1、性质不同:钢塑复合管产品以无缝钢管、焊接钢管为基管,内壁涂装高附着力、防腐、食品级卫生型的聚乙烯粉末涂料或环氧树脂涂料。PVC主要成份为聚氯乙烯,加入其他成分来增强其耐热性、韧性、延展性的一种材料。

2、特点不同:钢塑管采用前处理、预热、内涂装、流平、后处理工艺制成的给水镀锌内涂塑复合钢管。pvc管表面膜的最上层是漆,中间的主要成分是聚氯乙烯,最下层是背涂粘合剂。

3、分类不同:PVC可分为软PVC和硬PVC。钢塑复合管有很多分类,可根据管材的结构分类为钢带增强钢塑复合管,无缝钢管增强钢塑复合管,孔网钢带钢塑复合管以及钢丝网骨架钢塑复合管。

注意事项:

1、在安装钢塑复合管的时候,需要保存完整,要检查一下各部件看有没有出现裂痕或者是划痕。

2、要保证钢塑复合管的内径不能出现缩小的情况,切割面也要比较平齐。

3、使用切割机去切割的时候,要把管道必须垫平。切完对管口扫口。要保证干净。在加工丝扣的时候,需要保证带丝的刻度调整准确,压力头压紧管道,带丝的板牙面与管道的轴线垂直,套丝的时候要加一些润滑油,当板牙面与管口平齐时,开始加工梢头。

4、套完丝用相应的管件试一下。检查一下看有没有断丝、残丝的情况。如果有那么需要及时的处理干净。

楼上一看就是复制的答案那是制作工艺不是区别那我就补充下吧
钢塑管分为涂塑管和衬塑管 两者工艺不同 价格也不尽相同 衬塑要贵 由于钢塑管的钢部分与介质是隔离的所以一般情况无须防腐 PVC就是聚氯乙烯管主要是用做排水和雨水系统 一般情况为粘接 由于材质比较脆所以一般用在无压力管路中 做给水一般用的塑料的管为PP-R三型聚丙烯管它具有较好的抗冲击性能和长期蠕变性能 对于给水系统能很好的起到承压作用 所以塑料给水管多采用PP-R
至于国家标准么是钢塑管取代镀锌钢管 塑料管是PP-R或PE给水管 PVC由于相对比较硬 多用于排水尤其是UPVC
希望对你有所帮助

钢塑复合管是以普通碳素钢管作为基体,内衬化学稳定性优良的热塑性塑料管,经冷拉复合或滚塑成型,它既有钢管的机械性能,又有塑料管的耐腐蚀,缓结垢,不易生长微生物的特点,是输送酸、碱、盐、有腐蚀性气体等介质的理想管道。
PVC,全名为Polyvinylchlorid,主要成份为聚氯乙烯,另外加入其他成分来增强其耐热性,韧性,延展性等。这种表面膜的最上层是漆,中间的主要成分是聚氯乙烯,最下层是背涂粘合剂。它是当今世界上深受喜爱、颇为流行并且也被广泛应用的一种合成材料。
