Zusammenfassung:The modular design allows for the negotiation of bends and tees in the pipe (including that of mitered 90-degree bends). It also allows for the future addition of more modules that will enhance the capabilities of this tool, which is launched and retrieved under live conditions using a specially designed launcher. The launcher, consisting of a 10-foot-long pipe rated at 750 psig, is attached to the pipeline using a TD Williamson off-the-shelf 45-degree fitting.
