FRP pipes do have excellent oil resistance, primarily due to their composite structure, which uses glass fiber as reinforcement and a synthetic resin as a matrix. This property effectively resists oil corrosion when transporting media such as crude oil and refined oil.

The following table provides a quick overview of FRP pipe oil resistance and leak handling:

4. Features/Aspects	illustrate
   Oil resistance	FRP pipes have good oil resistance and can resist the erosion of crude oil, refined oil and other oil products.
   Leakage treatment methods	This includes plugging leaks without stopping production (such as using fiberglass repair materials), repairs after production stops (such as replacing seals or pipe sections), and the use of special emergency repair parts (such as conversion joints).
   Advantages of using emergency repair parts	Rapid resumption of operation, ensuring pipeline material consistency (good for corrosion prevention), safe and reliable, and highly applicable.

    

What to do if a FRP oil-resistant pipe leaks?

When a FRP oil-resistant pipe leaks, different treatment methods can be used depending on the leak type, process pressure, and safety requirements:

1. Minor leaks or where production suspension is not permitted (normal pressure/low pressure): For small holes or cracks, flameless repair techniques can be considered. For example, specialized FRP repair materials (such as resin putty or fiberglass cloth) are applied to the leak site, wrapping and curing them in multiple layers. After cleaning the leak surface, resin putty and fiberglass cloth are applied layer by layer, wrapping and curing them. This method is typically used in low-pressure applications.

2. Repairs after a planned production shutdown or for large leaks: The pipeline must be shut down, pressure released, and isolated before treatment. For leaks at seals, tighten the flange bolts or replace the gaskets. For leaks at joints, tighten them or apply sealant. For severe pipe damage, cut away the damaged section and connect a new pipe section using a conversion joint.
3. Use specialized repair parts: For FRP pipes, especially leaks at threaded connections, using repair pipes specifically designed for FRP pipes (such as those with Y-rings and left-right twist clamps) or conversion joints is generally the fastest and most reliable option.

Advantages of Using Oil-Resistant Repair Parts

When FRP pipes leak, using specialized oil-resistant repair parts (such as repair pipes and conversion joints) offers the following advantages:

Quickly restore operations and reduce downtime and losses: Repair parts are often designed for quick on-site installation, significantly shortening downtime and minimizing economic losses.

Ensure pipeline material consistency and corrosion resistance: Professional FRP repair parts ensure consistent, fully FRP material throughout the pipeline, fully utilizing the corrosion resistance of FRP and preventing the formation of new corrosion vulnerabilities. Safe, reliable, and easy to use: Many repair kits are designed to eliminate the need for hot work, reducing operational risks in oil and gas environments. For example, some repair pipes utilize threaded connections and sealing rings for easy operation.

Versatile: Repair kits are available for various connection methods (such as threaded and socket), adapting to various leak scenarios on site.

The following are Baoshuo brand oil-resistant leak repair clamps, high-temperature leak repair clamps, acid- and alkali-resistant leak repair clamps, stainless steel leak repair clamps, high-pressure leak repair clamps, and large-diameter leak repair clamps.

The housing is typically made of metals such as ductile iron and carbon steel, which are corrosion-resistant and high-strength. It can last the same life as the original pipe, eliminating the need for frequent repairs. Baoshuo brand carbon steel half joints are available in a variety of rubber materials, including NBR, EPDM, FKM, and silicone rubber. The half joint body is available in Q235 carbon steel and 304 and 316L stainless steel.

Maintenance and Prevention Recommendations

1. Regular Inspections: Regularly inspect pipelines, especially joints, connections (where leaks are likely to occur), flanges, elbows, and support areas for abnormalities.
2. Strictly Control Operating Parameters: Ensure that parameters such as temperature and pressure are within the design range to avoid operation at excessive temperatures or pressures. For example, flexible composite pipes experience reduced pressure-bearing capacity at high temperatures, requiring special attention.
3. Standardized Installation and Construction: High-quality installation is key to preventing leaks. Ensure that threaded connections are tightened to the correct torque and seal properly to reduce installation stress.

4. Consider environmental factors: For buried pipelines, pay attention to soil corrosiveness and external force influences; for ground pipelines, pay attention to protection against mechanical impact and climate aging.
