What Is meant by JIS flange?

JIS flanges refer to a specific type of flange standard developed by the Japanese Industrial Standards (JIS) organization. Flanges are important components used in piping systems to connect pipes, valves, and other equipment. They provide a means for easy assembly, disassembly, and maintenance of these systems.

The JIS flange standard specifies the dimensions, materials, and technical requirements for flanges used in various industries in Japan. These standards ensure the compatibility and interchangeability of flanges across different manufacturers and applications. The JIS flange standard is widely used in industries such as oil and gas, chemical, petrochemical, power generation, and shipbuilding.

JIS flanges come in different types, such as slip-on flanges, blind flanges, welding neck flanges, socket weld flanges, threaded flanges, and lap joint flanges. Each type has specific features and applications. Slip-on flanges, for example, are easy to align and attach to the pipe, making them suitable for low-pressure systems. Welding neck flanges, on the other hand, provide a strong connection and are commonly used in high-pressure and high-temperature applications.

The dimensions of JIS flanges are specified in terms of nominal pipe size (NPS) and pressure class. The NPS represents the nominal diameter of the pipe, while the pressure class indicates the maximum pressure the flange can withstand. JIS flanges are available in various sizes ranging from 10A (10 mm) to 1500A (1500 mm) and pressure classes from 5K to 63K. The pressure class determines the thickness and strength of the flange.

Materials used for JIS flanges depend on the application and the fluid or gas being transported. Common materials include carbon steel, stainless steel, alloy steel, and cast iron. The selection of material is crucial to ensure the flange's compatibility with the fluid's corrosiveness, temperature, and pressure conditions.

JIS flanges undergo rigorous testing and inspection to ensure their quality and performance. These tests include dimensional checks, material composition analysis, mechanical properties evaluation, and pressure testing. Flanges that meet the JIS standards receive certification and marking to indicate their compliance.

Proper installation and maintenance of JIS flanges are essential to ensure the integrity and safety of the piping systems. During installation, the flange faces should be clean, flat, and free from any debris or contaminants. Bolts should be evenly tightened in a specific sequence to achieve a uniform and secure connection. Regular inspection and maintenance of flanges are necessary to detect any signs of leakage, corrosion, or damage.

In conclusion, JIS flanges are a standardized type of flange developed by the Japanese Industrial Standards organization. They provide a reliable and compatible means of connecting pipes and equipment in various industries. With their specific dimensions, materials, and technical requirements, JIS flanges to ensure the integrity and performance of piping systems. Proper installation, maintenance, and adherence to the JIS standards are crucial for the safe and efficient operation of these flanges

Types of Flanges We Manufacture:

Hub Flanges: 

The elevated circular regions where the spokes are joined to a bicycle hub are called hub flanges. By uniformly spreading the spoke strain along the hub's diameter, they are often made of steel or aluminium and offer the structural support for the wheel.

Without Hub Flanges: 

some variations of bicycle wheel designs that do not have traditional hub flanges.

For example, some single-speed and fixed-gear bicycles use what is called a "flip-flop" hub, which has a threaded section on both sides of the hub for mounting a freewheel or fixed gear cog. These types of hubs may have a flat surface where the spokes are attached instead of traditional raised flanges.

Plate Flanges:

In industrial applications, plate flanges are a type of flange that are frequently used to connect pipes, valves, and other machinery. Usually formed of materials like carbon steel, stainless steel, or cast iron, they are comprised of a flat, circular disc with uniformly spaced bolt holes all the way around.

Slip on Flanges:

In industrial applications, slip-on flanges, a form of plate flange, are frequently used to connect pipes, valves, and other machinery. They typically consist of a flat, circular disc with a bore hole in the centre and uniformly spaced bolt holes around the periphery and are composed of materials like carbon steel, stainless steel, or cast iron.

Blind Flanges:

An end of a pipe, valve, or pressure vessel is sealed with a blind flange, a type of flange. In order to provide a tight seal that prevents fluid or gas from escaping, they are made to be bolted onto the end of the pipe or piece of machinery.

Socket Weld Flanges:

Socket weld is a type of pipe fitting that is used to join two pipes together by inserting the end of one pipe into the socket of another. The joint is then welded, creating a strong and permanent connection between the two pipes.
