Hydraulic features lab evaluation
Reducing Flow Friction Test
|
Principle: By calculating the resistance coefficient using recorded water head values under various flow velocity, We can analysis the flow friction difference between MPS coated and blank pipes
|
Inspection: State key lab of hydraulics and mountain &river exploitation & protection of SichuanUniversity
|
Date: 2005.7.28-2005.7.29
|
Results: Reduce flow resistance 10%-20%

Hydraulic features lab evaluation
Reduce Scale and Wax Test1
|
Principle: MPS coating reduce chemical bond action between coating and oil &gas, also MPS coating with smoother surface by compacted cross link molecular structure has lower friction factor and surface energy which keeps various down hole partials from clinging onto coating surface
|
Inspection: Chemical analysis center of SichuanUniversity
|
Solution: 35Mpa, 120℃, Ph5.5, 3.5MPa CO2,100000PPM Cl-,168h
|
Results: Sample coated with MPS is clean
Blank sample is severely corroded with CaCO3 covered
|
Pic 1and Pic 2 are blank sample used by test,Pic3 and Pic4 are MPS coated Sample
