Why Choose GRP Pipes?

This article will provide you with information about GRP pipelines. It is easier to reach your goals by reading the article carefully and putting yourself in the shoes of the end-user to understand their concerns and fears. There are many reasons why GRP pipeline solutions are replacing traditional pipelines in many countries, so keep this relatively new product in mind when evaluating new pipeline projects or planning to retrofit pipelines.

At the same time, engineers involved in specifying GRP piping should have a clear understanding of the nature and characteristics of the pipeline.

You probably already know the main advantages of GRP piping, but let's mention them quickly anyway.

GRP pipes have higher corrosion resistance than cast iron and carbon steel pipes because of the inert nature of the materials they are composed of. GRP pipes with a design life of 50-60 years are not uncommon. Today, some manufacturers even estimate their service life to be over 100 years. GRP pipes can be designed to be corrosion-resistant inside and out. In fact, with the help of an internal and external barrier, and using the correct resin barrier, pipes can withstand a wide range of corrosive environments.

Due to its composite construction, GRP pipes can be designed to fully meet project requirements, resulting in cost savings. Another advantage of GRP pipes is pressure absorption: they are designed to absorb up to 40% of surge pressure without the need for additional pressure ratings.

GRP pipes also have natural damping properties. Fatigue durability and strength-to-weight ratio are key attributes associated with replacement costs and the ability to design lightweight pipes.

Minimal frictional losses due to its smooth inner surface, and the maintenance of this property throughout its service life.

The last but not least feature of GRP pipes is their low maintenance cost, due to the fact that they are not subject to corrosion like metal pipes.

Decision-makers must also consider the special characteristics of GRP pipelines

Despite these advantages, decision-makers must also consider the special characteristics of GRP pipelines, which means that

In order to properly calculate the total investment cost, investors must also consider the installation, erection, and maintenance costs to be able to compare them with other materials. If only the initial costs are assessed, the project figures will be unrealistic.

GRP pipelines are designed to be performance-based. In other words, investors must be careful in determining project requirements and true operating conditions before sharing information with pipe suppliers.

Composite pipe manufacturing should require investors to comply with specific directives to ensure the long-term performance of the pipe.

It is also important for engineers to understand the limitations of GRP pipes, depending on the technology used to manufacture them. In recent years, I have noticed that some projects have been influenced by the strong marketing and miraculous promises made by some pipe manufacturers, leading to misuse of the product.

For example, the performance of continuous filament wound pipe is very high in some applications and lower in others, as is the case with discontinuous filament wound or centrifugally cast GRP pipe.
