JIS Flange

JIS Flange offers a variety of corrosion-resistant flanges to meet your needs. Our flanges are available in a variety of sizes and styles and are easy to install and use. They are strong and durable, making them ideal for a variety of applications.

JIS Flange is a type of pipe flange that has been used for several years. It’s extremely durable and is designed to make it easy to install plumbing systems.

This product can be used in many different situations, including residential and commercial construction as well as industrial applications.

1. JIS Flange Definition and What Does It Do

JIS stands for Japanese Industrial Standards, which means that these JIS flanges meet JIS standard flange specifications. JIS is the Japanese version of ISO. A JIS flange is a type of pipe flange that has been used for several years. It’s extremely durable and is designed to make it easy to install plumbing systems.

JIS flange sizes and JIS flange weight are not compatible with North American or British Standard Pipe Threads as some inch-sized dimensions differ from those of JIS screws. JIS flanges are used in applications such as paper machines, pulp, and wastewater treatment plants.

2. JIS Flange Key Features

There are several key features that make JIS Flange a top choice for contractors:

Circular Face

JIS flanges have a circular face which is supposed to be flat on the inside. But it’s not always so perfect.

So this causes some problems, like gas leakage and oil leakage on pumps and valves on ships after some time due to carbonization or oxidation of insulating materials of equipment that rotates; but it doesn’t cause any problem on pipe connections – which is more important for pipelines.

That’s because pipe superior connection works under lower pressure assemblies (so there’s no need for high machine efficiency) and also has the weight of a substance (it can work without rotating).

It really poses a lot of burden on hydraulics; therefore, flange standard JIS cannot be used on most hydraulic machines. Most hydraulic machines have been replaced by electric pumps and valves due to various reasons.

No Center Bolt Hole

JIS flange has no center bolt hole. And this is for a reason: there’s a lock ring that holds the blind flange onto the piping with bolts from both sides just like a usual bolted joint using 2 bolts.

If they put a center bolt hole then it would weaken the fillet weld neck flange connection area that joins the two sheets together. That’s why they have no center bolt hole. And if they have it – as in North American Flange (in some cases) – then you can remove it as long as no one else needs such as if you need to replace it with JIS flange.

Key Grooves

In the JIS flange, there are 6 key grooves on both sides of the joint face to be able to form a good seal. And only JIS flanges have them. These grooves are formed by rollers that press down the inner face while welding which makes these 6 key grooves.

Without them, it’s very difficult to make a long-lasting seal between 2 sheets. Even if you did manage to weld them together somehow without these grooves, air will leak out easily because these two can be separated rather simply. So this is why North American Flange doesn’t have any groove at all (at least not many kinds).

Standardization

Standardization is relatively simple with only these 4 standards: D, G, E, and F standards so pretty much anyone can make them easier than North American Flange.

North American Flange has more standards like ANSI/ASME B16.5 in the U.S., En1092 in Europe, etc… This is because they have different classes for resistance in these countries or areas. They’re not exactly different standards but more like classifications.

3. Benefits of Using JIS Flange

There are many benefits of using JIS Flange. Some of these benefits include:

Very Strong and Can Withstand a Lot of Pressure

The fact is the JIS Flange is very strong and can withstand a lot of pressure. This means it can be used for industrial uses in Japan. Thus, if you are in a country that uses a similar industrial process to Japan’s, then perhaps using the JIS Flange would be best for you.

The Pressure Rating Is Listed on the JIS Flanges

Another good thing about these flanges it has a JIS flange pressure rating listed on them! In addition, when someone says they want a certain JIS flange rating, they usually mean from this company because there aren’t any other companies that make one with such high ratings.

So if you want something reliable that will last long under much stress then go with the JIS Flange.

There is a Size for Everything

This company has every size of the flange, so there is no need to worry about not being able to find what you are looking for.

They have hundreds of different sizes to choose from. However, if you are looking for something very specific and the right size is not listed on the site, then do let them know about it and they can make it happen. The JIS Flange will meet your need!

It’s Affordable

This brand of flanges goes for a relatively cheap price. This makes it affordable for anyone to buy; well at least most people should be able to afford them! The price is reasonable compared to other companies that sell flanges even though this company’s products are made well like all others (JIS standard).

So if you want an item that will last long under much pressure but don’t want to pay too much money, go with the JIS Flange.

4. The Difference Between a JIS Flange and Other Types of Flange

Flange JIS are made to conform to the Japanese Industrial Standard, which is an international standard that specifies the flange JIS standard dimensions and tolerances of mechanical components.

Some of the key differences between JIS standard flanges and other types of flanges include:

• JIS flanges have a smaller pipe bore diameter than other types of lap joint flange
• JIS flanges have a thicker flange than other types of socket weld flange
• JIS flanges have a different bolt pattern than other types of threaded flange
• JIS flanges are used in different industries than other types of flat face flange
• JIS flanges have a larger height than other types of ASME flanges
• JIS flanges are not interchangeable with most other types of standard flanges. The only exception to this rule is if the JIS design can be ground down to make it compatible with ANSI or DIN standards. Most machinists recommend using an adapter sleeve for this task, instead of trying to grind down the JIS design.

5. When You Should Use a JIS Flange

There are a few key situations when you should use a JIS flange:

• When you are working in a Japanese-based manufacturing plant
• When you are working with components that need to conform to the Japanese Industrial Standard
• When you are working with components that have a smaller bore diameter than other flanges
• When you need a thicker flange than other flanges
• When you need a different bolt pattern than other flanges
• When you need a larger height than other flanges
• When you need to use the component in question with several different types of standards
• When it is not possible or practical try to alter your JIS design to make it fit with another type of flange standard

It’s also worth noting that it is usually best practice to consider the three most important measurements for any piece of mechanical equipment: torque, speed, and accuracy.

If you are working on a project where one of these values must be maximized over the others, then you should choose a JIS design if all other factors are equal.

6. JIS Flange Average Price

JIS b2220 flanges are used in a wide range of manufacturing companies, both domestically and internationally. As such, the price for these products varies greatly depending on the buyer’s needs. You can expect to pay between $50 and $300 for a JIS flange, although most standard prices fall closer to the middle of that range.

However, there is no one-size-fits-all answer to the question of price. JIS flanges are made to specific JIS flange dimensions and tolerances, so the price will vary depending on the size and type of flange that you need.

That being said, most machinists agree that a JIS flange will typically be more expensive than other types of standard flanges. This is because JIS flanges are more specific to the components they are being used for. This means that it may take longer to fabricate a JIS flange, compared with other standard options.

For these reasons, it is usually best practice to look for a company that is experienced with both machines and materials when it comes time for price negotiations.

Online retailers typically have a wide selection of JIS flanges, and they often offer discounts on these products. This is because they have lower overhead costs than traditional brick-and-mortar stores. Be sure to compare the prices between online retailers to find the best deal.

Local Machinists

If you need a JIS flange that is not readily available online, your best bet is to go to a local machinist. Machinists typically have a wide variety of flanges in stock, and they can fabricate any size or type of flange that you need. This can be a great option if you need to order a JIS flange in bulk.

Second-Hand Machinists

If you know someone who is currently using a JIS flange, then they may have the equipment necessary to manufacture this product for you at a lower price than other machinists.

These companies often have used equipment that can be sold at a discount if it is not being used as regularly as before. This can represent significant savings for your company, especially when combined with any discounts or promotions available from your local store or online retailers.

Direct Manufacturers

Direct manufacturers are companies that make their own products. This means that they do not sell directly to the end-user, but rather to distributors or other stores. Since these companies do not need to operate storefronts or provide customer support, they can provide lower prices than traditional retailers.
