シームレス鋼管 is made by heating solid steel billets and perforating them into hollow tubes, which are then processed by rolling or stretching. Seamless steel pipe is particularly strong and can withstand high pressure and temperature because they have no welds.
シームレス鋼管 can be produced as per ASTM/ASME or EN standard. Different standard have the difference out diameter and thickness
