1,Size accuracy


The outside path admission deviation that solder take care of includes the elliptical park a cent , two class, see the table 3, table 4.


 

Outside path in class deviation mm table 3   Outside path in class deviation mm table 4

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.
