Manufacturer Suppliers of SCH 40S Super Duplex Tubing, SDSS Instrument Tubing and SAF 2507 Tube as per ASME B36.19 and ASTM A790 A789, View our sizes and dimension chart
ASME B36.19M is the standard specification for stainless steel pipe sizes and dimensions. Super Duplex Saf 2507 pipe is a grade of Super Duplex stainless steel characterized by its enhanced high strength and excellent corrosion resistance compared to traditional stainless steel grades, particularly in aggressive environments such as those containing chlorides. Seamless pipes made from S32750 stainless steel are commonly used in industries such as oil and gas, chemical processing, and marine engineering.
Technical Specifications & Cross-References
Industrial sourcing requires absolute alignment between dimensional standards and material delivery specifications:
- Dimensional Standard: ASME B36.19M (Stainless Steel Pipe) / ANSI B36.19
- Material Standards: ASTM A790 / ASME SA790 (Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe)
- Tubing Specifications: ASTM A789 / ASME SA789 (Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service)
- Forging & Fitting Grades: ASTM A182 F53 (Flanges/Forgings), ASTM A815 WP-S (Pipe Fittings)
Here's a general overview of the available sizes for seamless pipes covered under ASME B36.19M for super duplex S32750 stainless steel:
- NPS 1/8 (DN 6) to NPS 12 (DN 300): These sizes cover a wide range of industrial and commercial applications.
- Outside Diameters: The actual outside diameters for each nominal pipe size are specified within the standard and are typically based on standard pipe schedules (e.g., Schedule 5S, 10S, 40S, 80S).
- Wall Thickness: The wall thickness of seamless pipes can vary depending on the specific requirements of the application and is typically specified in inches or millimeters.
