API 5L GR.B SSAW -Rohr bezieht sich auf eine Art Stahlrohr, die den Spezifikationen der API 5L -Grad B entspricht und mit dem SSAW -Verfahren (Spiral Submerged ARC Welding) hergestellt wird.
API 5L Grad B ist eine der häufig verwendeten in API 5L angegebenen Noten. Es hat eine minimale Streckgrenze von 42.000 psi (290 MPa) und eine Mindestfestigkeit von 60.000 psi (415 MPa). Die Rohre der Klasse B sind für Anwendungen geeignet, bei denen sich der Fokus hauptsächlich auf den mechanischen Eigenschaften des Rohrs befindet.
API 5L GR.B SSAW -Rohre werden während der Herstellung strenger Qualitätskontrollmaßnahmen unterzogen, um die Einhaltung der angegebenen API 5L -Anforderungen zu gewährleisten. Dies umfasst Tests auf Abmessungen, mechanische Eigenschaften, chemische Zusammensetzung, nicht zerstörerische Tests und visuelle Inspektion.
API 5L GR.B SSAW -Rohre werden üblicherweise in verschiedenen Pipeline -Projekten für den Transport von Öl, Gas und Wasser über lange Strecken verwendet. Sie sind so konzipiert, dass sie die spezifischen Anforderungen der Anwendung erfüllen und zuverlässigen und effizienten Flüssigkeitstransports gewährleisten.

Der Prozess des SSAW -Stahlrohrs :
Stahlspulen → Strahlenmaterialtest → Lieferung → Plattenabschneiden und Schweißen → Kreisscherungskantenmahlen → Formierung → Innen-Auto-Abschweibe → Außen Auto-Abmeldung → Online-Ultraschallinspektion → Schneiden fester Länge → Visualinspektion für Außensamen → Visusl-Inspektion für innerlich Naht → Röntgeninspektion für Schweißnähte → sogar End- und Ende-Schloss → Hydrostatischer Test → Ultraschallinspektion → Endproduktinspektion → Markierung → Aufbewahren
