Strategies for Dealing with Issues in Fiberglass Reinforced Plastic (FRP) Pipes
Release time:
2022/05/20
Fiberglass reinforced plastic (FRP) pipes are non-metallic pipes made from resin (food-grade resin for drinking water), fiberglass, and quartz sand, produced using special processes. As a composite material with excellent overall performance, FRP pipes are widely used in more complex industrial environments due to their unique advantages. FRP sand-coated pipes have strong corrosion resistance, smooth inner surfaces, low energy consumption, long service life (over 50 years), convenient transportation and installation, low maintenance costs, and overall low costs. They have been widely applied in industries such as electricity, chemicals, papermaking, urban water supply and drainage, factory wastewater treatment, seawater desalination, and natural gas transportation. Many factories have encountered safety hazards due to improper material selection, leading to significant expenses for repairs or replacements. Therefore, the quality of materials plays a decisive role in the development of factories and even companies. The main issues with FRP pipes include delamination caused by: (1) old tape, (2) tape that is too small or uneven, (3) low temperature of the hot roller, preventing the resin from melting properly, (4) low tension of the bonding fabric, and (5) excessive amounts of degreaser that prevent the core fabric from being dyed. Solutions for FRP pipes include: (1) ensuring that the adhesive content of the tape and soluble resin meets quality requirements, (2) adjusting the temperature of the hot roller so that the tape passes through it, making the tape soft and viscous, and ensuring the core is firm, (3) adjusting the tension of the tape, and (4) avoiding the use of oily desulfurizers or reducing their quantity. For the foaming of the inner wall, it is important to pay attention to operations and ensure that the guiding fabric adheres to the core. The main reason for post-curing foaming is that the volatile content in the tape is too high, while the rolling temperature is low and the rolling speed is fast, preventing volatile substances in the tape from evaporating in time and remaining in the pipe. When the pipe is heated and cured, the residual volatile substances expand, causing foaming. The solution is to control the volatile content of the tape, appropriately increase the winding temperature, and reduce the winding speed. The wrinkling of the pipe after curing is caused by a high content of adhesive in the adhesive. The solution is to reduce the tape content and lower the rolling temperature. The causes of voltage resistance issues are: (1) insufficient tape tension, low rolling temperature, or fast rolling speed, leading to poor adhesion between fabrics and excessive residual volatiles in the pipe, and (2) incomplete maintenance of the pipe. Solutions include: (1) increasing tape tension, raising rolling temperature, or slowing down the rolling speed, and (2) adjusting the curing process to ensure the hose is fully cured. 1. Due to its low density and lightweight, FRP pipes are prone to floating in areas with high groundwater levels. Therefore, it is necessary to consider anti-floating measures for urban docks or rainwater runoff dredging. 2. In the construction of T-joint openings and repairs of pipe cracks in FRP pipe installation, the resin and fiber cloth used in construction need to cure within 78 hours, similar to the complete conditions in factories. However, on-site construction and maintenance often struggle to meet this requirement. 3. Existing underground pipeline detection equipment is mainly used for detecting metal pipes, while non-metallic pipeline detection equipment is expensive and cannot detect buried FRP pipes. Other subsequent construction units are prone to excavating and damaging the pipes during construction. Guangxi Fiberglass Products Co., Ltd. is a professional manufacturer of FRP pipes, and its products are well-received by users. All products are designed, produced, and inspected in strict accordance with relevant national standards. We welcome inquiries.

Main existing
FRP pipeissues: Delamination of FRP pipes:(1) The tape is too old, (2) The tape is too small or uneven, (3) The temperature of the hot roller is too low, and the resin does not melt well. The tape does not adhere well to the mold; (4) The tension of the bonding fabric is low, (5) The amount of degreaser is too large, preventing the core fabric from being dyed.Solutions for FRP pipes:
(1) The adhesive content of the tape and soluble resin should meet quality requirements: (2) Adjust the temperature of the hot roller so that the tape passes through it, making the tape soft, viscous, and the core firm; (3) Adjust the tension of the tape; (4) Do not use oily desulfurizers or reduce their usage.

In the construction of repairing the three-way openings and cracks of FRP pipes, the resin and fiber cloth used in the construction need to cure within 78 hours, similar to the complete situation in the factory. However, on-site construction and maintenance often struggle to meet this requirement. 3.
