Product Description

JIS B2220 Plate Flange DN10–DN600, 5K–40K for High-Pressure Piping Systems

JIS B2220Slip-On Plate Flange is a flat plate–type flange designed to slide over the pipe and be welded on both the inside and outside. It combines the cost efficiency of plate flanges with the ease of alignment of slip-on connections, making it a popular choice for waterworks, fire protection, HVAC, and general industrial piping systems.

Manufactured from carbon steel or stainless steel plate, Slip-On Plate Flanges are widely used in low to medium pressure applications where installation convenience, dimensional flexibility, and economic efficiency are required.

Installation Process

To ensure safe and leak-free operation, follow these installation steps:

Verify Specifications
Confirm flange size, pressure class, material, and bolt pattern match the mating flange.
Inspect Sealing Surfaces
Ensure flange faces are clean, smooth, and free from damage.
Install Suitable Gasket
Select gasket material based on pressure, temperature, and media (rubber, PTFE, spiral wound, etc.).
Align Bolt Holes
Position the blind flange accurately against the mating flange.
Tighten Bolts Evenly
Use a cross-tightening sequence and apply uniform torque.
Pressure Test
Conduct hydrostatic or pneumatic testing to confirm sealing integrity.
Tip: Always follow recommended torque values and gasket manufacturer guidelines.

PRODUCT INFORMATION

Flange,also called flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. 

Because the flange has good comprehensive performance, it is widely used in chemical industry, construction, water supply,drainage, petroleum, light and heavy industry, refrigeration, health, water heating, fire, power, aerospace, shipbuilding and other basic projects.

FAQ

Q1: What is the purpose of a JIS B2220 blind flange?
A blind flange is used to seal the end of a pipeline or equipment connection, preventing fluid flow while allowing future access.

 
Q2: Can JIS B2220 blind flanges be used permanently?
Yes. They can be used for both temporary isolation and permanent pipeline closure, depending on design requirements.

 
Q3: What is the difference between JIS blind flanges and ASME blind flanges?
They differ in dimensions, bolt circle, thickness, and pressure rating systems. JIS flanges are not directly interchangeable with ASME flanges.

 
Q4: How do I choose the correct pressure class (5K, 10K, 20K)?
Select the pressure class based on system design pressure, operating temperature, and safety factors.

 
Q5: Are custom sizes or coatings available?
Yes. Custom dimensions, materials, coatings, and markings can be supplied upon request.
