Types of  flange pipe fittings and pipe fittings: (Fitting) connections There are different types of connections, each in the plumbing system, related to the specific work described below. The most important connections are the following:

What are the different types of flange pipe fittings?

What are the different types of flange pipe fittings? In order to branch off the flow line, a three-way is used, which may be smaller or equal to the other two heads, depending on the need for the diameter of the series, which is the branch.

For connections in different industries, there are different types of flanges, which we will introduce and apply. To choose and buy the best type of flanges, you can get advice from Kara Parnian Shargh Company.

Flange FaceThese flanges, as the name implies, have a smooth, non-grooved surface. They are used in low pressure and low temperature connections. They are made of iron, cast iron, steel and in some cases polyethylene berry alloys for the production of polyethylene pipes. They are the cheapest type of flange on the market.

Blind Flange

Blind flanges are usually without holes and are used to block the end of the casing of high-pressure sources or valves. Often used in large sizes, these flanges are suitable for use at high pressures and are the most stressful flanges of all types of flanges.

Reducer

For places where the diameter needs to be changed, this connection is used, which exists in two types, co-centered and heterogeneous.

pipe flange types are steel parts that are used for connection items such as shock absorbers, valves, etc.

There are various ways to connect a pipe and its items to each other or to equipment, such as welding, etc. One of these is flange connections.

Manufacturing process of flange pipe fittings

Manufacturing process of flange pipe fittings What is a flange?The most important reason to use this method is Removable, which means that if you weld two pipes directly to each other, if you want to separate them, you have to cut and re-weld, but in If you use flanges, you can do this by opening and closing the bolts. 

In this method, a flange is welded to both pipes and these two flanges are placed facing each other from the Flange Face section and are pressed and tightened together by bolts & nuts. 

Application of flanges in industry and facilities Connecting pipes to equipment such as pressure vessels, pumps, compressors, etc . 

Change the material in the pipe.Valves and other items in the pipeline and may need to be repaired .

Connect to Instrument devices that require possible repairs or calibration.

All other items that need to be separated. of connection is much higher than welding, but it is widely used due to the mentioned advantages.

Classification of 4 inch pipe flange and standard dimensions of steel flanges

An international reference should be used to identify flanges and know their dimensions and sizes, because in order for flanges to be placed opposite each other and to be bolted, we need to know the size of the holes and their dimensions:

Pressure rating according to ASME B16.5 standard:

According to this standard, steel flanges and their alloys are divided into classes 150-300-400-600-600-900-1500-2500.
