Product Description

ASTM A254-97 BHG1 4.76*0.6mm Double Wall Brazed Steel Tube made from Low Carbon Steel Strip

 

Changzhou Joyruns' Copper-Brazed Steel Tubing conforms to the ASTM A254-97 Standard Specification. It can be used for fuel lines, brake lines, oil lines of Automotive uses, cooling units of refrigeration uses and stove industries. etc. It is made by rolling steel strips into the form of tubing and subsequently copper brazing in a reducing atmosphere. After a variety of analyses, like heat analysis and product analysis, and through tension tensile strength, flattening, expansion, bending and pressure-proof test to ensure the quality.

 

Double Walled Steel Tubing is a steel tube for pressure piping, which is manufactured from electrolytic copper-coated steel strips (both surfaces). The strip is wound into a continuous tubular with a double-layered wall and then copper brazed in a special furnace using the coated copper as filler metal.

 

Double Wall Brazed Steel Tube possesses higher withstanding pressure and higher vibration fatigue strength. Furthermore, the tube is also equipped with superior properties such as solderability, traceability, bendability, and workability in end terminal preparation. As a pressure tubing material with extensive reliability and good processing characteristics, this tube is used for several purposes, such as brake tubing, the power steering on vehicles, and many more.
