the motor, and the manual travel component is used to manually control the travel of the steel pipe during the rust removal process, so that it can be controlled more accurately according to the site conditions. The travel of the steel pipe avoids incomplete rust removal, improves the work quality, and is easy to operate and consumes little physical strength.

Description

technical field [0001] The invention relates to the technical field of derusting steel pipes, and more specifically relates to a process for simultaneously derusting the inner and outer surfaces of steel pipes. Background technique [0002] Steel pipe is an economical cross-section type of steel with a wide range of sizes, whether it is a capillary tube with a small diameter or a large diameter steel pipe with a diameter of several meters. It is characterized by not only openings at both ends but also a closed hollow section, and the ratio of its length to the perimeter of the cross-section is usually relatively large. Seamless steel pipes not only have round but also square, rectangular and other special-shaped cross-sections. Steel pipes are not only widely used in aerospace, shipbuilding, coal mine construction, boiler manufacturing, petroleum energy, construction and military industry, but also in home appliance manufacturing, bicycles, agricultural machinery and tools,...
