About ASTM A270 JIS G3447
Stainless Steel Welded Tube ASTM A270 and JIS G3447 are two different standards that specify the requirements for stainless steel welded tubes used in different industries.
- ASTM A270: ASTM A270 is a standard specification for seamless and welded austenitic stainless steel sanitary tubing intended for use in the dairy and food industry, as well as in pharmaceutical and biotechnology applications. It covers tubes of various sizes and wall thicknesses.
The ASTM A270 standard specifies the following requirements:
- Chemical composition of the stainless steel material
- Mechanical properties such as tensile strength, yield strength, and elongation
- Dimensions and tolerances for the tube’s outside diameter, wall thickness, and length
- Surface finish requirements, including roughness and cleaning
- Nondestructive electric tests, such as eddy current or hydrostatic tests
- Heat treatment requirements, if applicable
- Packaging and marking guidelines
- JIS G3447: JIS G3447 is a Japanese industrial standard that specifies the stainless steel sanitary pipes used in the food, beverage, and pharmaceutical industries. It covers both seamless and welded tubes.
The JIS G3447 standard specifies the following requirements:
- Chemical composition of the stainless steel material
- Mechanical properties such as tensile strength, yield strength, and elongation
- Dimensions and tolerances for the tube’s outside diameter, wall thickness, and length
- Surface finish requirements, including roughness and cleaning
- Nondestructive tests, such as eddy current or hydrostatic tests
- Heat treatment requirements, if applicable
- Packaging and marking guidelines
It’s important to note that while both standards cover stainless steel welded tubes used in sanitary applications, they are specific to different regions and industries. ASTM A270 is commonly used in the United States and is widely accepted internationally, while JIS G3447 is a Japanese standard primarily used in Japan and may have some variations in requirements compared to ASTM A270.
