If you want to ask what the best sealing flange is, the top ranked flange is definitely a flat welded flange!
We all know that flat welding flange is a type of flange, so is the sealing performance really good as claimed? Experts explain that flat welding flanges have the best sealing performance! How was that achieved? Is there any reason for this? Today, let me talk to you about its sealing principle.
The commonly seen flat welding flanges have bolts, which is not surprising, but it can indeed enhance sealing performance! Most of the flat welding flanges we see have bolts, which is why flat welding flanges can seal. Why can flat welding flanges be sealed? We have noticed that flat welding flanges have bolts that can cause the two sealing surfaces to compress each other, thus achieving a sealing effect!
Flat welding flanges also have gaskets! And the sealing is not poor. Moreover, flange gaskets can also enhance sealing performance, thereby achieving a sealing effect. What force must we use to maintain sealing? Yes, the function of bolts! A huge bolt force can enhance thrust, so bolts need to be made very large. That's why the flange bolts we see are very large. And large bolts need to be matched with large nuts, so it is often seen that bolts with larger diameters are used to tighten the nuts.
What other accessories are there? Bolt! We can enhance the bearing capacity by using bolts! Why is it better to have larger bolts? Because a larger diameter is better, it can increase the wall thickness of the flat welding flange and increase its load-bearing capacity. So when producing flat welding flanges, try to improve the performance of the product as much as possible to maximize its effectiveness.
That's why we see flat welded flanges with large thickness, compact bolts, and high load-bearing capacity.
