Wholesale Rolling Bundy Tube Copper Pipe for Fridge Coiling air Conditioner Tube Suppliers, Factories

Material: Steel tube, Copper

Product Description

Character

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:

1
High Precision

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.

2
High Strength

Bundy tubes have high explosive strength, high anti vibration fatigue limit, and can work stably in high-pressure and vibration environments.

3
Good Processing Performance

Bundy tubes are easy to bend, weld, and process with various shapes of pipe ends, suitable for various complex processing needs.

4
Internal Surface Cleaning

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.

5
Corrosion Resistance

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.

Application

Automotive Industry

Inside automobiles, Bundy tubes are commonly used materials for oil pressure gauge pipelines, fuel pipelines, and brake pipelines. They reliably transmit oil pressure signals, deliver fuel safely, and ensure the stable transmission of brake fluid for responsive braking.

Refrigeration Industry

In refrigeration equipment such as refrigerators, Bundy tubes serve as key pipelines for transporting liquids and gases. They carry refrigerants through the compressor, condenser, and evaporator loop to achieve refrigeration effects.

Heater Manufacturing

Bundy tubes are utilized for oil pressure gauge pipelines and related pressure-transmitting instruments in heater systems, guaranteeing accurate pressure display and facilitating safe operation monitoring.

Frequently Asked Questions

What are the main advantages of Bundy tubes?
Bundy tubes are highly valued for their high precision, excellent strength, superior corrosion resistance, and outstanding processing performance. Their double-layer structure allows them to operate reliably under high pressure and vibration.
How are Bundy tubes manufactured?
Bundy tubes are manufactured by rolling, welding, and galvanizing cold-rolled low-carbon steel sheets. This creates a double-layer structure with high concentricity and uniform wall thickness.
Are Bundy tubes easy to bend and shape?
Yes, Bundy tubes exhibit excellent processing characteristics. They are highly flexible and easy to bend, weld, and fit with different pipe end configurations, making them ideal for complex routing systems.
What is the level of internal cleanliness of Bundy tubes?
Bundy tubes are manufactured using low-carbon content lubricating oils to maintain a clean interior. The internal surface residue is kept extremely low, at less than 0.05g/m³, which prevents system contamination.
What anti-corrosion coatings can be applied to Bundy tubes?
To enhance corrosion resistance, the outer surface of Bundy tubes can be galvanized or coated with advanced protective materials, including PVF, aluminum-rich coatings (such as GALFAN), and nylon.
In which industries are Bundy tubes most commonly applied?
They are widely used in the automotive industry (for brake, fuel, and oil pressure lines), the refrigeration industry (for carrying refrigerants in cooling cycles), and in the heater manufacturing industry for safe fluid and gas transmission.
