Introduction of JIS B2220 Plate Flanges:
JIS B2220 Plate Flanges are manufactured from robust materials such as carbon steel or stainless steel, designed in a flat, circular shape with a smooth surface finish. They incorporate evenly distributed bolt holes around their circumference, enabling secure attachment to pipes or equipment. These flanges are primarily utilized in applications where operational pressures are low or negligible, spanning industries such as oil and gas, petrochemicals, water treatment, and HVAC systems.
Their versatility is underscored by compatibility with a wide array of piping configurations, enhancing their utility across diverse industrial settings. Known for their durability and resistance to corrosion, carbon steel and stainless steel variants are commonly chosen based on specific environmental demands and operational conditions.
JIS B2220 Plate Flanges are noted for their space-efficient design, which is particularly advantageous in installations where spatial constraints are a consideration. Installation and maintenance are streamlined due to their straightforward bolting mechanism, minimizing downtime during servicing activities.
Adherence to the JIS B2220 standard ensures dimensional accuracy, reliability in performance, and consistent quality across production batches. These attributes collectively position JIS B2220 Plate Flanges as reliable components for forming secure, leak-resistant connections within industrial piping and equipment systems.

Installation Principles of JIS B2220 Plate Flanges:
Surface Preparation: Begin by preparing the mating surfaces of the pipes or equipment that will be joined using the flanges. Ensure these surfaces are clean, smooth, and free from any debris or imperfections that could compromise the sealing integrity.
Alignment: Position the flat plate flanges against the mating surfaces of the pipes or equipment. Ensure that the bolt holes on the flanges align perfectly with those on the mating components. Proper alignment is critical to facilitate easy insertion of bolts and to prevent misalignment during tightening.
Bolt Insertion: Insert bolts through the aligned bolt holes of the flat plate flange and the mating component. Use appropriate bolts of suitable length and strength grade as specified by industry standards or project requirements.
Bolt Tightening: Gradually tighten the bolts in a diagonal pattern using a torque wrench or other suitable tools. This method helps distribute the load evenly across the flange connection and ensures uniform compression of the gasket (if used). Follow the recommended torque specifications to achieve the required tightness without over-tightening, which could damage the flanges or the gasket.
Gasket Installation (if applicable): If a gasket is required for sealing, place it between the mating surfaces of the flanges before inserting bolts. Ensure the gasket material is compatible with the operating conditions (temperature, pressure, media) and verify its correct positioning to prevent leaks.
Verification: After tightening all bolts to the specified torque, inspect the entire flange assembly for any signs of misalignment or gaps between the flanges and mating surfaces. Conduct a visual check and, if necessary, perform a pressure test to verify the integrity of the connection and ensure there are no leaks under operating conditions.
Final Checks: Once installation is complete and verified, protect the flange assembly from external damage and environmental factors. Monitor the connection periodically to ensure continued tightness and performance over time.
