What is the most commonly used flange?
The High-pressure flange is a common pipe-end connection part in the construction of large pipelines, this part can prevent the impact of a high-pressure environment on the pipe-end connection, the high-pressure flange is more than the flange of the relevant national departmental standard size regulations, and usually refers the flange of DN2000 or more, the maximum size of the flange in the national flange standard GB/T9119-2000 DN2000, the flange is produced because of The constructor has not formulated it, there are two kinds of production technology of forging and coiling, these two production technologies are forging and coiling, the cost of coiling flanges is slightly lower than forging, but some oversized flanges can not be forged, the theoretical weight of the product, the material has stainless steel, carbon steel, and alloy steel, it made of different materials have different characteristics and are suitable for different use environments.
High-pressure flanges must pay attention to transportation matters at the time of delivery
Highway and general viaduct limit height of 4.5 meters, the flange itself is 3 meters in diameter, plus the truck itself is about 1.5 meters high and can not be crossed, in the lateral handling, 3 meters of large flange also exceeds the width of the driving lanes, if the distribution problem is not solved, the transportation will be very difficult, so you need to pay attention to this point when transporting.
I believe that we are very interested in forging high-pressure flanges, so what exactly do we need to pay attention to when forging high-pressure flanges, and what is the process like? Take a look at this knowledge about forging flanges!
Mold forging after punching, bore size in the mold making when leaving the size, fastening bolt holes in the forging is almost open, generally, no bolt holes protruding into the domestic design, of course, must be processed flange fabric. Cannot be forged only on the above bolt holes and sealing surfaces. Must be processed by lathe, in the production process must pay attention to the removal of stress from the casting, if not removed, the casting may not be solid, so the production of the secondary flange needs to be processed.
How to maintain flanges?
They are often exposed to higher pressures, so it is important to maintain them effectively when using such a part. Companies need to understand all the factors and various data that may occur with flanges.
Summarize: the above is some knowledge about it, I hope these contents can help you better understand it, of course, we need to know that it is suitable for some high-pressure environments, although in the ordinary environment can also use it, there is no need for this, we should choose the flange according to the project requirements, in the choice of it should also pay attention to the qualification of the manufacturer When choosing high-pressure flanges, you should also pay attention to the qualification of the manufacturer so that you can choose the right flange parts.
