Product enters into and discharges from the transfer line through a Piggable Tee. The Piggable Tee is equipped with a short tee branch length and tee branch pig bar. The short tee branch length minimizes the branch dead leg and residual product that can fall back into the line after the pig passes underneath. Any residual product remaining in the transfer line will be minimal and is pushed from the main line and out through the Launching PLR vent line to the Demister when the pig is returned from the Receiving PLR to the Launching PLR. The tee branch pig bar assures reliable and smooth passage of the pig under the tee branch without hang-up. With the exception of sanitary piggable tees which have unique sanitary design requirements, the tee branch pig bar is an integrated section of the main line piping. This assures the pig bar has the same surface shape as the pipe and seamless transition of the main line across the tee branch and through the tee. Short tee branch and integrated pig bar design are unique features of Piggable Tees manufactured by Hiltap and supplied by Pigging Solutions.
