Stainless Steel 304L A778 Welded Pipe

Stainless steel 304L A778 welded pipe is commonly used in conveying systems under low pressure, normal temperature, or moderately corrosive environments. Understanding the positioning of the ASTM A778 standard and the properties of 304L material helps in achieving a better balance between cost and performance.

The ASTM A778 specification applies to untreated austenitic stainless steel welded pipe, primarily for structural applications, low-pressure conveying, decorative, or general industrial uses. Compared to ASTM A312, A778 has relatively different requirements for non-destructive testing and pressure testing, and is generally not the first choice for high-pressure pressure-bearing pipelines.
