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.
