Specifications of JIS B2220 Stainless Steel Flanges

The JIS B2220 standard specifies the dimensions, tolerances, and technical requirements for stainless steel flanges used in piping systems. Typically made from high-grade stainless steel, these flanges are renowned for their corrosion resistance and durability, making them ideal for harsh environments. The flanges are available in various sizes, ranging from 10A to 600A, accommodating different pipe diameters and pressure requirements.

One significant aspect of JIS B2220 stainless steel flanges is their pressure ratings, which vary from 10K to 20K. This rating indicates the maximum pressure the flange can withstand without any risk of failure, ensuring safety and reliability in pressurized systems. Moreover, these flanges are designed to be compatible with various types of gaskets, further enhancing their adaptability in different applications.

Applications of JIS B2220 Stainless Steel Flanges

The versatility of JIS B2220 stainless steel flanges allows them to be used across multiple industries. One common application is in chemical processing, where resistance to corrosion and high temperatures is critical. These flanges securely fasten the piping, preventing leaks and maintaining the integrity of processes that involve aggressive chemicals.

Another prevalent use is in the food and pharmaceutical industries, where hygiene and sanitation are paramount. The non-reactive nature of stainless steel ensures that there’s no contamination of the materials being transported, making JIS B2220 flanges suitable for such sensitive applications.
