Does the roughness of the flange surface have a big impact on the sealing effect?

Flanges have good working capabilities, can meet the quality requirements of pipeline connections, and must comply with product protection, safety regulations and technical specifications, and bulk density. The ratio of the true density of the product nozzle to the total volume refers to different pores, excluding other volume openings at the tail, and the pipe port is closed. The connection is tightened, and the other end is connected to the outside. It can be safely at room temperature and constant pressure. The gas passes through the pipe capacity, usually The moisture permeability coefficient is measured by the large-diameter flange material, using fireproof, high-temperature materials, good sealing performance, and some common steel-resistant materials and hot metals. Reasonable selection of materials plays an important role in ensuring the quality, safe and economic operation and service life of high-quality flange products.

Since stainless steel data is widely used in the production of flanges, the need for such data flanges is too great. This is also very good news for manufacturers. Although production is very important, the quality seems to be greater. Manufacturers are required to do a good job of ensuring the effect of use when producing stainless steel flanges. It is important to avoid simple corrosion of stainless steel flanges caused by materials. The message of stainless steel flanges is to insist that its appearance is clean. Once corroded, the appearance of stainless steel will change instead of being so bright. Therefore, those who have the ability to corrode stainless steel should stay away from production.

The roughness of the flange surface has a great influence on the sealing effect, especially when using non-gaskets, it has a significant influence on the sealing effect. The roughness of the sealing surface is one of the main reasons for leakage. For example, the flange surface of the rotating knife is spiral, and metal gaskets are used. If the roughness value is large, the gasket cannot block the knife shape formed by the spiral groove. Under pressure, the medium will leak along the groove. The soft gasket is easy to deform and block the operating knife mode, and it is necessary to reduce the finish on the flange surface to prevent leakage. For gaskets, the flange surface is too smooth because the interface density is reduced, so it is not desirable.
