Product Description of ASTM A312 Seamless Stainless Steel Pipe

1. Physical Specifications

Specification	Details
Diameter	Available in a wide range of diameters, typically from 1/8 inch (3.175 mm) up to 24 inches (609.6 mm), to meet diverse industrial requirements. Custom diameters can also be manufactured upon request.
Wall Thickness	Wall thickness varies according to different schedules (e.g., Sch 5S, Sch 10S, Sch 40S, Sch 80S). Thickness can range from as thin as 0.065 inches (1.651 mm) for light - duty applications to 0.500 inches (12.7 mm) or more for high - pressure situations.
Length	Standard lengths are usually 20 feet (6.096 meters) or 40 feet (12.192 meters). However, cut - to - length pipes can be provided, with the ability to produce lengths from a few inches to the standard lengths, enabling precise fitting for specific projects.
Surface Finish	The pipe has a smooth internal and external surface finish. Common surface finishes include bright annealed (BA) for a clean and shiny appearance, which also enhances corrosion resistance, and mill finish for general - purpose applications.

2. Material Properties

• Stainless Steel Grades: It is available in popular austenitic stainless steel grades such as 304, 304L, 316, and 316L. These grades offer excellent corrosion resistance, especially in harsh environments containing acids, alkalis, and salts. For example, Grade 316L is highly resistant to pitting and crevice corrosion in chloride - rich environments, making it suitable for marine and chemical processing applications.
• High - Temperature Resistance: The pipe can withstand high temperatures without significant loss of mechanical properties. Austenitic stainless steels in ASTM A312 have good thermal stability, allowing them to be used in applications such as heat exchangers, boilers, and high - temperature fluid transportation systems.
• Mechanical Strength: It has high tensile and yield strength, providing reliable performance under pressure. The seamless construction further enhances the pipe's ability to withstand internal and external forces, ensuring long - term durability.

3. Applications

• Chemical Industry: Used for transporting various corrosive chemicals, acids, and solvents due to its excellent corrosion resistance.
• Food and Beverage Industry: Ideal for applications where hygiene and corrosion resistance are crucial, such as in food processing lines, dairy equipment, and beverage production.
• Oil and Gas Industry: Suitable for use in offshore platforms, refineries, and pipelines, where it can handle the harsh conditions of oil and gas extraction, refining, and transportation.
• Power Generation: Employed in power plants for steam and water piping systems, as well as in heat exchangers and condensers.
