JIS B2220 Flanges Explained: Types, Sizes, and Pressure Ratings
JIS B2220 Flanges Explained: Types, Sizes, and PressureRatings
It is for connecting pipes, valves, pumps, and other equipment within piping systems and among the various international standards that JIS B2220 Flanges belongs. It is recognised within the Japanese and global industrial sectors.
Typically, JIS (Japanese Industrial Standards) B2220 provides specifications for steel pipe flanges used in pressure piping systems. It is used mainly in industries that demand high performance, reliability, and standardization.
Hence, in this blog we at Bagoda Steel Project, a leading JIS B2220 Flanges manufacturer in India offer you all information that you need to know about JIS B2220 Flanges its types, sizes, pressure ratings and where you can buy JIS B2220 Flanges of high ‘Premium’ quality that meets international quality standards at an affordable JIS B2220 Flanges Price for domestic and international markets.
What are JIS B2220 Flanges?
JIS B2220 Flanges are standardized steel flanges manufactured as per Japanese Industrial Standards for use in piping systems. They are shaped for fluid transmission in oil and gas, petrochemical, water treatment, marine, and competence generation industries. The JIS B2220 specification includes various flange types that can withstand different pressure ratings and temperature requirements, constructing them ideal for demanding environments.
At Bagoda Steel Project, we offer a wide range of high-quality JIS B2220 flanges meet international quality standards and are suited for both domestic and global markets.
Types of JIS B2220 Flanges
There are several types of JIS B2220 flanges, separate mapped out for identified piping limitations and connection tactics. Here are the influential types:
- Slip-On Flange (S/O Flange)
Slip-on flanges are uncomplicated to install and weld onto the pipe. They are slipped over the pipe and then welded both inside and outside to provide wealth and embargo leakage. These flanges are commonly used in low-pressure and non-critical applications.
- Weld Neck Flange (W/N Flange)
Weld neck flanges are known for their high wealth and resistance to dishing. They feature a long tapered hub and are welded to the pipe. They are ideal for high-pressure and high- temperature applications, predominantly in the oil and gas and chemical industries.
- Blind Flange (B Flange)
Blind flanges are used to close the termination of piping systems or pressure vessel openings. They authorize the path for straightforward access for inspection and maintenance. Blind flanges must withstand high pressure and are commonly used in testing and temporary sealing.
- Socket Weld Flange (S/W Flange)
Socket weld flanges are similar to slip-on flanges, still they have a socket where the pipe is inserted before being welded. This type provides a smooth bore and is productive for small- diameter, high-pressure piping.
- Lap Joint Flange
Used with a stub termination, lap joint flanges are gracefully compiled and disassembled. They are ideal for systems that require frequent inspection and maintenance, uniquely in corrosive environments where the flange can become produced from a less steep material.
- Threaded Flange (T Flange)
Threaded flanges are used in low-pressure piping systems and create space effortless session without welding. These are commonly used in small-diameter piping with internal threads.
Pressure Ratings of JIS B2220 Flanges
JIS B2220 flanges are reachable in various pressure ratings, designated by "K" class (e.g., 5K, 10K, 16K, 20K, and 30K). These ratings represent the maximum pressure (in kgf/cm²) the flange can withstand.
Normal Pressure Classes
- 5K: Precise for low-pressure systems such as water lines and ventilation.
- 10K: Most commonly used class, ideal for water supply, drainage, and industrial systems.
- 16K:Used in moderate pressure applications such as oil refineries and workflow plants.
- 20K & 30K: Built for high-pressure and high-temperature rules, including petrochemical and thermal asset plants.
Note: Higher pressure classes require stronger tools and preferred welding to confirm leak-proof performance.
Sizes of JIS B2220 Flanges
JIS B2220 flanges are manufactured in a wide range of sizes, typically ranging from 15A to 1500A (½" to 60"). These sizes refer to the nominal bore (NB) or nominal pipe size (NPS). We at Bagoda Steel Project have given it in a table below:
| Nominal Size (A) | DN (mm) | Inch Equivalent |
|---|---|---|
| 15A | DN15 | ½″ |
| 20A | DN20 | ¾″ |
| 25A | DN25 | 1″ |
| ... | ... | ... |
| 1500A | DN1500 | 60″ |
Flanges furthermore vary in scale such as bolt hole size, pitch circle diameter (PCD), thickness, and outer diameter, which are specified truthfully in the JIS B2220 standard to promise compatibility.
Applications of JIS B2220 Flanges
JIS B2220 flanges are absolutely used across industries that rely on reliable and gather piping systems. Some of the key applications merge:
- Petrochemical and Refineries: Used for high-pressure fluid handling systems.
- Water Treatment Plants: Employed in both low and high-pressure pipelines.
- Power Plants:Influential for thermal and nuclear applications where high-temperature resistance is needed.
- Marine & Shipbuilding: Utilized in seawater and counterweight water systems.
- Food & Beverage Industry: Stainless steel JIS flanges are ideal for sanitary and hygienic piping.
