What are the three main reasons for the unsatisfactory application effect of semi volumetric heat exchanger
>>>
1. The structure of the semi volumetric heat exchanger is unreasonable: the semi volumetric heat exchanger must be assembled according to the actual application needs of users and project working conditions when it leaves the factory in accordance with the national requirements. In order to save costs, some manufacturers do not lead the team according to the national requirements., The heat exchanger can only achieve the effect of heat conversion and follow the law of energy conductivity. The heat released from the hot side is equal to the heat absorbed by the cold side. Generally, the heat from the heating system on the hot side is taken away by the cooling water on the cold side that does not meet the requirements. If the water volume and water temperature are not good, the temperature on the hot side will not drop, so no matter how big the heat exchanger is, the effect will be poor.
What are the advantages and disadvantages of spherical tanks

What are the advantages and disadvantages of spherical tanks
Advantages: 1. Under the condition of the same volume, the ball surface has a very small surface area and the net weight of the equipment is very small; 2. The small surface area of the sphere means that the heat transfer area is very small. In addition, the interlayer can be vacuumized, which is conducive to good heat insulation effect; 3. The spherical characteristic has good resistance to internal and external pressure
Disadvantages: 1. Special processing tools are required for processing and forming, and the processing accuracy is difficult to guarantee; 2. The on-site assembly technology is difficult and the quality is difficult to guarantee; 3. Although the net weight of the spherical shell is very small, the material utilization rate is very low.

Pipeline installation requirements
>>>
Pipeline installation requirements:
1. Before pipeline installation, the equipment nozzle, embedded parts, reserved holes, steel structure and other contents related to pipeline installation shall be reviewed.
2. The gradient of the pipeline shall be adjusted according to the requirements of the drawing. The support can be used to meet the gradient requirements. The welding seam shall be set at the place convenient for maintenance and observation.
