细长管内壁喷砂除锈作业线的设计

Development of the spraying sand operative-line for removing rust on the interior walls of slight pipe

以 2 5英寸防腐油管为研究对象 ,采用先进的喷射装置和砂粒的自动回收与分离技术 ,设计一条细长钢管内壁喷砂半自动作业线。试验结果 :作业线动作准确 ,工作稳定 ,除锈质量达到瑞典工业标准Sa2 5级 ,生产率达30m2 /h以上。同时配合三废治理 ,改善了劳动条件 ,是替代钢管酸洗的理想工艺 ,可望在石油、化工。

It researches the corrosion resistant for 2.5 inch oil pipe. With the help of spraying sand device and self-retrieval technique, it designs spraying sand line of interior walls of steel pipe. The tests show that the operative-line is accruate and stable. The quality of production reaches to Sweden Industry Standard Sa2.5. and the efficiency surpasses 30m2/h. This line can treat wastes and improve operator's working conditions, and be used in many fields such as oil industry, chemical industry, shipbuilding etc.
