The sealing form of CC2F force transfer joint is actually so complicated?

The arc is induced 10 mm before the arc pit, pulled to the arc pit, and the arc pit is filled by swinging laterally along the shape of the arc pit, so that the weld seam coincides with the contour line of the arc pit, and when the swinging width reaches the width of the weld seam, it is kept down and welded normally. CC2F force transfer joint should move quickly, be agile and skillful, and avoid disconnections. From the viewpoint of fluid mechanics, CC2F force transfer joint is a throttling element whose local resistance can be changed, i.e., by changing the throttling area, the flow rate and kinetic energy of fluid can be changed, resulting in different pressure loss, thus achieving the purpose of pressure reduction.

Then it relies on the adjustment of the control and regulation system to balance the fluctuation of pressure of CC2F force transfer joint with the spring force, so that the pressure of CC2F force transfer joint can be kept constant within a certain error range. When the medium pressure inside the equipment or pipeline rises above the specified value, it is a special valve that prevents the medium pressure inside the pipeline or equipment from exceeding the specified value by discharging the medium outside the system. Due to the high cleanliness required by high-purity gas piping.
 
In order to reduce the welding workload at the installation site and ensure the cleanliness, so the construction of the pipeline is first prefabricated in a prefabricated room of class 1000, the construction personnel should wear clean clothes, the CC2F force transfer joint used should be guaranteed clean, in addition the construction personnel should have a strong sense of cleanliness, and the construction process should minimize the pollution of the pipeline.
The pipe should be cut out with the end face perpendicular to the pipe axis, and measures should be taken to avoid the pollution of the inside of the CC2F joint by the outside dust and air when cutting the pipe.
