1,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.

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.
