ភាសាខ្មែរFlange DN80 is one of the extremely important accessories to connect pipes together. On the market and in most construction projects, cast steel pipes and welded steel pipes are used for construction.
There are mainly two types of flanges used:
- Carbon Steel Flange
- Stainless Steel Flange (Inox)
To understand the specifications of Flange DN80 clearly, please read the short article below!

Applications and Benefit
Applications of Flange DN80
Depending on the design, the Application and Benefit of the theme may be different.
Example:
- The blind flanges are used to seal the end of the pipeline.
- The internally threaded flange is mainly used to reduce the pipe size
- Flanges with weld necks are mainly used for high-pressure equipment.
and many more uses.
Benefit While We Collaborate On A Project
In my opinion, if you would like to optimize the cost & profit of the construction, you should ask your expert before placing the order.
Because, maybe with a lot of tons information about this industry, A newbie will be confused.
No worries about that. You can ask suppliers, which co. operate can provide a catalog of Flanges.
By the way, our experts always support loyal customers with their experience. Absolutely Free.
Such as, We can replace Flange DN80 with another Standard with the same specifications.
Hopefully, the knowledge about Flange DN80 that Tiger Steel provided above will be useful to you.
If you need to buy steel flanges, you can contact Tiger Steel.
In addition to flange products, Tiger Steel trades in black steel pipes, galvanized steel pipes, black box steels, galvanized Hoa Phat, SeAH, …; cast steel pipe, large diameter steel pipe. Steel pipe fittings of all kinds, fire protection accessories, …
