With the revision and improvement of a series of industry standards such as “Technical Regulations for Domestic Hot Water Systems”, the manufacturing industry of domestic hot water equipment is facing stricter norms and requirements. The new national standard not only elaborates on the core indicators such as the pressure-bearing performance, insulation effect, and water quality hygiene of hot water equipment, but also significantly raises the testing standards. For instance, it stipulates that the hot water tank must pass a 1.2 times rated pressure test, and the heat loss of the insulation layer must not exceed 0.5℃/h. This poses even greater challenges to the production processes and quality control of enterprises.
Facing the upgrade of industry standards, Hengrui high-pressure water tanks have stood out in the market competition by virtue of their mature manufacturing process and strict quality control system. In the production process, Hengrui adopts advanced technologies such as fully automatic laser drilling and fully automatic straight seam welding to ensure product accuracy and quality stability. The inner liner of each water tank must undergo pressure testing above the national standard (for example, pressurizing a water tank with a rated pressure of 4 MPa to 6 MPa for testing and ensuring no leakage after holding pressure for 30 minutes) to pass. Meanwhile, in terms of insulation performance, Hengrui selects high-quality insulation materials and uses unique techniques to ensure uniform density of the insulation layer. Before leaving the factory, multiple rounds of insulation performance tests are conducted. With an ultimate pursuit of quality, Hengrui high-pressure water tanks fully meet the industry’s high standards, providing safe, reliable and high-performance hot water equipment for large hotels, construction sites and other scenarios, and promoting the industry to move towards high-quality development.
