The use of steel flanges in pipes and industrial processes is essential to optimize maintenance and repair tasks when necessary; therefore, knowing that there is a wide variety of these accessories on the market makes it essential to know the characteristics of each one. , as well as the use, exposure, pressure, and other factors to which it will be subjected, to choose the correct one, here they talk about these important aspects

In installing pipes or industrial processes, maintenance is essential and, in turn, is a factor that requires flexibility in the system. Flanges are those accessories used to provide versatility when mounting or dismounting pipes and thus offer speed and efficiency in the processes. This article explains what these elements are, the variety that exists, and the different characteristics that make them unique and indispensable pieces for the industry.

What are flanges?
Flanges are elements made of stainless steel, carbon steel, and others, which have the function of joining connections and accessories in different systems, whether in pipes, valves, pumps, boilers, or heat exchangers. Experts of steel flanges say that thanks to these accessories, time and cost in industrial processes can be reduced, which represents great savings for companies.

One of the main variations in flanges is that they can come already attached to a part, for example, to a valve or pump, or separately. In the latter, there are different types, which have holes in their circumference for the use of union bolts that help to connect the pieces.

Flange types
To talk about the types of steel flanges in the market and select the most appropriate one, it is necessary to know the use they will receive and the conditions in which they will be exposed.

Carbon steel flanges like A234 WP22 are special for normal services with moderate temperatures, and corrosion resistance is not relevant.

But on the other hand, if the environment where the flanges will be exposed is more severe, and the pressure and temperature are high, then special steel or alloy flanges are the best options.

SO (slip-on) or sliding flange: they are also known as neckless flanges, and their characteristic is that it makes it possible for the outside of the tube to be inserted without problems inside the flange. It is used for pipes with low pressure and normal conditions. You can easily get them from slip on flange manufacturer.
WN (Welding Neck) flange with welding neck: this type of flange has two designs, one with a high conical neck and the other with a narrow conical neck. The main aspect of neck flanges is that they can be welded directly to the pipe. Among its main applications are those services with exposure to high temperatures, pressure, or corrosive or flammable products. One of the most popular types of WN flange is Hastelloy C276 Flanges.

Blind flange: it has the main function of sealing the end of the pipes to block or stop the flow. Therefore it does not have a hole in the center. Its application pressure capacity is very high.

Lap joint flange or LP (Lap Joint): the ideal type of flange for applications where pipes require high resistance to corrosion since its design allows it not to have contact with fluids.Inconel 625 Flanges is one of the most popular Lap Joint Flange.
