What Metal is Used For Pipes in Plumbing in Houses?

Over time, the material composition of plumbing pipes has changed multiple times, moving from metal to plastic. Although there were some difficulties with this change, plumbers now find that installing plastic pipes and connectors is simpler. You might be wondering about the metal that is used for pipes in plumbing service.

In this blog post, we are going to discuss different types of metal used for pipes during plumbing in houses and many more. So, take a moment and read the following details!

Different Types of Metal Pipes Used in Plumbing

You may find several types of pipes in the house, depending on how old it is and whether it has recently undergone renovations. A few of the most typical piping materials seen in modern homes are listed below.

Copper Pipes

Copper pipes have long been used in homes as plumbing systems since it does not break easily and is naturally antibacterial. It is most used where there is a supply of gas and pipelines used for both hot and cold water. There are two primary varieties of copper pipes: some are flexible and the others are stiff.

While the second is preferably used in limited space, the former is commonly used in water supply pipes. The most important benefits of copper are its heat resistance, its possibility to be used in conditions from -50 to +120 C and its service life of more than 50 years. However, cost has played a large part in recent times, forcing builders and homeowners to look for an alternative to copper.

Galvanised Steel Pipes

Due to their strength and longevity, older homes frequently employed galvanised steel pipes. These pipes are made of steel and have a zinc coating on them to stop rust and corrosion. 

Although galvanised pipes were common for many years, they are no longer as popular because of the possibility that the inner lining could rust and corrode with time, resulting in low water pressure and problems with water quality.

Stainless Steel Pipes

Stainless steel piping is utilised in coastal regions and areas that are susceptible to corrosion, but it is less prevalent due to its higher cost. Stainless steel pipes are renowned for their durability, strength, and ability to withstand corrosion. They are frequently utilised in high-end projects or unique applications where their benefits justify the cost for both gas and water supply lines.

Brass Pipes

Brass, a copper and zinc alloy, is a good option for hot water systems and places with harsh water because of its exceptional corrosion resistance. Brass pipes are extremely resistant to rust and have a longer lifespan than many other metals. Moreover, threading them is simpler than with steel pipes. Brass pipes are a robust choice for plumbing systems because they may endure up to 70 years or more.

Factors to Consider When Choosing Metal Pipes

When choosing metal pipes, several factors must be considered to ensure optimal performance, durability, and cost-effectiveness.

  • Material Type: It is for this reason that stainless steel, carbon steel, copper or aluminium depend on their applications. It is used where corrosion is present and where strength is needed, compatible with tough conditions. Copper alloy is the most suitable for plumbing because of its inherent antibacterial characteristics and installability. Carbon steel exhibits high tensile strength for applications such as structural purposes but it can corrode easily and necessitates coating.
  • Corrosion Resistance: The five main factors include; The environment where the pipes are used depends greatly on many factors that range from; If the pipe is to be used in areas such as water or chemical environment or areas of extreme temperature, then the pipe must be highly corrosion resistant to ensure it lasts for a long period.
  • Strength and Durability: Depending on the load and pressure to be handled, the mechanical properties such as tensile strength and hardness should be checked. In particular, high pressure may require the use of robust materials such as stainless or carbon steel.
  • Cost: It is normally influenced by the budget since one has to compromise with the material that he or she is going to use. Aluminium, being the most common, can also be pricey but in the long run, it will prove costly to maintain, unlike stainless steel and copper. Whereas, aluminium and carbon steel are comparatively cheaper but may involve higher maintenance costs in the long term.
  • Installation and Maintenance: It will also be important to factor in the ease with which the systems can be installed, as well as whether they may require maintenance at some point or another. The easier it is to cut, weld or join materials, the lower the labour costs will be and the shorter the installation time. Furthermore, using pipes with the least amount of maintenance needed is also desirable because of the costs in the long run.
