Best PL flange is a commonly used component in pipeline construction. Because PL flange has many advantages in the process of use, it is widely used. I believe everyone is very curious about flat welding flanges. Flat welding flanges have What characteristics, let us take a look!

Although Best PL flange has certain advantages in actual use, its shortcomings are also obvious. Due to some defects in its own design, it is difficult to ensure that flat welding flanges will not leak during connection. The following is the flat welding flange design Some defects in the connection are dynamic. Periodic loads (such as thermal expansion and fluctuations) will cause movement between the flange and the plane, which will affect the function of the flange and the flange, thereby destroying the integrity of the flange, and ultimately Cause a leak.

It is impossible for any product to be defect-free, and the shortage of products can only be controlled to a minimum. Therefore, as long as the production process of Best PL flange is continuously improved, the performance of flat welding flanges can be effectively improved, and leakage can be avoided as much as possible. Play the biggest role in welding, flat welding flange not only saves space and weight, but also has good sealing performance to ensure that the joint will not leak. The compact structure leads to a smaller flange size and a smaller sealing diameter. The flange gasket has been replaced with a sealing ring to ensure the matching of the sealing surface, so that only a small amount of pressure is needed to press the cover tightly. As the required pressure decreases, the size and number of bolts are also reduced, and the final design A new product with small size and light weight (70% ~ 80% lighter than traditional flanges) has been developed. Therefore, the flat welding flange is a relatively high-quality product from France and Lan, which reduces the quality and space. Played an important role in the application.

The sealing principle of Best PL flange The two sealing surfaces of the bolt press the flange gasket together to form a seal, but this will also cause the destruction of the seal. In order to maintain the seal, a large bolt force needs to be maintained, so the bolt must be made Larger and larger bolts must be equipped with larger nuts, which means that bolts with a larger diameter are needed to create conditions for tightening the nuts. However, the larger the diameter of the bolt, the less applicable the flange, and the flange is likely to bend. The only way to do this is to increase the wall thickness of the flange section.

These are some of the characteristics of Best PL flange. Although the design of Best PL flange has some shortcomings, as long as the production process meets the standards, there will be almost no leakage of flat welded flanges. Flat welded flanges have many advantages in the construction process. The flat welding flange has become a widely used flange.
