Model SR4000 coupon insertion systems are retractable and commonly used in high pressure and high temperature applications. A specially designed packing gland is used to insert or retract a coupon from a pressurised system without a process shutdown. The insertion system is designed to mount onto a 1 inch piping system, but can easily be adapted to fit your specific requirements. The system consists of an insertion rod with a coupon holder, and a packing gland. A safety cable and safety nut are also provided to prevent blowout. Standard packing material in the packing gland is Teflon, however, Grafoil packing can be provided for high temperature applications. Several coupon holders and lengths are available.
