Bundy tubes are fully monitored during the tube fabrication, and also gone through a series of inspections to make sure they are safe and reliable for hydraulic uses.

Test and inspection items specified in standards of different countries are generally the same or very similar. We manufacture the tubes and issue test reports as per Chinese standard if no other particular requirement comes from buyers.

One thing to note is that the material listed in those standards are slightly different among countries. Low carbon steel is required commonly, but the chemical composition of the material varies, especially for carbon. In most of these countries, the steel grade exists already in their steel industry. In China, there is equivalent steel grades, but we specially developed a steel grade, BHG2, that is much more suitable for the double wall brazed steel tubing manufacture, perfect mechanical properties for the tube forming and also for the final tubes.
