The engineered pipe-in-pipe apparatus will allow longer sections of the inner pipe to be used which will reduce the amount of field fabrication and streamline the installation process. The apparatus may be used for both new piping systems as well as the updating or retrofitting of an existing onshore or offshore piping system. | 05-01-2014 |
