3.1 Filter component classification
3.1.1 Grade
The filter element according to the provisions of GB/T 18853, according to the solid particle size value blocked when the filtration efficiency in the liquid is 98%
Row classification, sintered titanium filter components are divided into 7 grades, see Table 1, sintered nickel and nickel alloy filter components are divided into 6 grades, see Table 2.
Table 1 Grades of sintered titanium filter elements
Grade TG001 TG003 TG006 TG010 TG020 TG035 TG060
Note. T in the grade represents titanium material, G represents filtration, and the last three digits represent the particle size value blocked when the filtration efficiency is 98%.
Table 2 Grades of sintered nickel and nickel alloy filter elements
Grade NG001 NG003 NG006 NG012 NG022 NG035
Note. N in the grade represents nickel and nickel alloy, G represents filtration, and the last three digits represent the particle size of the barrier when the filtration efficiency is 98%.
3.1.2 Model
3.1.2.1
Tubular components are divided into four types according to their shape. A1, A2, A3, and A4. See Figure 1 to Figure 4, where the bottom of the A1 and A3 components […]
