Pressure pipes are vital components for construction in almost every industry, transporting fluids and gases across both long and short distances and both below and above ground. However, like any other construction element, there are a variety of differing types of pressure pipe for different scenarios. Of course, countless different shapes and diameters are available, but the most important differences largely pertain to the material the pipes are made out of. So — what are the best materials that are used to construct pressure pipes, and why exactly should you prioritise them over cheaper materials?
Perhaps the most versatile and durable of the materials commonly used for piping, steel is a great option if you'd like to just bury your piping and largely forget about it. Of course, it will still require some maintenance over long periods of time, and it will still need to be inspected for external corrosion and leakages, but you'll find that it's not nearly as problematic as other, cheaper metals. However, you will pay for the privilege of this greater durability — and you'll need highly trained contractors to install steel pipes, too.
When people refer to concrete pressure piping, it's something of a misnomer; in fact, what is referred to as concrete piping is simply steel that has been coated. More often than not, it is coated both on the interior and the exterior of the pipe, protecting it from both its high-pressured contents and external rust and degradation. Perhaps predictably, this is more expensive and specialised than non-treated steel, but you'll save on your maintenance costs in the long run over cheaper materials.
Provided that the liquid or gas you're transporting is not corrosive or too high pressured for each individual material, it is perfectly possible to 'mix and match' steel and concrete pipes and their components in one individual system — and other metals, too, if you have opted for cheaper materials. It's not preferable, as it may complicate your maintenance requirements. However, in order to save a great deal of money, lower shipping costs or achieve a quick repair, it is certainly an option worth considering.
In essence, what you're paying for is reduced maintenance costs in the future. That may upset your balance books in the short term, but it's a smart move in the long run. As such, you should go for the highest quality option you can afford and reap the benefits later.
