PP-0701-E-004-P, PP-0701-E-004-P

 Alberta registered piping system. The same number has been issued to one vendor working on different skids.

Piping registration is usually limited to one address of installation. Mobile and repeat builds of identical piping systems represent a challenge.  Some jurisdictions will classify the piping system as an oversize fitting to allow repeat builds.  Alberta has implemented mobile registration (Mobile Pressure Piping).
