Factory Production
Solid billets are inspected and cleared of surface defects, cut to the required length, centred on the perforated end of the billet, then sent to a heating furnace for heating and perforated on a perforating machine. 
In the perforation while constantly rotating and advancing, in the rollers and the role of the top head, the internal cavity of the billet gradually formed, called the gross tube. 
Then sent to the automatic tube rolling machine to continue rolling. Finally, the wall thickness is evenly adjusted by an equalizing machine, and the diameter is fixed by a sizing machine to meet the specifications.

Seamless Stainless Steel Pipe
The seamless stainless steel pipe is made of round bar, which is processed through "heat treatment", "pickling", "cold drawing", "cold rolling", "straightening" and other production processes without seams.
Its most important feature is that there are no welds and the thinner the wall thickness, the more expensive it is and the longer the production cycle.
Due to the excellent strong pressure resistance, corrosion resistance and high temperature resistance of stainless steel seamless pipe, its application environment is more extensive, and is now mostly used in petroleum, chemical, construction, marine, marine and other environments.
