Samplers
Product description
SCX series sampler designed and manufactured with UOP technology is used for non-leakage sampling of middle-and low pressure toxic, combustible and explosive gas and liquid medium in petroleum and chemical engineering piping system. The sampler features real sampling, high accuracy, no leakage liquor and residual gas relief, thus preventing risks to operator by toxic and harmful gas and environment and any dangerous accident caused by combustible and explosive gas during sapling operation. The sampler series fully meets with the requirements of environment protection, fire and explosion prevention of our country.

SCX series samplers have been widely used in petroleum chemical equipment of our country for hydrogen addition to residual oil, heavy oil catalysis and gas separation, which win good evaluation from the customers. SCX series samplers manufactured by our company mainly consist of two types: SCXL on-line sampler and SCXM closed sampler. The main material of samplers is 1cr18Ni9Ti or oCr18Ni9Ti.
1、SCXL on-line sampler
■ Structural features
SCXL on-line sampler mainly consists of emergency valve, driving screw, valve shaft, screw support, handle, trunk piston, outlet tube sealing padding and connecting flange. The trunk piston passes through the valve shaft and flange, which eliminates residual gas (liquor) leakage and blocking case of condensation.
■ Application scope and method
