What Is Jis Flange?

A set of specifications for flanges used in Japan are known as JIS (Japanese Industrial specifications) flanges. These specifications are comparable to international flange standards like ANSI (American National Standards Institute) and DIN (Deutsches Institut für Normung, German Institute for Standardisation). JIS flanges are used in a variety of industries, including oil and gas, petrochemicals, and shipbuilding.

Carbon steel, stainless steel, or aluminium are frequently used to make JIS flange. To accommodate various applications, they are available in various diameters and pressure ratings. The two types of JIS flanges are known as Jis 5k Flanges and Jis 10k Flanges, respectively. Blind flanges are used to seal off the ends of pipes or vessels, whereas flanges are used to connect pipes or fittings.

JIS flanges are created to adhere to particular standards for testing, materials, and size. These standards guarantee interchangeability between Flanges Manufacturer in India and other flanges that adhere to the same specifications. In addition to being widely utilised in Japan, JIS flanges are also prevalent in other nations, particularly in Asia.

Different Types of Jis Flanges:

JIS 5K FLANGE:

The Japanese Industrial Standards (JIS) regulation dictates that the JIS 5K flange has a pressure rating of 5 kilogrammes per square centimetre (kg/cm2). In Japan and several other nations that employ JIS standards, it is widely used in plumbing systems.

JIS 10K FLANGE:

Another type of flange that meets Japanese Industrial Standards (JIS) requirements is the JIS 10K flange, which has a higher pressure rating of 10 kilogrammes per square centimetre (kg/cm2). The piping systems in Japan and other nations that adhere to JIS norms frequently employ it.

The JIS 10K flange, like all JIS flanges, is intended to link pipes or pieces of equipment securely and tightly. It comprises of a plate that is round and has uniformly spaced bolt holes all the way around it. The flange face can be either flat (FF) or raised (RF).

JIS B2220 FLANGE:

Steel pipe flanges are covered under the Japanese Industrial Standards (JIS) specification JIS B2220. Dimensions, materials, and technical specifications for several types of flanges used in piping systems are laid out in JIS B2220.

Different pressure ratings, such as 5K, 10K, 16K, 20K, 30K, and 40K, are assigned to JIS B2220 flanges. A higher number denotes a higher pressure rating, which describes the flange’s capacity to withstand pressure.

Uses Of Jis Flange:

JIS (Japanese Industrial Standards) flanges are used in a variety of industries for connecting pipes or vessels. Here are some common uses of JIS flanges:

Oil and Gas Industry:

JIS flanges are widely used in the oil and gas industry for connecting pipes, pumps, valves, and other equipment. They are commonly used in offshore platforms,

refineries, and petrochemical plants.

Shipbuilding Industry:

JIS flanges are used in the shipbuilding industry for connecting pipes and valves on ships and vessels. They are also used in the construction of offshore structures such as drilling rigs and production platforms.

Chemical Industry:

JIS flanges are used in the chemical industry for connecting pipelines and equipment such as reactors, distillation columns, and heat exchangers.

Water Treatment Industry:

JIS flanges are used in the water treatment industry for connecting pipes and fittings in water treatment plants, desalination plants, and wastewater treatment plants.

Construction Industry:

JIS flanges are also used in the construction industry for connecting pipes and fittings in HVAC systems, plumbing, and fire protection systems.

Overall, JIS flanges are widely used in many industries for their reliable performance and interchangeability with other flanges that meet the same standards.
