Remarks:

1) The designation of the pipe shall be based on the nominal diameter and nominal wall thickness (schedule number: Sch). However, for the nominal diameter, either A (mm) or B (in) shall be used, and letter A and B shall be suffixed to the figures of nominal diameter respectively for identification.

2) The value of mass shall be calculated by the following formula and rounded off to 3 significant digits in accordance with JIS Z 8401. However, in the case of exceeding 1000 kg/m, the results shall be rounded off to an integral value of kg/m.

3) When dimensions other than those given in the abovementioned table are required, the dimensions shall be determined as agreed upon between the purchaser and supplier.
