At the 2018 China Refrigeration Exhibition, Totem Refrigeration is coming!

2022-12-05

On April 9, 2018, the 29th International Refrigeration, Air Conditioning, Heating, Ventilation and Food Refrigeration Processing Exhibition (referred to as "China Refrigeration Exhibition 2018") was held in Beijing.

This exhibition has the theme of "Improving Quality and Efficiency, Balanced Development, Staying True to the Original Intention, and Creating the Future Together". The total exhibition area is 106,800 square meters, and the net area reaches 46,431 square meters. Up to now, a total of 1,141 companies from more than 30 countries and regions have participated in the exhibition. Famous companies and elite businessmen from home and abroad gathered on site.

Shandong Totem Refrigeration Equipment Co., Ltd. displays our new products at booth E2G65 and actively gives back to new and old users.

Shandong Toteng Refrigeration Equipment Co., Ltd. is a refrigeration high-tech enterprise integrating the development, design, manufacturing, sales and installation of refrigeration equipment compressor units and pressure vessels.

The company is located in Fengcheng Industrial Park, Laiwu District, Jinan City, with convenient transportation and beautiful environment. The company has first-level and second-level pressure vessel design and manufacturing qualifications and GC2 pressure pipeline installation, modification and maintenance qualifications. And mechanical and electrical equipment installation engineering qualifications. The company has now passed three certification systems: ISO9001 quality, ISO14001 environment, and radiation safety. And obtain the manufacturing license for refrigeration equipment. It is the deputy director unit of Shandong Refrigeration Society and a member unit of China Refrigeration Society. It has been recognized as a provincial-level integrity demonstration unit, a provincial-level advanced quality management unit, and one of the top ten honest enterprises in China's refrigeration industry in 2013. The head office cooperates with many well-known domestic universities in development and research, and is the cooperation and exchange base of the Educational Science Institute of Shandong Vocational and Technical College of Commerce. Every year, some professional elites are assigned to the company to engage in development and research work. We have a group of experienced and high-level professionals in all key control links such as design, technology, welding, heat treatment, manufacturing, testing, and measurement; we have a group of well-trained personnel who can engage in х-rays, γ-rays, ultrasonic, We have a team of non-destructive testing personnel for magnetic particle and penetrant testing; we also have a team of highly skilled welders who have obtained the special equipment welder professional qualification certificate issued by the Shandong Bureau of Quality and Technical Supervision, and can engage in welding of special materials in various positions and with high difficulty. ; The company has complete technical equipment and advanced testing methods, including forming equipment, cutting equipment, various welding equipment, non-destructive testing equipment, physical and chemical testing equipment, heat treatment equipment, lifting equipment, metal cutting machine tools and forging equipment, which can fully meet the requirements of pressure vessels. Manufacturing and testing needs.

The main refrigeration equipment produced includes shell and tube condensers, pressure vessels for ammonia and fluorine systems, barrel pump units and other products. Pressure vessels include complete sets of refrigeration containers and chemical containers (heat exchangers, towers, autoclaves, vulcanization tanks, gas generators, etc.), high and low pressure gas storage tanks, and air buffer tanks.

What is a pressure vessel

1. The maximum working pressure is greater than or equal to 0.1Mpa.

2. The product of working pressure and volume is greater than or equal to 2.5Mpa·L.

3. The containing medium is gas, liquefied gas and liquid with the maximum working temperature higher than or equal to the standard boiling point.

Generally speaking, as long as item 2 is met, it can be determined as a pressure vessel.

Pressure vessel manufacturing

1. The manufacturing process of pressure vessels can generally be divided into: raw material acceptance process, scribing process, cutting process, rust removal process, machining (including planing, etc.) process, rolling process, assembly process, welding process (product welding test) board), non-destructive testing process, hole scribing process, general inspection process, heat treatment process, pressure test process, and anti-corrosion process.

2. Different welding methods have different welding processes. The welding process is mainly determined based on the material, grade, chemical composition of the workpiece to be welded, the structural type of the weldment, and the welding performance requirements. First of all, the welding method must be determined, such as manual arc welding, submerged arc welding, tungsten arc welding, gas metal arc welding, etc. There are many types of welding methods, and they can only be selected according to specific circumstances. After the welding method is determined, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode model (or brand), diameter, current, voltage, welding power source type, polarity connection method, welding Number of layers, number of passes, inspection methods, etc.

carbon dioxide storage tank

Carbon dioxide storage tank, low-temperature liquid carbon dioxide storage tank, is a double-layered container composed of inner and outer containers. It is a vacuum powder insulation type. It can be divided into two types: discrete and horizontal. The inner container material is 16MnDR, and the outer container material can be different according to the user's region. Choose Q235-B or 16MnR. The inner and outer containers are filled with insulating material pearlescent sand and evacuated (divided into vertical and horizontal types).
