Here We Mainly Introduce Polyurethane Lining In Seamless Steel Pipe. Because Seamless Steel Pipe Is A High Pressure Pipe Directly Rolled By Hot Rolling Without Welding, Polyurethane Lining In Seamless Steel Pipe Is The First Choice When Conveying Wear Medium Under High Pressure.

Of Course, Seamless Steel Pipe Lining Polyurethane Also Has Drawbacks, That Is, Only In The Pipeline Below DN450, Seamless Steel Pipe Is Used, And In The Pipeline Above Dn500, Seamless Welded Steel Pipe Lining Polyurethane Is Usually Used.

In Addition, The Circularity Of The Cross Section Of Seamless Steel Pipe Is Stronger Than Other Types Of Steel Pipe, So It Is Very Easy To Operate When Lining Polyurethane, And It Will Ensure That The Thickness Of The Lining Polyurethane Layer Is Uniform.

At Present, Our Company Undertakes Engineering Projects, Seamless Steel Pipe Lining Polyurethane DN100 DN150 DN200 DN250 DN350 And So On. Seamless Steel Pipes For Polyurethane Lined Pipe Are Generally Small-Caliber Pipes, And Welded Steel Pipes For Large Caliber Pipes.
