Pipe Standard Size

It should be selected in combination with specific scenarios and specifications.

• International standards: ANSI B36.10M, API and other specifications define the nominal diameter (DN) and wall thickness grade (such as SCH 40, SCH 80) of carbon steel and stainless steel pipes
• Material differences: Different material size standards may also be different, such as PVC and galvanized steel.
• Application areas: Different fields use different unit standards. For example, water pipes often use imperial units, but oil and gas pipelines mostly use metric or API standards.
