What is a large flange? Large flange is a type of flange used in large-scale engineering. Generally, large flanges have a relatively large load-bearing capacity, and we have found that they are generally not easily deformed. Of course, the most important thing to pay attention to for large flanges is their thickness. When making large flanges, both the inner and outer diameters are not a problem, and the thickness is the biggest headache for the master. Large flanges that are too thin can easily deform. Of course, there is usually no deformation problem during the production process. We can use machine tools to handle it, but it can be a bit dangerous during use.

How to make a large flange? What is the difference between a regular sized production?

The teacher explained to us that we can first cut the material into Flat noodles with a medium plate, then roll it into a circle, and then process the waterline and install bolt holes. This way, a large flange can be made, with a maximum length of 7 meters! This type of flange has good guarantee and is also very reassuring to use.

Because the raw material is medium plate, the density is also very good. And the materials are classified into carbon steel, stainless steel, and alloy steel. The products of large flanges are all welded products without screw threads.

What happens when the sealing joint is not tight? The direct result is leakage. In various industries' pipelines or devices, the sealing failure of flange joints may cause serious consequences, such as energy and material waste. If a lot of materials are wasted, in severe cases, it can lead to equipment scrapping, even human casualties and other accidents, thereby causing environmental pollution.

Many related industries, such as petroleum, chemical, atomic energy, and aerospace, have put forward requirements for sealing of pipeline devices. The flange itself is a detachable accessory, and its sealing degree is very high! However, we also need to pay attention to sealing materials, as the quality of sealing materials directly affects the quality of flange products
