Have you ever wondered what a blind flange is and what it is used for ? To understand once and for all, our team prepared this article!
Before understanding the usefulness and application of a blind flange , let's go over the basics:
Flange, what are they:
Flanges are components used to connect pipes. They are usually installed in pairs and secured with bolts. Because the pressure is high, the flanges are joined together, sealing any potential leaks.
So, what is a blind flange?
Blind flanges are fully sealed and lack a central hole. They have this characteristic because they are used in pipe terminations, and they have specific applications that highlight their use.
Main applications of blind flange:
- Pipe terminations: The blind flange is commonly applied to pipe terminations, thus sealing the assembly.
- In-line maintenance and cleaning: The blind flange is applied along some pipelines to facilitate subsequent maintenance on the system, allowing it to be opened, maintenance carried out and then closed again.
- Waiting for pipeline expansions: The blind flange is also used in waiting situations, where new sections for complementary pipelines will be connected in the future.
Furthermore, blind flanges stand out for their high resistance to pressure and temperatures, making them widely used.
Use of blind flanges:
Blind flanges are generally used in the following industrial segments:
- Power plants;
- Industries and production in the most varied segments;
- Engineering projects;
- Oil companies;
- Companies that carry out cement and mining work;
- Water, chemical and gas supply sector;
- Construction sector.
- We hope you now understand what blind flanges are and what they are used for.
