Tubes of 12.7x1mm were shipped from our local factory, cut in 5.8 meter length, packed in steel case, by heavy trucks to Shanghai. The tubes were made to Indian standard of copper brazed steel tubing IS8119 Class I, double wall structure. They shall be used further to manufacture tube parts for railway hydraulic systems.
Tubes are finished with no extra surface finish, just the original copper coating of the Bundy welding process.
