ASTM A269 S31254 Manufacturing Process

SS 254 SMO Seamless pipe:
Seamless pipe has no welds. Seamless pipe is made by hot rolling or cold rolling. It can withstand higher pressure. The cost is relatively high. It is particularly suitable for use in extreme environments (such as seawater, chemical media, etc.).

SS 254 SMO Welded pipe:
Welded pipe uses ready-made steel plates or steel strips to form pipes through welding. The advantage is that it produces larger diameter pipes, low prices and short delivery times.
