ASTM A254 Copper Alloy Bundy Tube for Vehicle parts and Refrigerator
TONG CHUANG GROUP is one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 30 years， we have accumulated a great many clients all around the world and TONG CHUANG products also won the great praise among the customers.
What is Bundy Tube?
Steel Bundy Tubing is double wall steel tube that has a copper coating to protect against the elements. Suits early model Holden， Ford， Chrysler， American Muscle cars as well as classic Hot Rods and many other types of vehicles.
Bundy tubing can be used for Brake lines， Fuel lines， Automatic gearbox return lines as well as other applications requiring high burst pressure resistant pipe. The product can be bent and flared to suit even the most complex braking system.

Features of Bundy Tube
1. The high-precision cold-rolled high-quality low-carbon steel strip and the superb precision rolling technology ensure the precision and good concentricity of the outer diameter and wall thickness of the pipe;
2. 360° along the pipe wall and welding of the joint surface to ensure that the Bondi pipe will not leak;
3. At the same time， the pipe has the characteristics of high blasting strength and high anti-vibration fatigue limit;
4. In the manufacturing process of Bondi tube， lubricating oil with low carbon content is used to make the inner surface extremely clean， and the inner surface residue is less than 0.05g/m2.
5. Because the Bondi tube is made of high-quality low-carbon steel， it is easy to bend and form， easy to weld， and easy to process various shapes of tube ends.
Packing Details
1. Wooden case.
2. Plastic bag
3. As customer's requirement
Applications
Air Condition or Refrigerator， Fluid Pipe， Automotive Parts.
Mainly used for oil pressure gauge pipes， fuel pipes， brake pipes and similar devices in the automobile industry， refrigeration industry， heater manufacturing industry， and can also be widely used to replace copper pipes to reduce the cost of use.
