The tubular heat exchanger, the flat tube head, is not just the outer shell. Instead, each row of tubes is connected to the shell through the tube plate. This is a game of space and energy, and it is also a test of the patience, meticulousness, refinement, and professional ability and strength of a seasoned welder, a lathe operator, and a grinder in designing and manufacturing heat exchanger solutions.
Zhengzhou Chenkai International, based on the scheme provided by the global heating district for using plate-type heat exchanger units, aims to clarify the normal operation process of the unit, standardize on-site debugging operation standards, identify equipment and installation hazards, ensure the long-term stable, efficient and safe operation of the unit, meet the winter heating needs of the district residents, and follow the relevant specifications of "Plate Heat Exchanger Unit" (GB/T 28741-2012) and heating system construction and acceptance.
Test pressure and medium Test pressure value: Hydraulic test pressure: Usually 1.25 times the design pressure (or as specified in the drawings and standards). Separate tests must be conducted for the tube side and the shell side. When testing one side, the other side must remain open to the atmosphere to observe if there is any internal leakage. The pressure value should be corrected for temperature according to the design pressure and temperature of each side, using the standard formula (since the tests are usually conducted at normal temperature). Test medium: First, conduct a clean water (hydraulic test). If the design temperature is too high, consideration may need to be given to the compatibility between the water temperature and the material. For equipment that cannot be filled with liquid or where even a small amount of residual liquid is not allowed, an air pressure test can be adopted. However, this method is highly risky and has extremely strict safety requirements. Usually, a special plan is needed and it must be approved.
Wound tube heat exchanger is a core equipment forWound tube heat exchanger in Dairy Product Processing.
In modern dairy processing plants, a sophisticated stainless steel piping system operates at a rate of processing tens of thousands of liters of milk per hour, yet its energy consumption is nearly one-third lower than that of traditional equipment. This is the real transformation brought about by the spiral-wound heat exchanger in the dairy industry. In the core part of dairy processing - the heat treatment process, the spiral-wound heat exchanger, with its unique spiral-wound design, achieves efficient heat exchange and excellent hygiene safety, becoming a landmark equipment for the upgrading and transformation of the dairy industry.

In recent years, the fermentation industry, as an important field of bioengineering, has achieved remarkable accomplishments. From the brewing of alcoholic beverages and soy sauce in food processing to the production of antibiotics in biomedicine, the application scope of fermentation technology is constantly expanding. However, during the fermentation process, temperature control has always been a key challenge. Both excessively high and low temperatures can affect the growth and metabolism of microorganisms, thereby influencing the quality and output of products.
In the previous finished product transportation process of Chenkai, most of the products were packaged with stretch film to protect the products from damage caused by bad weather and road conditions during transportation. However, during actual use, it was found that in some harsh transportation conditions, the degree of protection provided by stretch film packaging still has deficiencies. Therefore, Chenkai has launched a full-line packaging upgrade plan.
With the demands for refined, accurate and constant temperature control in the heat exchange process in fields such as fine chemicals, food and pharmaceuticals, Chenkai International Trade Co., Ltd. has promptly responded to the needs and intensified the development and production of intelligent temperature control units.
