This standard is a revised version of HG5-1321-80YKA type circular-block graphite heat exchanger". This standard is revised and arranged according to the actual situation of domestic circular-block graphite heat exchanger products in accordance with relevant standards such as GB/T1.1-1993 and HG2370-92.
This standard adds the scope, reference standards, test methods and inspection rules, etc., adds the basic structure in the product classification chapter, and also makes corresponding supplements to the specification series of YKA-type products with the same technical requirements. The industry standard HG2370-92 "Technical requirements for stone-made chemical equipment" is the general technical conditions for stone-made equipment. When implementing this standard, it should be implemented in conjunction with the HG2370 standard. When the equipment is a pressure vessel, this standard will replace HG5-1321-2000 from the date of implementation. This standard was proposed by China Chemical Equipment Corporation. This standard was promoted by the National Non-metallic Chemical Equipment Standardization Technical Committee. The manufacturing of this standard should comply with the relevant provisions of pressure vessels. The drafting units of this standard are: Nantong Yangzi Su Co., Ltd., Shanghai Carbon Decay Factory, and Chemical Machinery Research Institute of the Ministry of Chemical Industry. The main drafters of this standard: Li Ruiqing, Bai Wangrong, Shu Meiling Www.bzSOsO.cOm1

Methods, inspection rules, and marking, packaging, and other similar differences (hereinafter referred to as heat exchangers). When other similar differences are published, the versions shown are valid. Same performance.
3.1.2YKA type round hole graphite heat exchanger uses longitudinal holes as material holes and transverse holes as heat carrier holes. The fluids in the two holes transfer heat through the partition wall.
3.1.3 Heat exchangers are divided into YKA·I type and YKA·I type according to the characteristics of their transverse holes (see Figure 2). The axis of the transverse hole of the YKA·I type heat exchanger is tangential, and the auxiliary line of the transverse hole of the YKA·I type heat exchanger is radial. 3.2 Series, specifications and installation dimensions
3.2.1 Series specifications and installation dimensions of YKA·「 type heat exchangers are shown in Table 1 and Table 23.2.2 Series specifications and installation dimensions of YKA· type heat exchangers are shown in Table 3 and Table 43.3 Main parts and materials of heat exchangers are shown in Table 53.4 Marking
Approved by the Ministry of Chemical Industry of the People's Republic of China on March 17, 1998 and implemented on October 1, 1998
