Description
JIS G3448 and G3468 are Japanese Industrial Standards that specify the requirements for stainless steel welded pipes. These standards provide guidelines for the production and testing of stainless steel pipes used in various industries.
JIS G3448 specifically covers stainless steel sanitary pipes, which are commonly used in food processing, pharmaceutical, and chemical industries where cleanliness and hygiene are crucial. The standard specifies the dimensions, tolerances, and mechanical properties of these pipes.
On the other hand, JIS G3468 focuses on large-diameter welded stainless steel pipes for general applications. These pipes are used in various industries, including construction, infrastructure, and oil and gas. The standard outlines the requirements for dimensions, tolerances, mechanical properties, and testing methods for these pipes.
Both standards ensure the quality and reliability of stainless steel welded pipes by setting specific criteria for material composition, manufacturing processes, and inspection procedures. They help facilitate international trade by providing a standardized framework for the production and evaluation of these pipes.
It’s important to note that if you have any specific questions or requirements related to JIS G3448 or G3468 stainless steel welded pipes, I would be happy to provide further assistance.
JIS G3448 is mainly for small-diameter stainless steel fluid delivery pipes, suitable for medium and low-pressure fluid systems.
JIS G3468 is mainly for large-diameter stainless steel pipes, suitable for structural pipes and low-pressure fluid delivery.
