Title:
LEAD PIPING DEVICE OF PLANT PIPING
Document Type and Number:
Japanese Patent JPH10122996
Kind Code:
A
Abstract:
To form lead piping for plant piping into a structure capable of readily absorbing excessive relative displacements between foundations.
Lead piping 5 is connected between plant piping 1 and a pressure measuring instrument 4 installed on a foundation 2 other than the foundation of the plant piping 1. A raised part 5a of about 1m is formed in a portion of the lead piping 5. A coiled piping part 5b is formed in the raised part 5a so that it has a gradient of 1/20 or greater. The relative displacements between the foundations are absorbed by the elastic deformation of the coiled piping part 5b.
