Condenser quality appraisal

The condenser is a component of the air conditioning system. It can transfer the heat in the pipe to the air near the pipe very quickly. Most cars are placed in front of the water tank. A device that converts gas or vapor into liquid.
Power plants use many condensers to condense the steam discharged from turbines; condensers are used in refrigeration plants to condense refrigeration vapors such as ammonia and Freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors. In the distillation process, the device that converts vapor into liquid is called a condenser. All condensers operate by removing heat from gases or vapors.
In the case of condenser quality appraisal, Zhongke Testing can provide condenser quality appraisal services.

condensers can be divided into three categories: water-cooled, air-cooled, and evaporative types according to their different cooling media.
water-cooled condenser can be divided into two types according to its structure: shell-and-tube condenser and jacket-and-tube condenser.

In a certain year, a chemical company as Party A and a defendant company as Party B signed a "Contract" on the purchase of condenser equipment. After it was actually put into use, Party A discovered that the weld between the tube plate and the tubes at the bottom of the condenser was leaking. The actual use time was 23 days. After returning to the factory for repairs, the condenser was punctured again. The plaintiff, a chemical company, filed a lawsuit.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the condenser involved in the case.
appraisal analysis results: The
appraisal analysis expert team made the following suggestions and conclusions based on the data of the circumferential weld of the condenser involved, fatigue blasting test and blast fracture analysis:
The root of the weld of the condenser involved in the case has defects such as lack of penetration or lack of fusion to varying degrees, and there are quality problems.
