Embodiment Construction

[0021] As shown in the figure, the steel pipe outer wall sandblasting equipment of the present invention supports the steel pipe through the support block 5 on the trolley 1 and the support column 3 on the sandblasting box. The dust board enters the sandblasting box, and after entering the sandblasting box, the sandblasting machine starts at the same time, and the active friction wheels 7 and 8 drive the steel pipe to rotate at a constant speed, ensuring that the outer wall of the steel pipe is sandblasted evenly. Push away the rubber dust-proof plate at the output end of the sandblasting box and reach the upper support block 6 of the trolley 2. The trolley 2 starts and drives the steel pipe to move in the same direction and at the same speed as the trolley 1 until the steel pipe is blasted.

[0022] If the sandblasting effect is unsatisfactory after the steel pipe is completed from input to output, similarly, you can start the trolley 2 to move in reverse, enter from the left ...

Abstract

The invention relates to sand blasting equipment for the outer wall of a steel pipe, which comprises a transportation support component and a sand blasting component, wherein the transportation support component comprises trolleys (1) and (2) and support posts (3) and (4), and the sand blasting component comprises a sand blasting machine and a sand blasting box. The invention is characterized in that the steel pipe is pushed to enter the sand blasting component through the trolleys, the sand blasting machine carries out sand blasting, a friction wheel of the sand blasting box drives the steel pipe to rotate at the constant speed, and the goal of controlling the uniform sand blasting on the surface of the steel pipe is reached.

Description

technical field [0001] The invention relates to a steel pipe auxiliary processing equipment, in particular to a steel pipe outer wall sand blasting equipment Background technique [0002] With the continuous development of my country's economy, the country vigorously develops the energy industry. Long-distance oil and gas pipelines are an important way of energy protection. During the anti-corrosion construction process of oil and gas pipelines, the surface treatment of steel pipes is one of the key factors that determine the service life of pipeline anti-corrosion. It is It is the premise of whether the anti-corrosion layer and the steel pipe can be firmly combined. It has been verified by research institutions that the life of the anti-corrosion layer depends on factors such as coating type, anti-corrosion process, coating quality, and construction environment. The surface treatment of steel pipes has an impact on the life of the anti-corrosion layer. In order to meet the ...
