Rotolining Technique

A Seamless Polymer Lining Technique for Carbon Steel Pipes, Fittings and Vessels,  Rotolining is a unique process that has recently seen significant advantages in part complexity and material performance. This technique allows for a seamless polymer lining to be applied to the interior surface of metal structures. The use of high performance thermoplastics in Rotolining assures that this process will continue to grow and be accepted as an industry standard.

Unique Features of Rotolining

One of the unique features of Rotolining is the ability to apply relatively uniform layering of polymer to a very complex interior pipe, fitting and vessel geometry.

Thicker lining can be applied using the rotolining process than by any other technique. The rotational moulding process allows a seamless lining of 2mm to 8mm thick to be applied to the interior surfaces of the carbon steel pipes, fittings and vessels. The heavy lining thickness allows post machining of critical surfaces that would not be possible with a thinner lining applied by other methods. Virtually any type of metal weldment or casting can be rotolined. Line fairly large structures without welds or flared flanges.

Typical structure that would be rotolined are tanks, carbon steel pipes, fittings, and complex welded structures.
