At the same time, its excellent weather resistance allows it to provide a long service life outdoors.
FRP pultruded tubing can be used as a protective and isolating structure for the electrical field. It can effectively prevent accidents caused by electrical leakage and is suitable for power plants, outdoor substations, etc., where humid conditions exist and safety requirements are stringent.
The petrochemical industry requires materials with excellent corrosion resistance and chemical stability. Compared to metal pipes, FRP pultruded tubes are lightweight and can be used for long periods in salt spray, acidic or alkaline environments, without corrosion or rust. They are usually used as platforms, guardrails, and many other structures in this field.
In transportation, FRP pultruded tube mainly plays the role of supporting structure and protecting the traffic. It can be used as a guardrail on highways or as a support structure for bridges. Thanks to its weather resistance and robustness, it supports long term use in outdoor conditions.
When it comes to choosing between FRP pultruded tubes and steel tubes, you need to consider the specific application. Generally speaking, steel tubes are heavier and more prone to rust than FRP pultruded tubes. It is generally suitable for applications that require welding and heavier loads. On the other hand, FRP tubes are more suitable for applications that require lightweighting, insulation, and low maintenance performance.
Generally speaking, o-phenyl/m-phenyl resins are suitable for salt environments, and their use temperature ranges from minus fifty to fifty-two degrees Celsius (o-phenyl resins) and above (m-phenyl resins), they are suitable for most industrial environments.
While vinyl resin has better corrosion resistance and can adapt to harsh acid and alkali environments, it is suitable for marine, chemical and other fields. Phenolic resins perform better in terms of flame retardancy and acid resistance, with a range of up to 180 degrees Celsius, making them suitable for buildings or applications with stringent fire protection requirements.
Yes, FRP pultruded tube is a material that supports long term use. It has inherently good mechanical properties and corrosion resistance, requiring little maintenance for outdoor use. It’s service life of more than a decade or even decades.
What Is a FRP Pultruded Tube?
Fiberglass reinforced plastic (FRP) is a material made of synthetic resin as the base material and glass fiber, or other materials acting as the reinforcing material. FRP pultruded tube is a kind of tube produced by pultrusion molding and has various shapes such as rectangle, circle, irregular shapes, etc.
It has the characteristics of excellent structural strength and light weight, and can be used as a structural support for the building. Now it is widely used in today’s construction, industry and many other fields.
How Is FRP Pultruded Tube Produced?
Raw Material Preparation
First, we will prepare the raw materials needed for FRP pultrusion molding, which generally include glass fiber, resin and necessary additives. In this process, we select the best quality materials for subsequent production through our raw material testing laboratory. So that the quality of the FRP pultruded pipe is guaranteed from the source.
Mold Manufacturing
The production of FRP pultruded pipes is also dependent on the plasticity of the mold. Therefore, we will produce molds through advanced processing technology to ensure that the surface of the mold is smooth and the dimensions are accurate.
Pultrusion Process
When entering the formal production stage, we will first haul the fiber yarn to the resin to moisten. The fiber yarns are then passed through a mold of a certain cross-sectional shape, where they are pressed, heated and cured against the FRP pipe. Finally, the finished product is pulled through the pultrusion system to get the complete and strong FRP pipe you need.
In the actual pultrusion molding process, we need to have precise control of the haul-off speed and temperature to ensure that the molded FRP pultruded pipe has excellent performance and stable quality.
What Are The Advantages Of FRP Pultruded Tube?
High Strength
The glass fiber itself is a high strength material, and with the good toughness of the resin, the FRP material therefore has good mechanical properties. After the pultruded process, FRP pultruded fiberglass tubes also have a high strength property. It can distribute the pressure better along its length, so that it does not break or shatter easily.
Lighter Weight
Pultruded FRP has a lower density and therefore weighs much less than steel or aluminum of the same volume. In addition, FRP pultruded pipe is mostly hollow, which further reduces its weight per unit volume. It is easy to handle and install, and when used as a structural support for buildings, FRP pultruded tubes can effectively reduce the dead weight of the building. In logistics transportation, it can effectively reduce the energy consumption brought about by traffic.
Corrosion Resistance
Resin is a corrosion resistant material. Unlike metal, it will not rust in a salt spray environment or have chemical reactions in a corrosive environment. In FRP pultruded pipe, the resin will also completely encapsulate the glass fiber to prevent it from chemical corrosion, so it is widely used in marine, chemical and other applications where corrosive environments exist.
Electrically Isolated
Both glass fiber and resin are non-conductive materials. Therefore, FRP pultruded tubes can be used to reduce the risk of electrical leakage or shock. It is often used in industrial and architectural applications where electrical isolation is required, either as protective equipment or as electrical support structures, ensuring better safety and protecting the operators during daily use.

Tips To Select The Best FRP Pultruded Tubes For You
Consider The Environment Of Applications
Before choosing the right FRP pultruded tube , you need to confirm the nature of the specific environment in which it will be used. For example, you should consider the temperature and humidity, the degree of corrosion as well as the intensity of UV rays.
Different resin compositions are resistant to different ambient temperatures and corrosive properties. By choosing the right FRP pultruded tube with the right composition according to the characteristics of the environment, you will be able to more fully use its advantages and performance. Thus you can avoid the effect of mismatch between the material and the environment, which will cause a significant reduction in the effectiveness of the use and the life of the pipe.
Confirm The Fire Rating
Fire rating is also an important reference factor when selecting FRP pultruded tubes. This is critical for compliance with your plant’s operations and for safety in the long term. You need to be sure that the FRP pultruded tube meets the fire protection requirements in your area. The most reliable way to determine this is to make sure that the product you choose has passed the ASTM flame retardant test, which is the most intuitive and authoritative criterion.
Know about The Factory’s Quality Management System
The good performance of FRP pultruded tubes also depends on the quality control carried out by the factory during its production. It is important for you to find out whether there is any testing of raw materials and strict control of process parameters, as well as whether the FRP pultruded pipe you buy will be tested before it leaves the factory. These will help you determine whether the factory is responsible and whether you will receive a product that will last long enough.
