Polyurethane Lined Pipe Is Based On The Original Carbon Steel Pipe , Using Different Thickness Of Polyurethane Material As The Inner PU Layer To Increase The Wear Resistance Of Carbon Steel Pipe . To Increase The Wear Resistance , Acid Resistance , Alkali Resistance , Antifouling , Radiation Resistance , Hydrolytic Resistance , High Elasticity And Mechanical Impact Resistance Of The Whole Pipeline .
1 . Polyurethane Lined Pipe Is One Of The Main Wear-Resistant Pipes In The World ( Another Kind Of Wear-Resistant Lining Pipe Is Rubber Lined Pipe ) .
2 . When The Conveying Medium Is a Fluid With Large Particles , This Pipeline Is The Best Choice In The Process Of High-Pressure And High-Speed Transportation .
3 . When The Conveying Medium Contains Small Particles ( More Than 80% Of Particles Under 200 Mesh ) , Low Pressure ( Less Than 2.0 Mpa ) And Low Flow Rate ( < 1.8m / s ) , The Polyurethane Inner Liner Is More Economical And Practical With The Soft Medium Conveying Process .
4 . In Addition , Our Company’s Polyurethane Lined Elbow , Polyurethane Lined Reducer , Polyurethane Lined Tee , And Other Polyurethane Lined Spooling Works .
Main Features :
1 . Good Wear Resistance .
Polyurethane Lined Pipe Has Good Elasticity . When Polyurethane Liner Receives The Impact Of Conveying Medium , Polyurethane Is Forced To Extrude Under The Effect Of External Force , The External Force Disappears , Polyurethane Is Recovered , Which Greatly Reduces The Erosion Of Strong Medium On The Inner Wall Of The Pipe Directly , And The Wear Life Is Ten Times Of That Of Steel Pipe .
2 . Prevention Of Pollution .
The Molecular Structure Of Lined Pipe Polyurethane Elastomer Is Symmetrical Inner Liner , Which Is A Non-Polar State Shown Abroad . It Can Not Form Slurry Ca2 , Co32 – , Hco3 , Absorb Oh Plasma , And Form Scale Layer . It Has Smooth Surface , Good Elasticity , And Can Prevent The Adhesion Of Dirt Layer , So It Has a Better Anti Fouling And Anti Scaling Effect .
3 . Low Running Resistance .
The Polyurethane Liner Is Smooth And Transparent , The Absolute Roughness Of The Wall Is 0.082 , Which Can Reduce The Operation Cost .
4 . Good Water Resistance And Aging Resistance .
It Does Not Expand In Water Like Rubber , Which Has An Impact On Performance .
5 . Good Combination .
Polyurethane Lined Pipe Is Closely Combined With Steel Pipe . Polyurethane Lining Is Poured Into Steel Pipe 100% With Unique Process , And Unique Integral Flange Process Does Not Show Peeling , Cavity Or Partial Tear .
6 . Light Weight , Easy To Install .
Because The Main Pipe Is Thin Walled And Light In Weight , The Time Based Connection Method Can Be Adopted : Flange Connection , Flexible Pipe Connection And Welding Connection .
Main Applications :
Polyurethane Lined Pipe Is Widely Used In Power , Coal, Mining , Building Materials , Chemical Industry And Other Industries . It Can Transport Coal Ash , Slag , Ash , Mineral Powder , Aluminum Liquid , Slurry And Other Granular Materials And Slurry Powder Of Corrosive Medium .
