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。当前，市面上最为流行的是钢带增强钢塑复合管，也就是我们 常说的钢塑复合压力管，这种管材中间层为高碳钢带通过卷曲成型对接焊接而成的钢带层，内外层均为高密度聚乙烯（HDPE）。
There are many kinds of steel plastic composite pipe, which can be classified according to the structure of the pipe: steel belt reinforced steel plastic composite pipe, seamless steel tube reinforced steel plastic composite pipe, steel plastic composite pipe with mesh hole and steel mesh framework. At present, the most popular one on the market is steel strip reinforced steel plastic composite pipe, which is often referred to as steel plastic composite pressure pipe. The middle layer of the pipe is a steel strip layer made of high carbon steel strip by crimping and butt welding, and the inner and outer layers are HDPE.
这种管材中间层为钢带，所以管材承压性能非常好，不同于铝带承压不高，管材最大口径只能做到63mm，钢塑管的最大口径可以做到200mm，甚至更大；由于管材中间层的钢带是密闭的，所以这种钢塑管同时具有阻氧作用，可直接用于直饮水工程，而其内外层又是塑料材质，具有非常好的耐腐蚀性。如此优良的性能，使得钢塑复合管的用途非常广泛，石油、天然气输送，工矿用管，饮水管，排水管等等各种领域均可以见到这种管的身影。
The middle layer of the pipe is steel strip, so the pressure bearing performance of the pipe is very good. Different from the aluminum strip, the maximum diameter of the pipe can only be 63mm, and the maximum diameter of the steel plastic pipe can be 200mm, or even larger. Because the steel strip of the middle layer of the pipe is sealed, the steel plastic pipe has the function of oxygen resistance at the same time, which can be directly used in the direct drinking water project, while the inner and outer layers are plastic Material, with very good corrosion resistance. With such excellent performance, the steel plastic composite pipe is widely used in oil and natural gas transportation, industrial and mining pipes, drinking water pipes, drainage pipes and other fields.
