钢管外壁除锈设备

钢管外壁抛丸机用途及工艺：

本机为钢管外壁清理机，钢管经抛丸可去除外壁金属表面的锈蚀及氧化皮，获得一定粗糙度的光亮表面，达到钢管外壁防腐前的要求，从而提高瓷漆的附着力。该机具有清理多规格管径的功能，它适用于锅炉、自来水、石油、天然气等行业钢管的外表面处理，并可通过辊道输送与喷漆、烘干组成连续作业生产线。该工艺是利用高速旋转的抛丸器带动弹丸并使之加速同时抛出，打击钢管外壁，去除其表面的氧化皮、锈蚀和焊渣等，从而达到去除焊接应力，增加钢管表面的锚纹深度，从而增强钢管表面的附着力，大大提高了聚氨酯与钢管外壁的粘接强度，使保温管材的钢管与保温层紧密结合成一体。

本机有如下主要特点：

1、抛丸器采用垂直向上抛丸布置。由于管径不同钢管在辊道输送时其可保证管底高不变，抛丸器从下向上抛射，抛丸器的抛射距离不变，即能达到均匀的清理效果。

2、工件连续通过抛丸器的进出口，因清理管径悬殊的钢管，为防止弹丸外飞，本机采用多层可换式密封，实现对弹丸的彻底密封。

3、多功能抛丸机，抛砂量大，效率高，宽抛射带，叶片更换迅速，维修方便。

The steel pipe outer wall shot blasting machine is a new type of steel pipe outer wall shot blasting equipment developed by our company based on the introduction of technology from the United States and Italy, using modern computer simulation technology. It can remove the oxide skin on the surface of the steel pipe, fully meeting the cleaning requirements of the steel pipe outer wall before coating, and can meet the needs of large and medium-sized engineering steel pipe outer wall cleaning.

advantage

(1) Adopting the popular small pit structure form, it saves the construction cost and time of the pit foundation, and solves the problem of rust and agglomeration of shot sand inside the elevator caused by water storage in the pit.

(2) The use of the fifth generation cantilever centrifugal shot blasting machine with large shot blasting volume and high blasting speed significantly improves cleaning efficiency and achieves satisfactory cleaning quality.

(3) This equipment is a redesigned steel pipe shot blasting machine based on domestic and foreign technology. The machine is driven by a high-power motor to rotate the blades of the shot blasting machine at high speed, causing abrasives such as steel sand, steel shot, and steel wire cutting shot to spray (blast) the surface of the steel pipe under centrifugal force. It can remove rust, oxides, and dirt without accumulation. Moreover, the steel pipe is subjected to strong impact and friction force from the abrasive, It can still achieve the required roughness.
