The fiberglass rod production process


The fiberglass rod can be used in any new applications or replace existing applications, which are exposed to corrosive environments. The application can be found in all types of industries such as: offshore and onshore, entertainment, food, public facilities, power plants, e-government performance, electrical, oil and gas, pollution control, chemical, water/waste treatment and marine.

The fiberglass rod production process

Fiberglass rod are tubular FRP products processed by special processing techniques using glass fiber and thermosetting resin. They are recognized by many industries because of their special properties that metal products do not have, and are increasingly used in a variety of applications. In the industry, we will now briefly introduce some knowledge related to FRP round bars.


  1. According to the production process, FRP rods are divided into winding pipes, which are widely used in pipelines. The advantage is high transverse strength, but the disadvantage is low longitudinal strength. Generally, continuous production is not possible, and the product is fixed to length. The cloth-wrapped tube is lightweight and high-strength, with equal strength in the vertical and horizontal directions, and can produce thin-walled tubes. The disadvantages are low production efficiency, many procedures, large amount of personnel, and low quality stability coefficient.


  1. Pultrusion process—The production process is relatively simple, the vertical direction is stronger than the horizontal direction, and a reinforcement layer can be added to increase the horizontal strength. The surface is smooth and continuous production is possible. The products can be customized according to customer needs. The production efficiency is high, but the shortcomings are big. The production of size products is difficult, the machine and process requirements are high, and the production of thin-walled pipes is difficult. Most of the small and medium-sized pipes are produced, and the application prospects are broad.


  1. According to the shape, the FRP rods are mainly round tubes, as well as FRP square tubes, FRP rectangular tubes, FRP porous tubes, various special-shaped tubes and other products. Various cross-section fiberglass tubes can be customized according to customer requirements.


  1. According to the raw materials, the raw materials used in many FRP round rod tubes are polyester resin, anti-corrosion vinyl ester resin, and glass fiber tubes made of epoxy, phenolic, polyurethane and other raw materials, using different raw materials Given the different physical, mechanical and chemical properties of the glass fiber tube, we can customize the production and processing for the customer according to the customer’s specific use environment and requirements to meet customer requirements. Access to documents, more convenient to use.
