In industrial piping systems, selecting the correct flange dimensions is essential to ensure accurate alignment, leak prevention, and safe operation. However, different regions and industries use different standards – the most common being JIS (Japan), ANSI (USA), and DIN (Europe).

In this article, Sunjin Metals Vina (SJM Vina) will guide you through the differences between flange standards and how to read standard dimension charts correctly.

Steel flanges are essential components in industrial piping systems. To select the correct flange for each application, users must understand the markings engraved or stamped on the flange surface. These markings indicate technical specifications such as standard, material, size, pressure rating, and other critical data.

Sunjin Metals Vina (SJM Vina) will guide you through the most common flange markings and how to read them properly for safe and effective usage.

Steel flanges play a critical role in industrial piping systems, ensuring secure connections, leak prevention, and ease of maintenance. However, to guarantee performance and compatibility, selecting the right flange standard is essential.

Globally, the most widely adopted flange standards include ANSI (USA), JIS (Japan), DIN (Germany), and BS (UK). Each standard reflects regional industrial practices and varies in size, pressure ratings, and design.

In this article, Sunjin Metals Vina (SJM Vina) will help you clearly understand these standards and provide guidance on how to choose the appropriate one for your project or market.
