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

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.
