First of all, because carbon steel and water long-term contact will rust, the appearance will change, so we should not put carbon steel flanges in wet and cold areas
In addition, the mechanical properties will also be relatively changed, so we should avoid as much as possible to prevent a lot of inconvenience to everyone.
The use of carbon steel flanges
Then we also need to pay attention to not using hard objects to impact the carbon steel flange itself, so that the appearance of the carbon steel flange will be black and blue, serious if it will destroy the sealing surface, so that the future seal is unstable
The rise of all kinds of new objects in the flange continues, and the development trend in this kind of steel pipe industry also continues to create high kinds of objects to sell steel pipes
In fact, carbon steel flanges are also gradually developing in the scope of steel, so what is the application of carbon steel flanges in construction projects
Large carbon steel flanges should be based on the corresponding conditions and areas and the use characteristics and competitive advantages of its carbon steel flanges for different use areas
Play a key role and value in the use and construction. If the use is not good, it is very easy to cause the flange manufactured by the flange manufacturer to crack.
In pipeline engineering, flat welded flanges are mainly used for pipeline access, and high pressure flanges are mostly butt welded flanges. In view of the need for pressure resistance function, they have the characteristics of not easy to change, good sealing characteristics and wide application fields.
The flange has a more complex flared structure, its characteristics are stiffness and elasticity in relative provisions, reasonable welding thinning transition period, welding gaps avoid joint
Carbon steel flange processing technology
It is manufactured and produced by different methods and processes in the actual production and development process. Forging method, roller method, rolling method and bulging method are four common production methods of carbon steel flanges.
The forging press is used to push out the end or part of the pipe to expand the outside diameter of the flange. Torsion type, connecting rod type and roller type are common type forging machines
The outer circumference of the core check valve placed in the tube is pushed by a roller, which is used for round edge processing. The roller method usually does not require a mandrel and is suitable for the inner rounded edges of thick-walled pipes
One is to put rubber into a pipe and compress it into shape with a punch above it, and the other is hydraulic bulge forming, in which the middle of the pipe is filled with liquid and the liquid is then pressured to drum the tube into the desired shape. These two are called the bulking method.
