Note 1: the end of the thread other than the minimum wall thickness should be consistent with the table corresponding to nominal dimensions and level set.
Note 2:2000 level double screw clamp and caps are not included in this standard.

a.When DN65 ( NPS2 ½) pipe fittings pipe using II series of tubes, pipe end OD should be larger than the size specified in the table, to meet the end flange thickness requirements, the remaining size to conform to the requirements of this standard.
