Integrated Tee PLR
 
The Integrated Tee Launching PLR is positioned at the supply end of the transfer line and does not require an isolation valve to separate the pig launcher from the transfer line. This type pig launcher is uniquely designed to operate in schedule 10 piping systems where standard isolation valves having schedule 10 internal port diameters are not available. In this type pig launcher, the PLR is combined with a Piggable Tee into a single component and a Pig Stop is used to prevent the pig from being drawn into the product flow during the transfer. The PLR is uniquely equipped with the patented Hiltap LQC quick access safety cap, full pig wiper disc relax chamber, and side entry pig propulsion. The LQC cap allows operators to gain access to pigs in less than 15 seconds and is designed to mechanically lock and remain sealed should the operator attempt to remove the cap when there is pressure in the line. This unique feature allows operators quick and easy access to pigs while simultaneously providing the utmost in operator safety and spill protection. For effective product displacement and line cleaning, all pigging systems require pigs to be compressed tightly in the transfer line. The full pig wiper disc relax chamber allows pigs to easily be inserted and removed from the line without stuffing or use of special devices to tug the pig from the PLR. And lastly, side entry pig propulsion and vent fittings allow the LQC safety cap to be quickly removed by operators without the need for piping disconnections and waiting for busy maintenance personnel to perform this time consuming task. Pressure locking access caps, pig wiper disc relax chambers, and side entry propulsion are unique features of Hiltap manufactured pigging components supplied by Pigging Solutions.
