Oil and gas expanders are designed for preliminary removal of gas from the supply pipeline and trapping large mechanical impurities from the oil and gas mixture; they are part of oil treatment plants and installations of preliminary discharge of water .
Characteristics
Part of the equipment
The oil and gas expander is supplied complete with piping, shut-off valves, instrumentation, supports, a service platform and a ladder for climbing to the platform.
The dimensions and volume of the oil and gas expander are determined depending on the desired performance, physical and chemical properties and the gas content of the oil.
The unit is collapsible and is delivered in 100% factory readiness.
Designation
Oil and gas expanders are being developed
and are made
