介绍了几种适用于金属型离心铸管涂料的涂敷工艺；分析了离心铸管产生裂纹、管尾不完整、气孔及参漏等缺陷与涂料涂敷工艺的内在联系，并提出了相应的防止措施；设计并使用了新型喷咀及涂料喷涂系统，从而使铸管质量得以大大提高，同时延长了铸型的使用寿命
Several kinds of coating processes for metal centrifugal casting pipe coatings are introduced. The internal relations between the defects such as cracks, incomplete pipe ends, porosity and ginseng leakage and coating coating process are analyzed. The corresponding Preventive measures; New nozzle and coating systems have been designed and used to improve the quality of the castings and at the same time extend the service life of the castings
