Naadloze stalen pijp wordt gemaakt door vaste stalen knuppels te verwarmen en ze te perforeren in holle buizen, die vervolgens worden verwerkt door rollen of strekken.
Naadloze stalen pijp can be produced as per ASTM/ASME or EN standard. Different standard have the difference out diameter and thickness
