SV Series Sandwich Valves are specialized valves used in hot tapping and plugging operations to connect plugging fittings and tapping adapters. They are engineered for safe, non-stop maintenance on pressurized pipelines carrying flammable, explosive, toxic, or hazardous media—including crude oil, chemicals, LPG, gas, natural gas, as well as municipal water and heating systems.
The SDQ Series Plug Setting Tool is used in the final stage of pipeline plugging operations. It precisely positions the plugging stem within the fitting, compressing the seal against the pipe's inner diameter to achieve a permanent seal. This isolates the pipeline section, allowing for the safe removal of all temporary plugging equipment. Designed for non-stop maintenance on pressurized pipelines, it safely handles flammable, explosive, toxic, or hazardous media—including crude oil, chemicals, LPG, gas, and natural gas—as well as municipal water and heating systems.
SFDQ Series Manual Plugging Drives
The SFDQ Series Plugging Drive serves as the primary equipment for pipeline isolation tasks. It acts as the power source for the plugging head, accurately positioning it inside the pipeline to block flows across various pipe diameters. This equipment is suitable for non-stop maintenance under pressure on pipelines carrying flammable, explosive, toxic, or hazardous media—including crude oil, chemicals, LPG, gas, and natural gas—as well as municipal water and heating systems.
FDQ Series Plugging Heads & Drives
The FDQ Series Plugging Drive is the core equipment for pipeline isolation operations. It serves as the power source for the plugging head, precisely positioning it inside the pipeline to block flows across various pipe diameters. Ideal for non-stop maintenance on pressurized pipelines, it safely handles flammable, explosive, toxic, or hazardous media—including crude oil, chemicals, LPG, gas, and natural gas—as well as municipal water and heating systems.
HT-L0608 / L1014 Low-Pressure Hot Tapping Machines
This equipment is dedicated to the pipeline hole equipment. Mainly used in the pipeline does not stop the transmission medium, does not reduce the pressure, to ensure the normal operation of the pipeline, the pipeline maintenance, repair, add bypass equipment.
HT-0614 / HT-1636 / HT-3656 Hot Tapping Machines
A modular series of hydraulic hot tapping machines designed for pipeline maintenance, repair, and branch connections without interruption. Suitable for a wide range of pipeline diameters and pressures.
