Selection and Installation of Arms
People! This standard lists the steel, joint, and cast single-tube lights of seven god structures. The selection of the standard production conditions is determined. Seven types of campfires use the method of welding the bottom screen or bottom plate (forged type) with the base bracket and the single-tube flame according to the column and the pipe bracket to determine the two types of application of the pipe system.
A For pipes with outer diameter D, 38mm, select only one type according to table 2. -42-60mm, select only two types according to table 2 and table 3: When the pipe outer diameter D is 73.-426mm, select only four types according to table 3, table 4, table 6 and table 7. When mixed, pay attention to whether the center mark size is the same, or the support height must be adjusted. A3 For pipes with outer diameter 0=4-60mm, single type, high or low, all single type is used. For pipes with outer diameter 73-426mm, single type is used when the system pressure is PN10mA, and double type is used when PN20mA. The investor can also choose single or double row single pipe according to the specific situation of pipeline layout. When using double row, two single pipes are placed on the base bracket, side by side, and the weld should be extended as far inward as possible from the inner side of the flange plate (cell) to the inner side of the flange plate (cell). The single pipe with an outer diameter of D = 71-426mm (B/T2001.68.35.76) is divided into single row and double row types. Single row is single number and double row is double number. The double row is designed according to the effective value E of the table 7.
A6 single pipe top buried steel plate, it is recommended to use 1-shaped steel welding embedded parts. The length of the embedded steel plate [from 500mm, use the structure of Figure A]: >500mm, use the structure of Figure A2. The length of the embedded steel plate and the thickness of the embedded plate are determined by the designer, Figure AI68-1999

Selection and installation of the arm
People! The single-tube light pipes of steel, welded, and cast structures listed in this standard are selected according to the production conditions. Seven types of campfires use the method of welding the bottom screen or bottom plate (forged type) with the base bracket and the single-tube heat pipe system with two types of columns and pipe brackets.
A The outer diameter of the pipe is D, singing 38mm, and only one type of outer diameter of the pipe is selected according to the table. -42-60mm, there are only two types in Table 2 and Table 3: When the outer diameter of the pipe is 73.-426mm, there are only four types in Table 3, Table 4, Table 6 and Table 7. When mixed, it should be noted whether the center mark size is the same, whether it is necessary to adjust the support height A3. For single pipes with an outer diameter of 0=4-60mm, no matter high or low, single pipe clamps are used. For single pipe clamps with an outer diameter of 73-426mm, regardless of the type, single pipe clamps are used when the system pressure is PN10Ma, and double pipe clamps are used when PN20MPa. The investor can also choose single or double row single pipe according to the specific situation of pipeline layout. When using double row, two single pipes are placed on the base bracket, side by side, and the weld should be extended as far inward as possible from the inner side of the flange plate (cell) to the inner side of the flange plate (cell). The single pipe with an outer diameter of D = 71-426mm (B/T2001.68.35.76) is divided into single row and double row types. Single row is single number and double row is double number. The double row is designed according to the effective value E of the table 7.
