The Red Thread IIA Fiberglass Pipe is a composite piping system designed for underground fuel handling applications. It is the first composite pipe to receive UL listing (UL 971) for this purpose. The system comprises primary and secondary pipe options, along with various fittings, and is intended for use with a range of fuels and fuel mixtures. Proper installation is critical to ensure long-term tank performance and prevent environmental contamination, necessitating comprehensive contractor training.
System Overview and UL Listing
The Red Thread IIA system is engineered for the safe and reliable conveyance of fuels. A key feature is its UL listing (UL 971), signifying that it has met specific safety standards for underground fuel handling. This listing applies to pipe sizes ranging from 2 to 4 inches for the primary pipe and 3 to 6 inches for the secondary pipe. The system’s design focuses on corrosion resistance and structural integrity, crucial for long-term performance in underground environments.
Red Thread IIA Primary Pipe Specifications
The primary pipe component of the Red Thread IIA system is designed for higher pressure applications. Its specifications, as detailed in the available documentation, are as follows:
- Size range: 2- to 4-in. UL listed
- Inner corrosion barrier: Resin-rich
- Pressure ratings: Up to 250 psig
- Construction: Filament wound with amine-cured epoxy resins and fiberglass roving
The filament winding construction process utilizes epoxy resins and fiberglass roving to create a robust and chemically resistant pipe structure. The resin-rich inner corrosion barrier provides an additional layer of protection against fuel-induced degradation.
Red Thread IIA Secondary Pipe Specifications
The secondary pipe option is intended for applications with lower pressure requirements. Its specifications include:
- Size range: 3- to 6-in. UL listed
- Inner corrosion barrier: Resin-rich
- Pressure ratings: Up to 50 psig
- Temperature range: Up to 150 °F (65 °C)
- Fittings: Threaded and bonded (TAB) or bell and spigot
Like the primary pipe, the secondary pipe features a resin-rich inner corrosion barrier. The available documentation specifies a maximum operating temperature of 150 °F (65 °C). Connections can be made using either threaded and bonded (TAB) fittings or bell and spigot connections.
Chemical Compatibility
The Red Thread IIA system is designed for compatibility with a variety of fuels and fuel-related products. The documentation explicitly lists the following chemical services as suitable for use with the system:
- Petroleum products
- Alcohols
- Alcohol-gasoline mixtures
- Ethanol
- Methanol
- MTBE
- Diesel exhaust fluid
This broad chemical compatibility makes the system adaptable to various fuel handling scenarios.
Fitting Options
The Red Thread IIA system supports multiple fitting styles to accommodate different installation requirements. These include:
- Threaded and bonded (TAB) fittings
- Bell and spigot fittings
The choice of fitting type may depend on factors such as pipe size, pressure requirements, and installation preferences. Specific data sheets are available for both primary and secondary fittings. Bonded sump entry fittings are also available, with accompanying instruction flyers.
Importance of Proper Installation
The provided documentation emphasizes the critical importance of proper installation procedures. Contractor training is highlighted as essential to ensure long-term tank performance and prevent potential issues such as tank failure, product release, and environmental contamination. Improper installation can compromise the integrity of the system and lead to costly repairs or environmental hazards.
