Today Tiger Steel will provide you with information about Flange DN65. Let’s follow along!
Oil and gas plants & their pipeline system is a complex system with pipelines that can span thousands of kilometers.
Flange DN65 or any flange or accessory product. For the system to work correctly and smoothly, choosing the right flanges and accessories is extremely important.
Flanges must completely match the joints on the pipeline. To make sure they can properly perform their functions. Because even a small mistake in the flange selection process can affect the entire rear system chain.

Factors to consider when choosing flanges DN65 for your project
As Tiger Steel said a lot in previous posts. Flanges in each standard and each pressure level have different specifications. And so is the flange DN65.
To make the right choice, you should note the following points:
Flange drawing
4. Production Standard. There are many industry-defined manufacturing standards from which you can choose flanges. Because there are many projects that only accept materials from a specific standard.
5. Pressure level. The pressure class indicates the margin of pressure that the flange can safely operate and maintain. Each standard comes with available pressure levels, from high to low-pressure capacity. The pressure level of the products connected to the flange should be the same as the pressure level of the valve and the pipeline in use.
6. Manufacturing materials. The choice of material for flanges depends on the understanding and application that the elements will be encountered in an application where the piping system is being used. The most common materials include chrome, nickel, carbon steel, duplex steel, stainless steel, and more.
