钢塑复合管以钢管为骨架，内衬塑料粉末加入改性剂、交联剂及粘结剂后，产品性能大幅度提高，增强了稳定性。产品按衬塑层材料划分为：钢衬聚乙烯复合管（S/PE）、钢衬聚丙烯复合管（S/PP、PO）、钢衬聚四氟乙烯复合管（S/PTFE），各种直管、弯头、三通、异径管和盲板等。
性能及特点
·耐腐蚀：衬塑层对无机酸、碱、盐、气体（H2S、S、CO2、天然气、煤气）醇类、酮类、芳胺等介质具有较强的稳定性和良好的防腐性能。
·耐老化：衬塑层的材料中按比例加入改性剂、交联剂和粘结剂等化学功能剂、激活衬塑层分子内部低极性的饱和脂肪烃交联结构、结合强度高、抗应力开裂和耐老化性能强。
·抗冲击、耐低温：由于衬塑层材料的脆性温度低、分子链柔韧，所以适用于-35℃—95℃的工作范围长期使用，耐冲击性能强。
·耐低压、强度高：由于钢塑复合管采用钢管为基体、钢管内壁经过严格的喷砂、酸洗、淋化和钢管加温将内衬塑料粉末离心复合等加工工艺、增加了钢管与内衬塑料层的结合强度，可承受-0.035MPa的压力，而不出现脱层、凸起及开裂的现象。
主要技术指标
用途及造价
钢塑复合管具有耐腐蚀、耐老化、耐冲击、耐低温、耐低压，强度高等优异的综合性能。而广泛应用于化工、石油、天然气、电力（锅炉软化水、脱硫废水系统）、冶金、造纸、制药、环保等行业。逐步取代了成本造价较高的不锈钢、衬胶等产品，降低了搬运和现场安装费用，是用户首选的理想防腐蚀管道。
运输及安装
·钢塑复合管在运输、搬运及安装过程中，管件端面的衬塑层翻边严禁刮、割、划或与硬物碰撞，如有损伤应修复后使用。
·钢塑复合管安装采用法兰或快速接头连接方式，严禁对钢塑复合管本体进行切割和焊接等操作。
·钢塑复合管如长期存放，应避免阳光暴晒，远离热源及油污，以防老化、变形和污染。
