When choosing the best type of pipe, you must make a survey before purchasing any. You can’t just blatantly get anything that you see and try to make things work. There are a few common types of pipes that are usually used in piping. Among them are ductile iron pipe and PVC pipe. You might have heard of and seen PVC pipes before, but have you heard of ductile iron pipes? This kind of pipe has many advantages that you should know. You should get ductile iron pipe Malaysia so that you will acquire the benefits. 

Ductile Iron Pipe Definition

Ductile iron pipe is made of ductile cast iron. Ductile cast iron, also known as ductile iron and spheroidal graphite cast iron is one of the types of graphite-rich cast iron. The graphite contains a spheroidal-shaped molecular structure, which would make cast iron to be less brittle and more impact resistant than other variants with flaky structures. They are said to be able to last for more than a century, as long as they are covered inside and out with non-corrosive linings. Examples of non-corrosive linings are polyethylene, cement, paint and asphalt. This type of iron is highly reliable due to its durability and strength. It is corrosion resistance too, which is very crucial in pipings. Ductile iron pipes are normally utilised for the distribution of potable water and to process chemicals.


Ductile Iron Pipe VS PVC Pipe

To be clear, ductile iron pipe holds more benefits than PVC pipes. There are many important aspects and features that ductile iron pipes have compared to PVC pipes. 

  • Durability

As mentioned before, ductile iron pipes are highly reliable due to their durability. They can last for more than 100 years with proper handling. Durability is one of the most important features that most people are looking for. This is probably why many people prefer to use ductile iron pipes. 

As for PVC pipes, they are known to be durable too. They can last about 80 to 100 years with good and proper maintenance. However, if they are used above ground and often being directly exposed to sunlight, they can break down even faster than they should. This is due to the UV rays, making them easy to brittle and later break. 

  • Cost-effective

We are always looking for something that is both durable and cost-effective. In the previous point, it has been stated that this type of pipe is durable, which means you might not have to replace it up until 100 years. Most people would not think of replacing pipes as they should last up for many years.

PVC pipes on the other hand are almost the same. They are not too expensive, but they all depend on the size. The bigger the pipe is, the price might increase. 

  • Unharmful material

Ductile iron pipe is formed from iron and steel that have been recycled and is manufactured to the most stringent and conservative industry requirements.

PVC pipes are manufactured using petrochemicals in a process that is hazardous to the environment and our health. This is also very vital in making sure that the pipes we use are safe for all living creatures and the environment. 


Choosing a correct and suitable pipe for your use is very crucial. Based on this comparison, we hope that you will succeed in finding the best type of pipe that is compatible with your use.
