Mechanical Properties

1.As we all know, the burr is one of the common phenomena occurring in metal cutting. Our company has professional pipe cutting machines for deburring. The saw blade is replaced on a regular basis, in order to make the better square cutting effect. Specifically,
①We adopts square cut( fast cutting) to make a pipe end treatment, no burrs, clean end;
②As a result of blunt edge treatment, round steel pipe looks like much thicker as per your specific requirements.
③We have advanced equipment and specific devices for an effective treatment of late processing of pipes.

2.Our pipes undergo a Chromic Acid passivation treatment for the surface of galvanized steel pipe. As a rule, hydrogen treatment and passivation treatment are the two major methods for the final effective painting treatment of galvanized pipe, in order to further improve the corrosion resistance of the zinc layer or maintain the original property of the coating. Furthermore, it also helps to prolong the durable years of the pipes. Generally speaking, our pipes can be used for at least 3 ~ 5 years, sometimes even up to 20 years. In that regard, there alsohas much to do with the specific environment in the actual applications.
