3/16 дюйма автоматическая тормозная система стальная труба bundy с покрытием

Bundy tube, sometimes called Bundy pipe, is type of double-walled low-carbon steel tube manufactured by rolling a copper-coated steel strip through 720 degrees and resistance brazing the overlapped seam in a process called Bundywelding. It may be zinc- or terne- coated for corrosion protection. It is used in automotive hydraulic brake lines in cars.

Burst Pressure:  110MPa min.

Made to SAE J527, ASTM A254.

Coated copper on both sides of the steel strip and brazed after coiled 720℃

PVF coated for longer time against corrosion.

Water-proof packing, using plastic film for inner package , and plastic woven bag for outside package,and then put them in the wooden box.
