Size accuracy
The outside path admission deviation that solder take care of includes the elliptical park a cent Ⅰ , Ⅱ two class, see the table 3, table 4.
| ⅠOutside path in class deviation mm table 3 | | Outside path inⅡ class deviation mm table 4 |
| Outside path | Admission deviation | | <25 | ±0.10 | | ≥25~38.1 | ±0.15 | | >38.1~50 | ±0.20 | | ≥50~63.5 | 0.25 | | >63.5~76 | ±0.30 | | ≥76~102 | ±0.40 | | | | Outside path | Admission deviation | | ≤10 | ±0.15 | | >10~32 | ±0.20 | | >32~50 | ±0.30 | | >50 | ±0.8% | | | | | | | |
The thick the deviation of admission( do not include the weld sew) in wall of the weld tube is for ruling the wall thick 10% of ±, but minimum admission deviation is the 0.02 mms of ±.
The weld takes care of of settle Chinese foot length as 3 ms~9 ms, general settle the Chinese foot with the 6 ms.
The weld takes care of of settle the Chinese foot length in usually length, its the deviation of admission is the 5 mms of ±.
Adopt partial the degree of flinch in a the tube of weldfor keeping the Chinese foot measurement should not very in 2.0 mms.
