涂塑属于输水管道新型的防腐方法,与镀锌管相比,具有明显的优越性。我所研制的涂塑钢管经上海自来水公司检测、部份试用和有关部门的测定,具有以下特点: (1)涂层完整、光滑、厚度均匀,管径损失小。 (2)具有可靠的防腐性能。在钢管涂覆前对表面进行特殊处理,使聚乙烯粉末在表面完全熔融,不因外界条件的变化而产生剥落,内壁涂层厚度达0.3mm左右。使用过程中不会产生锈蚀,能大大延
Plastic coating is a new type of pipeline corrosion, compared with the galvanized pipe, with obvious advantages. The plastic pipe developed by our company has been tested by Shanghai Water Supply Company and has been partially tested and measured by relevant departments. It has the following characteristics: (1) The coating is complete, smooth and uniform in thickness with small diameter loss. (2) has a reliable anti-corrosion properties. In the steel pipe before the special treatment of the surface, so that the surface of the polyethylene powder completely melted, not due to changes in external conditions and spalling, the inner wall coating thickness of about 0.3mm. Will not produce rust during use, can greatly delay
