Carbon Steel Copper Coated Bundy Tube For Automotive Hydraulic Brake Lines
Bundy tube is type of double-walled low-carbon steel tube manufactured by rolling a copper-coated steel strip through 720°F and resistance brazing the overlapped seam in a process called Bundywelding. It may be zinc coated for corrosion protection. It is primarily used in automotive hydraulic brake lines in cars. We can supply any type and diameter of Bundy Tube your requirement calls for.
Bundy Tube
Bundy tube, also known as copper-plated iron pipe, is a thin steel tube with a diameter of 4.6-10.6, this kind of tube (pipe) main feature is to solve the problem of short period of iron pipe placement, easy to rust, mainly used to make water tubular heating elements, or embedded heat conduction, such as bread machine heater tubes, electric irons heaters, pizza pan heaters, etc.
The Bundy tube have the advantage of high quality, durable and stable, high Resistant to vibration cracking and high pressure, Good processability, High dimensional accuracy and good surface quality and long service life time.
It covers single-wall, double-wall, copper-brazed steel tubing, zinc-coated steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The tubing is available in either of two types, single strip or double strip. It is delivered in straight length or coil type.
Electro-welded Single Wall Steel Tubing
Single wall steel tubing is the most common type of tubing used in household refrigeration applications. Bundy single wall tubing is manufactured by continuously forming a single low carbon steel strip into a tubular shape and welding the adjoining edges using a high frequency induction welding process. Through strict process controls, the internal weld bead is held to a minimum and all external flashing is removed. Corrosion resistant coatings are applied in-line to assure uniform coverage.
