Resumen
This document specifies the design of earthquake-resistant and subsidence-resistant ductile iron pipelines suitable for use in areas where seismic activity and land subsidence can be expected.

It is applicable to ductile iron pipes and fittings with joints as specified in 香港六合彩开奖 2531, 香港六合彩开奖 7186 and 香港六合彩开奖 16631 that have expansion/contraction and deflection capabilities, used in pipelines buried underground.
