HG/T3112-1998
This standard is a revision of the original standard HG51320-80 of the Ministry of Chemical Industry. This standard is not equivalent to the sample of SIGRI Company of Germany.
This standard adds the scope, reference standards, test methods and inspection rules. In the product classification chapter, the specification series in the original standard is greatly supplemented and improved. Among them, the graphite heat exchange tube has been expanded from the original thin tube (@32/022) equipment series to a thick tube (@50/Q36) equipment series, with a heat exchange area of ​​160~660 square meters. The heat exchange area of ​​the thin tube series has been expanded from the original 5~260 square meters to 5~810 square meters. At the same time, the specifications, models, requirements and other contents have also been modified accordingly. The industry standard HG2370-92 "Technical Conditions for Graphite Chemical Equipment" is the general technical conditions for graphite equipment. When implementing this standard, it should be implemented together with the HG2370 standard. When the equipment belongs to a pressure vessel, the processing and manufacturing should comply with the relevant regulations of the pressure vessel. From the date of implementation, this standard will replace HG5-1320-80. This standard was proposed by China National Chemical Equipment Corporation and is under the jurisdiction of the National Technical Committee for Standardization of Non-metallic Chemical Equipment. The responsible drafting unit of this standard: Shenyang Chemical Machinery Factory The participating drafting units of this standard: Nantong Carbon Factory, Dalian Potassium Fluoride Factory Tai'an Qianwei Carbon Products Factory, Chemical Industry Ministry Chemical Machinery Research Institute. The main drafters of this standard: Shi Jiabi, Bai Wangrong, Wang Fuquan, Han Zhenting, Song Zhiyi. Scope

3.1 The structural form is shown in Schematic 1 (the upper and lower heads of the heat exchanger can also adopt a lining structure). 3.2 The heat exchanger is divided into two types, A and B, according to the diameter of the graphite heat exchange tube. The diameter of the A-type heat exchange tube is Φ32/Q22, and the diameter of the B-type heat exchange tube is 050/Φ36. The effective length of the heat exchange tube is divided into 2 meters, 3 meters, 4 meters, 5 meters, and 6 meters, with a total of five specifications. The specifications and models of the heat exchanger are shown in Table 1. 3.3 The connection and use of the pipe mouth are shown in Table 2.
3.4 ​​The installation dimensions are shown in Table 3.
3.5 Marking
The Ministry of Chemical Industry of the People's Republic of China approved on March 17, 1998, and implemented on October 1, 1998.
