 Precision profiled steel pipe

Compared with precision profiled steel pipe, the precision of precision profiled seamless steel pipe is better than that of cold drawn profiled steel pipe. Generally, precision profiled steel pipe is manufactured with mandrel inside and abrasive tools outside. In this way, the precision and ovality of precision profiled steel pipe manufactured are better, and cold drawn profiled steel pipe is the simplest manufacturing method, After the cold drawing of abrasive tools, there is no mandrel, so the precision of cold drawn profiled seamless steel pipe made in this way is worse.

The price of precision special-shaped steel pipe is much higher than that of ordinary cold-drawn special-shaped steel pipe. The precision special-shaped steel pipe is generally used in the fields of precision machinery, automobile accessories, precision processing and aviation. In this way, the special-shaped steel pipe is more advantageous, and the processing is more convenient. However, the ordinary hexagonal steel pipe and octagonal steel pipe are selected for the general mechanical processing and manufacturing, Cold drawing special-shaped steel pipe, the price is cheaper.
