| 摘 要： | 介绍了一种先对管坯(带钢)表面进行热涂敷，再将处理后的带钢加工成钢管的工艺方法。通过对采用这种工艺制成的两种不同规格焊管的性能和生产工艺的研究，指出在涂敷过程中，可采用对涂敷层先进行10％的厚度压缩，使涂敷层预先塑性变形以及沿带钢宽度方向喷敷不同厚度涂敷层(即从带钢中线向板侧边逐渐增加喷敷厚度)的方法，提高成型后钢管涂敷层的均匀性，从而改善涂敷层的耐腐蚀性能。

| Abstract: | It presents a process method which it hot applies on the surface of strip first and then formed pipes with strips well treated. It indicates the method that it can adopt to compress 10% thickness after applying and make the coated layer pre plastic deformation as well as applies different thicknesses layers (i.e.gradually increasing applying thickness from centre line of strip) along with the direction of strip width during coating to increase the uniformity of coating layers after forming and improve anti-corrosions properties of coated layers by researching the properties and production process of this process method to produce two different sizes welded pipes. |
