3 Types, basic parameters and main dimensions
3.1 The finned thermometer sleeve structure is divided into two types, Type A and Type B. Type A is a finned thermometer sleeve without an overflow measuring head device. Its basic parameters and dimensions are shown in Figure 1, Table 1, Table 2 and Table 4. Type B is a thermometer sleeve with a temperature measuring head device. Its basic parameters and dimensions are shown in Figure 2, Table 2, Table 3, and Table 4.

Continued Table 4
4.1 The steel pipe material used for the glass casing is No. 10 steel, which is accepted according to the provisions of GB8163. 4.2 According to the technical conditions of the glass fin thermometer sleeve, the reference weight is kg
and the nominal pressure is MPa
. 4.3 After the B-type fin thermometer sleeve is assembled, the test pressure after the glass is weighed as specified in Table 1 of GB7994 standard is carried out together with the installed equipment for water pressure test. The test pressure is the nominal pressure of the installed container. The test result should be leak-free. The material of the temperature measuring head sleeve can be provided according to the needs of the user, but it must be resistant to corrosion by the working medium. 4.4
5 Packaging, transportation and storage
5.1 The sugar glass surface should be wrapped with soft objects and firmly fixed in a wooden box. 5.2 No collision is allowed during handling or transportation, and the packaging box shall not be inverted. 5.3 The product should be accompanied by a packing list, a certificate of conformity and an instruction manual. 5.4 The product should be stored indoors and shall not be stacked or inverted in the open air. 131
