CMWS-4 PRECISION COMPOSITE SCREEN

The CMWS-4 precision composite screen is a combination of metal mesh screen and a wirewrapped screen. It is composed of 2 layers of metal filter screens, 2 drainage layers, and 1 layer  of wire-wrapped layers. The dual filtration system has excellent sand control performance and  erosion resistance. It is suitable for harsh environments such as thermal production wells, highyield wells and severe corrosion.

FEATURES

◎ Metal mesh filter layer and wire-wrapped filter layer provide dual filter system with good sand  control ability; 

◎ 316L stainless steel wire woven mesh filter structure, high sand control reliability, strong damage  resistance; 

◎ The setting of supporting drainage network can effectively improve the flow characteristics of  fluid, and the overall flow ability is good; 

◎ High permeability, high porosity, large effective flow area; 

◎ Acid and alkali resistance, high temperature resistance and erosion resistance; 

◎ High strength, strong deformation resistance, 40% deformation in diameter direction, sand  control performance remains unchanged; 

◎ High precision sand control, can provide 60μm~300μm filtration rating range of products.
