Flange Pipe Specifications
Flange Pipe in Surabaya
Flange is one of the essential components in the piping system. Flange is also in the divide in various types, the different types of flange is one of them is based on the Facenya.
Here are the different types of Flange pPipa based on its category:
1. Type flange based on the rating
The Flange or that has another name forging (for the self reinforcement type), can be divided into several types when seen from the rating. Namely flange rating 150 #, 300 #, 600 #, 900 #, 1500 # even up to 2500 #. The flange division of the type of rating because the flange is working in a different pressure according to the rate, the flange rating is in the pound. Another chance, I will discuss it deeper about the rating on the flange.
2. Flange type based on size (NPS)
Flange can also be divided according to its flat size. So between a pipe with another pipe that is different in size, the Flangenya is different. To mention the size in the pipeline we know it with the term NPS. NPS is an abbreviation of the nominal pipe size, which is a nominal size used to distinguish the pipes.

Back regarding flange, division of Flange type is the NPSnya we will know the size of 1/2 ", 3/4", 1 ", 2"... 10 ", 12"... 24 "And so on, follow the size of the pipe that will be paired with the flange. I do not discuss it in detail the division of this type of flange because it is quite easy to understand.

The next question, if the flange in the distinguish is based on the NPSnya, is the flange differentiated also through the schedule as well as pipes? Apparently not, only a type of flange weldneck that has the schedulue.
3. Type flange based ANSI
In ANSI flange, we will distinguish the flange from its shape and its usefulness. Somewhat confusing actually give the type of flange classification from this side, because there are mention the division of this flange because of its design. One side again, the classification of flange here can be said in the distinguish from the Flangenya connection type, similar to the connection on the pipeline.
But I'm not going to make it happen because the essence is the same, but I will follow the literature I read, I share it based on ANSI.

What is ANSI? Ansi is the American National Standards Institute. Based on ANSI, flange differentiated type becomes:
1. Flange Type Weldneck
Weldneck flange, this type of flange has a very noticeable characteristic that is connection Flangenya using weld. This type of Flange is ordinary and most widely used in a plant, because it is easy to connect with pipes. This type of Flange can be used for high pressurework, either for low or high temperature.
2. Flange Slip-On and Lap Joint type
For the type of flange slip – on, it actually almost resembles with the type of flange lap joint. Both types of flange as the same as insert the main pipe into the flange, the difference when the slip on the pipe is not to get out of the flange, the type of lap joint, there is a side of the pipe coming out of the flange, and the side in Flangenya usually radial.

In slip on, the flange only enters one, the outer side and the inside will be weld. Because the pipe is entered into the flange, then in the slip on the slippage must be greater than the diameter outside SI pipe
In some literature, a slip opening is the one that calls it with the opening sleeve.
For the lap joint flange itself, this type of flange is usually used for pipes that are often disassembled, or in which the fluid is not allowed contact with weld welders or other types of connection. Because this pipe is not in the weld, the attachment can be twisting without thinking the position
Bolts. This type of flange can not be recommended for high pressure.

3. Threaded type Flange (threaded)
As the name suggests, this type of flange has the type of connection using the screw. Usually used for a system that is very prone to fire when using welding, besides this type of flange is cheaper.
4. Socket Type Flange
Flange socket, this type of flange is similar to slip on, only on the outer side of the flange there is a prisoner that causes the pipes to be inserted into it not translucent.
5. Reducing Flange
Reducing flange, this type of flange has a function to combines pipes that have different diameters.
6. Blind Flange
Blind flange is a type of flange that serves to close the flow, as does the stamp in the fittings. This type of flange is flat, no matter what it is because it does serve to shut down.
Then why is the flow closed? It could be a pipe that is closed in its intention to do maintenance later, or indeed the flow is closed for human access. For human access? Yes, as in the nozzle, there is usually a manhole that is closed with a blind flange.
Flange type based on installation method
There is still another division of flange based on how it is installed in the pipe or vessel. Indeed all such divisions are not the rules of the Bakunya, only the division of the flange of ANSI which may be closest to the actual classification of the flange.
But another division of the type of flange that I mentioned here is to introduce to you a variety of terms commonly used in the world piping. At the very least you have to familiarize yourself with the term, so that when you meet the term, you understand the intention.
