Stainless steel pipes are widely used in automotive, food processing, marine engineering, and other fields. They offer advantages such as corrosion resistance, high strength, and excellent toughness. Stainless steel pipes can be categorized into austenitic stainless steel pipes, ferritic stainless steel pipes, martensitic stainless steel pipes, and duplex stainless steel pipes. Understanding these types helps us select the most suitable pipes for construction projects.

In pipeline systems for petrochemicals, water supply, food processing, and pharmaceuticals, we frequently encounter pipe schedule such as SCH40 and SCH40S.For those unfamiliar with them, SCH40 and SCH40S are very easy to confuse because they look nearly identical, differing only in the addition of an “S” after the “40.” SCH40S is considered superior to SCH40.Through this article, let’s explore the differences between SCH40 and SCH40S, providing you with a practical guide for selecting the appropriate pipe schedule.

We have compiled a stainless steel standard comparison chart to help you clearly compare standards across different countries, enabling you to make more informed decisions when selecting materials.
