Hot Tapping Machines & Line Stopping Actuators ▼ CHT3000 CHT, LSA Series Tapping Diameters: 3 - 48 inches Maximum Stroke: 43 - 150 inches Maximum Operating Pressure: 1480 - 5000 psi ▼ LSA1420-H LSA-Series Line Stopping Actuators Line Stopping Actuators (LSA) are used in conjunction with the required line stop head and housings to carry out line stops in surface or subsea environments. The range is designed for easy use on pipelines in various materials and differing wall thickness. Their use provides temporary pipeline isolation, temporary or permanent bypass and no costly interruption of service. CHT, HOT TAPPING MACHINES • Working pressure capacity up to 5000 psi (350 bar) • Drive as close to the cut enhances cut efficiency • Auto feed — infinitely variable for differing cut conditions • Constant pressure seal monitoring ports • Internally pressure balanced for higher-pressure applications • Industry standard connection flanges • Compatible with standard industry tooling LSA, LINE STOPPING ACTUATOR • Series of four hydraulic line stop actuators covering a plugging head size range of 4 to 48 inches (102 - 1219 mm) • Maximum working pressure of 1480 psi (102 bar) at 181 ˚F (83 ˚C) • Failsafe mechanical lock prevents control rod movement • Anti-rotation feature to ensure aligned plugging head deployment • Hydraulic control situated at the working end of the cylinder for ease of use • Visible control bar depth control. ▲ CHT3000 hot tapping application for petrochemical pipeline installation.
