Oil and gas extraction equipment generally works in the downhole high-temperature and high-pressure multiphase environment containing a variety of corrosive media such as CO2, H2S, CI, etc., resulting in corrosion perforation and wear failure caused by partial wear frequently occur. These two failure forms often occur simultaneously and promote each other, leading to the shortening of the repair period of the well, increasing oil production costs, and affecting oil production.

The anticorrosive screw pump adopts imported anticorrosive rubber, and the rotor surface adopts laser cladding technology for anticorrosion. The rotor surface increases special material powder to increase hardness, finish and corrosion performance, which can meet the continuous and smooth extraction under certain corrosion well conditions.
