In the competitive industry market, stainless steel manufacturers want to go deep into the core area, so that the work of the initial information inspection of the industry market can not be lacking, that is, it is particularly important; Only when we fully grasp the information about the trend and form of the consumer market, can we compete for market position with more confidence.
Therefore, while deeply mining information, it is also necessary to achieve quality control, so when processing the size of the stainless steel head, what are the reasons to avoid cracking
Processing technology of large and small heads
The process of stainless steel processing to avoid cracking is basically based on pressure, but the pressure link will promote the strength and relative density of the steel to increase, and it is not known that if you do not go through the heating, it will be more prone to cracks.
Change the control of the area, under normal circumstances, the size of the first processing area is within one level, for example, the size of 320-137, basically need to use after many times of heating treatment, at first the 320 steel pipe to suppress a head, the 320 aperture to suppress 273, this time also need to use after heating
Changing again is the link of 273 changing 219, this time it is also necessary to heat the steel pipe to the specified temperature and then suppress it. Then it is the link that 219 changes into 137, and each change mainly requires heat treatment.
All kinds of materials have different strength and compressive strength and other characteristics, so it is decided that the pressure strength of each material is different, the same model of the size of the head, the material of different processing forms and processes will be greatly different, for example, the size of the ordinary carbon steel head will be shaped after 3 heat treatment, As everyone knows, the larger the strength of the size of the alloy material, the more frequent the pressure and the frequency of heating, and the more complicated the shaping process.
Stainless steel hair small head type
Concentric stainless steel size head is used on the vertical tube, eccentric stainless steel size head is used on the horizontal tube, and the bottom or top should be marked when used.
When the flow of liquid in the pipeline changes, the flow requirement is not too large when the stainless steel size head is used. Especially in the installation of the reducer pipe at the pump inlet, in order to make the gas not accumulate at the reducer
To avoid cavitation caused by errors in the installation process, the horizontal inlet pipe of the pump uses an eccentric stainless steel size head to prevent cavitation.
Therefore, when the horizontal inlet pipe of the pump is reduced, the eccentric stainless steel size head is used to match well with the joint of the control valve, flow meter and other instruments. When the pipe is fed horizontally from top to bottom, the bottom level should be selected
