The main features of Bundy tubes include high precision, high strength, good processing performance, and corrosion resistance. Bundy tubes are made by rolling, welding, and galvanizing cold-rolled steel sheets. Their double-layer structure and special manufacturing process give them unique advantages:
Bundy tubes use high-precision cold-rolled high-quality low-carbon steel strips and exquisite precision rolling technology to ensure the precision of pipe outer diameter and wall thickness, as well as good concentricity.
Bundy tubes have high explosive strength, high anti vibration fatigue limit, and can work stably in high-pressure and vibration environments.
Bundy tubes are easy to bend, weld, and process with various shapes of pipe ends, suitable for various complex processing needs.
lubricating oil with low carbon content is used in the manufacturing process to make the internal surface extremely clean, and the residue on the internal surface is less than 0.05g/m³.
The surface of Bundy tubes can be galvanized or coated with other anti-corrosion materials, such as PVF, aluminum rich coating (GALFAN pipes), nylon, etc., to further enhance their corrosion resistance.
| Body Diameter (mm) | Thickness (mm) |
|---|---|
| 4 | 0.5-0.6 |
| 4.76 | 0.5-0.65 |
| 6 | 0.5-0.65 |
| 6.35 | 0.5-0.65 |
| 8 | 0.5-0.7 |
Inside automobiles, Bundy tubes are commonly used materials for oil pressure gauge pipelines, fuel pipelines, and brake pipelines. For example, oil pressure gauge pipelines use Bundy tubes to transmit oil pressure signals, ensuring drivers have real-time knowledge of the engine oil pressure status; fuel pipelines rely on them to safely deliver fuel to the engine; and brake pipelines utilize their properties to ensure the stable transmission of brake fluid, enabling reliable braking.
In refrigeration equipment such as refrigerators, Bundy tubes serve as pipelines for transporting liquids and gases. In the refrigeration cycle system, they are responsible for transporting refrigerants, allowing the refrigerants to circulate among components such as compressors, condensers, and evaporators, thus achieving the refrigeration effect.
Bundy tubes are used for various oil pressure gauge pipelines and similar devices. During the operation of heaters, Bundy tubes can accurately transmit pressure-related media, assisting instruments such as oil pressure gauges to accurately display pressure values and ensuring the stable operation and safety monitoring of heaters.
Bundy tubes are manufactured by rolling, welding, and galvanizing cold-rolled low-carbon steel sheets. They feature a unique double-layer wall structure that provides excellent strength and durability.
Bundy tubes offer exceptionally high explosive strength and a high vibration fatigue limit. This allows them to perform reliably under the constant pressure and vibration of automotive brake and fuel line applications.
The surface of Bundy tubes can be treated with various protective coatings, including galvanization, PVF, nylon, or aluminum-rich coatings (such as GALFAN), to prevent rust and degradation in harsh environments.
During production, low-carbon lubricating oils are used to keep the inner surface clean. The internal residue is strictly maintained below 0.05g/m³, which is crucial for refrigeration and precision instrument systems.
Yes, Bundy tubes exhibit excellent processing characteristics. They can be easily bent, welded, and shaped at the ends without compromising their structural integrity, making them highly versatile for complex layouts.
Standard Bundy tubes are available in body outer diameters of 4mm, 4.76mm, 6mm, 6.35mm, and 8mm. The corresponding wall thicknesses range from 0.5mm to 0.7mm, depending on the specific diameter and application requirements.
