In the world of piping systems, choosing the correct standard is crucial for ensuring the performance and longevity of pipes in various applications. ASME B36.10 and ASME B36.19 are two commonly referenced standards that outline the dimensions and specifications for different types of pipes. SSM will help you analyze and understand these key differences, enabling your engineers and project managers to make informed decisions to ensure the selected pipes meet the specific requirements of their applications. Here are the main differences:
What is ASME B36.10 ?
Scope: The ASME B36.10M standard specifies the dimensions, wall thickness, length, and other relevant requirements for seamless and welded carbon steel pipes. These pipes are commonly used in various industrial applications such as chemical processing, oil and gas transmission, and more.
Wall Thickness and Schedules: Pipes under this standard come with a wide range of wall thicknesses, indicated by Schedule numbers. This diversity allows for selection based on specific pressure and temperature requirements.
What is ASME B36.19 ?
Scope: The ASME B36.19 standard specifies the dimensions, wall thickness, length, and other relevant requirements for different types of stainless steel pipes, including austenitic and ferritic stainless steel. These pipes are commonly used in various industrial applications such as chemical processing, food processing, pharmaceuticals, and other environments with special requirements.
Wall Thickness and Schedules: Stainless steel pipes specified in this standard have thinner wall thicknesses, with Schedule numbers such as 5S, 10S, 40S, and 80S. These Schedules are specifically designed to meet the unique requirements of stainless steel applications.
Pipe Schedules
Despite using similar numeric designations for different thickness and size combinations, the Schedules in ASME B36.10M and ASME B36.19 standards differ in specific values and applicable ranges. Understanding these differences will help ensure that the pipes selected are suitable for their intended industrial applications.
The wall thicknesses for Schedule 10S for NPS 14 to 22 (inclusive) (DN 350–550, inclusive), Schedule 40S for NPS 12 (DN 300), and Schedule 80S for NPS 10 and 12 (DN 250 and 300) are different from the wall thicknesses specified in ASME B36.10M.You can see in the table below, it is marked in red and blue.
