ASTM A270 stainless steel seamless tubes are used for high purity products and equipment in the food, beverage, pharmaceutical, and biotech industries where cleanliness and purity are essential. These tubes are made from austenitic stainless steels like 304 and 316L, which are non-magnetic and have high corrosion resistance.
Die ASTM A270-Norm spezifiziert die Anforderungen an nahtlose und geschweißte austenitische und ferritisch/austenitische Sanitärrohre aus nichtrostendem Stahl, die zur Verwendung in der Milch- und Lebensmittelindustrie bestimmt sind und eine besondere Oberflächenbeschaffenheit aufweisen. Nahtlose Rohre aus Edelstahl ASTM A270 werden im Kaltziehverfahren oder im Pilgerschrittverfahren hergestellt.
Die Rohre sind in verschiedenen Größen, Wandstärken und Oberflächenausführungen wie blank geglüht, mechanisch poliert und elektropoliert erhältlich. Die elektropolierte Oberfläche bietet eine glatte und glänzende Oberfläche, die leichter zu reinigen ist und das Wachstum von Bakterien verhindert.
Nahtlose Rohre aus Edelstahl ASTM A270 werden auch auf ihre chemische Zusammensetzung, ihre mechanischen Eigenschaften und ihre Korrosionsbeständigkeit geprüft. Die Rohre müssen die für diese Eigenschaften festgelegten Anforderungen erfüllen, um sicherzustellen, dass sie für den Einsatz in Lebensmittel- und Pharmaanwendungen geeignet sind.
Zusammengefasst, Nahtlose Rohre aus Edelstahl ASTM A270 sind ein wichtiger Bestandteil bei der Herstellung von hochreinen Produkten und Anlagen in der Lebensmittel-, Getränke-, Pharma- und Biotech-Industrie. Sie werden aus nichtmagnetischem austenitischem Edelstahl hergestellt, haben eine hohe Korrosionsbeständigkeit und sind in verschiedenen Größen und Ausführungen erhältlich, um spezifische Anwendungsanforderungen zu erfüllen.
ASTM A270 ist eine Standardspezifikation für nahtlose und geschweißte Sanitärrohre aus austenitischem und ferritischem/austenitischem Edelstahl, die für die Verwendung in der Milch- und Lebensmittelindustrie sowie für andere industrielle Anwendungen, einschließlich der chemischen und pharmazeutischen Industrie, vorgesehen sind. Die ASTM A270-Spezifikation gilt für nahtlose, geschweißte und stark kaltverformte Sanitärrohre aus austenitischem und ferritischem/austenitischem Edelstahl, die für den Einsatz in der Molkerei- und Lebensmittelindustrie sowie für andere industrielle Anwendungen bestimmt sind.
Die ASTM A270 Nahtloses Rohr aus Edelstahl wird in der Regel in chemischen Maschinen eingesetzt, wo hohe Korrosionsbeständigkeit und Festigkeit erforderlich sind. Das nahtlose Rohr verfügt über hervorragende chemische und mechanische Eigenschaften und ist daher für den Einsatz in rauen Umgebungen geeignet. Das ASTM A270 Nahtloses Rohr aus Edelstahl wird aus austenitischem rostfreiem Stahl hergestellt und ist in verschiedenen Größen, Dicken und Typen erhältlich.
Einige gängige Arten von Nahtlose Rohre aus Edelstahl ASTM A270 umfassen:
1. Typ 304/304L: Dies ist das am häufigsten verwendete nahtlose Edelstahlrohr, das für die meisten Anwendungen in der chemischen Industrie geeignet ist.
2. Typ 316/316L: Diese Art von nahtlosem Edelstahlrohr ist äußerst korrosionsbeständig und eignet sich ideal für den Einsatz in rauen Umgebungen.
3. Typ 321: Diese Art von nahtlosem Edelstahlrohr enthält Titan, das für zusätzliche Festigkeit und Korrosionsbeständigkeit sorgt.
Zusammenfassend lässt sich sagen, dass die Nahtlose Rohre aus Edelstahl ASTM A270 ist eine ausgezeichnete Wahl für Anwendungen in der chemischen Industrie, wo hohe Korrosionsbeständigkeit und Festigkeit erforderlich sind. Seine überlegenen chemischen und mechanischen Eigenschaften machen es für den Einsatz in rauen Umgebungen geeignet.

Quality and Mechanical Tests:
To assure the highest quality standards, the tubing is subjected to extensive testing and inspection programs that meet or exceed ASTM A270 A1016 A1016M test requirements. Testing includes reverse bend, reverse flattening, and flange tests. Eddy current testing is performed on 100% of the sanitary tube produced.
Heat Treatment (Annealing):
Inline hydrogen bright annealing to 1900°F (1040° C) minimum followed with a rapid quench.
Surface Finishes
SS tube surface finish is 20 µ-in Ra (0.5 µm) ID maximum, 30 µ-in Ra (0.8 µm) OD maximum surface roughness measured per ASME ANSI B46.1 with the profilometer reading at 90 degrees to the lay. Other finishes available upon request.
