CP-42 Aluminum Constant Pressure Cylinders

The Welker CP-42GA constant pressure sample cylinder has been designed to hold a representative sample at the same condition as in the pipeline. An inert precharge gas holds the piston against the product at slightly above pipeline pressure, thus preventing a phase change to occur. All 7075-T6 aluminum construction allows for high strength as well as light weight.


Please be advised this product has been replaced by the CP-2 found here.
