Identification of the cause of the rupture of the heat exchange pipe

Heat exchange tube is a device that transfers heat between two different fluids through a pipe. In layman's terms, it is a heat transfer tube. Heat exchange tubes are widely used in industrial fields. Their main function is to transfer heat from one fluid to another fluid. Common industrial application scenarios include cooling water circulation systems, steam distribution pipeline systems, heat exchange in petroleum and chemical processing, etc.
In the case of heat exchange tube rupture cause identification cases, Zhongke Testing can provide heat exchange tube rupture cause identification services.

1. Equipment aging
As the use time increases, the heat exchange tubes inside the equipment will also gradually age, leading to an increased risk of breakage.
2. Improper operation
The operator's improper operation, misoperation or negligence of the equipment can also cause the heat exchange tube to break. For example, during loading, unloading, maintenance, cleaning, etc., if the inlet and outlet valves are not closed in time or are operated improperly, or even the pipes are forcibly pulled, etc., the pipes may be damaged.
3. Material quality
The material quality of the heat exchange tube is also a cause of tube breakage. If the materials used are of unqualified quality, have poor corrosion resistance, or have not been strictly inspected, it will bring certain risks to the use of the pipeline.
4. Thermal expansion and contraction
In fluid movement, the heat exchange tube will expand after being heated and shrink again after cooling. This thermal expansion and contraction will produce a certain stress on the pipe. If the stress exceeds the limit of the material, it will cause the pipe to break.

A set of heat exchangers purchased by a polymer company. The heat exchanger pipes ruptured during operation, resulting in a dispute with the equipment manufacturer.
was entrusted by the court to undertake the identification and analysis of the cause of the rupture of the heat exchange tube involved in the case.
appraisal analysis results:
appraisal analysis expert group discussed the relevant information and on-site investigation of the heat exchanger pipeline involved in the case and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions: HTMLTAG The reason for the rupture of the TOKEN4 heat exchanger pipe is that there is no buffer tank installed between the plunger pump and the heat exchange tube. The pulse vibration and impact generated by the operation of the plunger metering pump cause the heat exchange tube to undergo repeated lateral and axial displacement, friction, impact, and deformation, which eventually leads to rupture and leakage.
