The dispute about which material should be used for pipe lasts many years and it is mainly centered on two materials - steel and plastic. Generally speaking, black steel pipes have more support than plastic pipes. Now let's contrast the differences between black steel pipe and plastic pipe.

The main advantages of plastic pipes are the following: Plastic pipes are light in weight, available in different lengths, good elastic properties, tough, resistant to chemical; the cost of handling, transportation and installation is relatively low; less number of joints and reduces chances of leakage; less friction due to smooth surface and saves energy in delivery. Plastic pipes are in widespread use in many different industries, they are valuable as a thermo resistant, fire retardant and usually used as water conduit in many construction applications. They are useful for maintaining quality in water. One of the most tempting qualities of black steel pipe is its longevity. Black steel pipe's molecular density silences noise, and the rubber gaskets used to join the pipe can largely reduce the transmission of vibration through the system. They can reduce noise 750% better than plastic pipe. Another reason that makes black steel pipe more popular than plastic pipe is that black steel pipe's low coefficient of expansion and contraction.

Plastic pipes offer lower expense for installation. However, several major differences exist between black steel pipe and plastic pipe, and these differences are crucial when choosing materials. Black steel pipe is not combustible therefore can prevent the spread of fire better than plastic pipe. Fire will not burn away in black steel pipe so can reduce the affected area when fire break out. On the contrary, plastic pipe is combustible and fire can spread to other parts and cause serious result. What's more, to stop a fire from combustible pipe take lots of work and the cost is expensive while it's relatively easier to stop in black steel pipe. It takes much less money to have a same effect.

Another important difference between black steel pipe and plastic pipe is strength. Black steel pipe can support more weight than plastic pipe, they are tough, and you can hardly find any deflection in black steel pipes. Unlike black steel pipe, plastic pipe is more flexible and it is easy to break and bend under pressure and heavy weight. Plastic pipe requires special trench width, special bedding and hand compaction which are uneasy and need extra cost for installation while black steel pipe don't need this expense. Finally but not least, and perhaps the most significant advantage of black steel pipe has over plastic pipe is that it is recycled. Environmental consciousness has come to the forefront of people's minds in recent years. Steel is an environmentally friendly material. In contrast, the plastic in PVC and ABS pipe has very little value of recycle; therefore plastic pipe is less friendly to the environment.

But plastic pipe has its own strong point. Considering economic factor, many companies choose plastic pipe because its low cost. The cost of installing plastic pipe is very important to a project, and plastic pipe is both effective and efficient, they are very popular because they are light, easy to install and easy to repair. Through the differences between black steel pipe and plastic pipe, you will have a clear idea about which one is better. The welded steel pipe and API steel pipe are also available.
