Stainless Steel Plate Flanges JIS B2220 30K Plate Flanges for Welding Blank Flange Plate Raised Face/Flat Face for Chemical Industry Pipelines

Introduction of JIS B2220 Plate Flanges:

The JIS B2220 plate flange is crafted from a solid piece of plate material, typically steel or stainless steel. It takes the form of a flat, circular disc featuring evenly spaced bolt holes encircling its perimeter. This design allows the plate flange to securely connect two segments of pipe or equipment by bolting them together, forming a tight and leak-resistant joint.

JIS B2220 Plate flanges find widespread use in applications characterized by low or no pressure at ambient temperatures. They are prominently employed across industries such as oil and gas, petrochemicals, water treatment, and HVAC systems. These flanges offer several advantages, including space efficiency due to their thinner profile compared to other flange types.

The choice of material for JIS B2220 plate flanges varies based on specific application requirements. Carbon steel and stainless steel are commonly favored due to their robustness, durability, and resistance to corrosion. Selection of material hinges on factors such as the nature of the transported fluid, operating temperature, pressure conditions, and environmental considerations.

These plate flanges are versatile, compatible with various piping systems, and relatively straightforward to install while ensuring a dependable connection. However, it is crucial to meticulously match the flange's size, pressure rating, and material specifications to the unique demands of each application.

Material Grades of Stainless Steel Plate Flanges:

1.ASTM A182 F304/304L: This is a common material grade for stainless steel flanges, suitable for general industrial applications. It primarily consists of 18% chromium and 8% nickel, providing good corrosion resistance and oxidation resistance. F304L is the low carbon version, suitable for use in welding conditions.

2.ASTM A182 F316/316L: This is a material grade with better corrosion resistance, commonly used in corrosive environments such as chemical, petroleum, and marine industries. It contains 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, which enables resistance against strong corrosive media like sulfuric acid and hydrochloric acid. F316L is the low carbon version, helping to reduce intergranular corrosion during welding.

3.ASTM A182 F321: This is a titanium-stabilized material grade for stainless steel flanges, suitable for high-temperature environments. It contains 18-20% chromium, 9-12% nickel, and also includes 0.15-0.30% titanium, enhancing corrosion resistance and high-temperature performance.

In addition to the above-mentioned common material grades of stainless steel flanges, there are other material grades such as ASTM A182 F347, ASTM A182 F904L, etc., which have different chemical compositions and characteristics, suitable for different working conditions and media.

When selecting the material grade of stainless steel flanges, it is necessary to evaluate specific factors such as the working environment, corrosive nature of the media, temperature, and pressure requirements to ensure the appropriate material grade is chosen to meet the engineering needs.
