PU Lined Sleeve Is One Polyurethane Sleeve Wrapped In Steel Frame Is Made Of Steel Pipe , That Is To Say It Is Polyurethane Lined Sleeve , Which Is Similar To Short-Section Polyurethane Lined Pipe . The Only Difference Is That The Polyurethane Lining Sleeve Often Has No Flange , But It Is Only Polyurethane Linings Inside The Steel Pipe , Where The Urethane Liner Is Often Thicker And The Wear Resistance Is Very High .

This Kind Of Polyurethane Sleeve Is Not Used To Transport Mud Or Slurry Like a Pipeline , But To Be One Kind Of Polyurethane Protector That Protect a Kind Of Rope From Severe Wear And Tear During The Round Trip . Of Course , The General Situation Can Be Replaced By Polyurethane Pulley . But If You Need To Install a Rope Control Device , You Can Only Use This Sleeve To Control .

Steel Coated PU Sleeves Often Need To Be Installed And Fixed In Some Special Environment , Not Used In Mobile Devices . Even If It Moves , It Moves With The Whole Machine .

To Be Used For Polyurethane Rope Sleeve , The Polyurethane Surface Is Naturally Oiled And Highly Lubricated , Which Saves The Working Pressure Of The Rope And Improves The Working Efficiency .

The Wear Resistance Of Polyurethane Is Very High . When The Rope Rubs Against Polyurethane , The Damage Of Polyurethane Is Very Small .

The Elastic Properties Of Polyurethane Elastomer Liner Are Often Not Highlighted Here , But The Hardness Of Polyurethane Is Relatively High , Generally More Than 95 Shore A .
