Polyurethane Lined Pipe & PU Lining & Steel Piping Urethane Liner

Polyurethane Lined Pipe Is Our Main Business, Hebei Fengmang Technology Co.,Ltd Is The Earliest Company In China To Produce Poly urethane Lined Pipe. All Polyurethane Raw Materials And Binders Are Produced Independently By Our Company. Whether We Are Products Or Construction, Our Company Has Won The Favor Of Customers All Over The World. The Products Are The First In The Field Of Tailings Discharge. Strong Wear Resistance And Corrosion Resistance Make Our Products Far Ahead Of Other Manufacturers.
From 2 Inch To 38 Inch Diameter Of Lined Polyurethane Pipeline, Our Company Has Rich Production And Construction Experience. The PU Lined Pipe Fittings Are Still Our Main Specialty. For Example: Elbow, Different Diameter Tee, Same Diameter Tee, Concentric Reducer And Eccentric Reducer Etc.
Our Company Sandblasts Steel Skeleton With Unique Advantages To Remove Grease, So As Not To Be Peeled Off After The Completion Of Polyurethane Lining. The Maximum Length Can Reach 12 Meters, But For Ocean Transportation, Standard Pipelines Of 6 Meters Are Generally Produced.

Use And Application
Polyurethane Lined High Wear Resistant Steel Pipe Is One Of The Most Economical Polyurethane Rubber Pipe Fittings. It Offers a Range Of Benefits, And More Expensive Polyurethanes Are Well Resistant To Alkaline And Acidic Chemicals. Polypropylene Lined Pipes Can Be Safely Used At Temperatures Below 90 Degrees f. It Has a Certain Wear Resistance And Becomes Fragile At Lower Temperatures.
Typical Industries And Applications Using Polyurethane Lined Pipes Include Water Treatment, Chemical Processing, Food And Beverage, And Power Generation. For More Information About Detailed Product Specifications And Potential Applications, Please Contact Us Directly.
Outside-Pipe Materials As Below:
Carbon Steel Pipe , Cast Steel Pipe , Forging Steel Pipe , Galvanized Steel Pipe , Ductile Iron Pipe , ERW Welded Steel Pipe , Seamless Steel Pipe , Spiral Steel Pipe
Key Advantages
1, High Wear Resistance And Corrosion Resistance To Ensure That The Discharge Pipeline Is Not Damaged.
2, During Transportation, The Friction Coefficient Of Polyurethane Lining Is Very Low, So The Energy Consumption Is Reduced.
3, The Service Life Of The Pipe PU Lining Can Reach More Than 10 Years Under Strict Standards.
4, In The Wear-Prone Part Of The Pipeline, We Use The Way Of Thickening The Polyurethane Lining To Ensure The Service Time Of The Pipeline.
A105 Seamless Steel Pipe Is Used In Small Diameter Pipeline And ERW Straight Welded Steel Pipe Is Used In Large Diameter Pipeline. In The Selection Of Pipe Material Specifications, Our Company Can Be Customized According To The Requirements Of Different Customers.
Because The Polyurethane Lining Is Formed By Centrifugal Casting, The Inner Lining Of The Pipeline Is Integrated With The Polyurethane Lining Of The Flange Surface, Which Is Not Easy To Fall Off. PU lined Pipe Can Be Used For Medium Transportation From Minus 30 Degrees To 70 Degrees.
Other Relate Production Name: PU lined Pipe , Urethane Lined Pipe , Pipe PU liner / Lining , Pipe Urethane Lining / Liner , Pipe Polyurethane Liner / Lining
Our High Performance Polyurethane Lining Protects Expensive Pumps From Wear And Tear Or Corrosive Material Damage, Greatly Extending Their Service Life, Thereby Saving You Money. In Addition, Polyurethane Lining Is Easy To Replace At The End Of Service Life, Which Greatly Reduces The Closing Time. We Have The Knowledge To Develop Suitable Solutions For You, Whether Your Pumps Are For Water, Sand Or Chemicals.
Key Advantages
Superior Wear Characteristics
Extended Life Of Pump Components
Polyurethane Components Are Easy To Replace, Reducing Downtime
Materials Used For Each Type Of Line Shall Be In Accordance With Jinruida Standard Materials, Which Have Been Damaged Or Have Defects, Shall Not Be Used, Except Minor Surface Marks May Be Dressed Providing The Minimum Wall Thickness Is Not Less Than 87.5 Percent Of Nominal Wall Thickness. Jinruida May Issue Reclaimed Flanges To Be Used By The Fabricator If So Stated In The Purchase Order.
Polyurethane Lining Is The Strongest Among All Soft Wear Resistant Materials. Therefore, Polyurethane Is The Best Choice For Wear-Resistant Lining Pipelines. The Advantages Of Polyurethane Lined Pipes Are Obvious Compared With Those Of Inexpensive Lined Pipes.
The Hardness Range Of Polyurethane Elastomer Is As Low As Shao a10 And As High As Shao d95, Without The Help Of Filler.
Polyurethane Elastomer Still Has Good Elasticity And Elongation Of Rubber Under The Same Hardness As Plastics.
Composition Of Pipe PU Liner
PU Is Called Polyurethane Rubber. It Is An Elastomer With Properties Between Natural Rubber And Plastics. It Is a Synthetic Polymer. At Present, Polyurethane Rubber Used In Pressure Processing Of Metal Sheet Is Mainly Polyester Casting Type. Hydroxyl-Terminated Polyester With Molecular Weight Of About 2000 Was Synthesized By Condensation Of Adipic Acid, Ethylene Glycol And Propylene Glycol.

It Was Further Synthesized With Toluene Diisocyanate (TDI) Into Prepolymer With Lower Molecular Weight Terminal Group Of Isocyano Group. According To The Content Of Isocyano-Terminated Group, It Was Melted And Mixed With MOCA [4.4'-Methylene Bis(2-Chloroaniline)] By Pouring Moulding, And Hardness Was Obtained By Secondary Vulcanization. Polyurethane Rubber Products With Different Heights And Heights.
