摘要:
A piping system employs a friction layer of windings, beads or pellets placed between insulation layers and/or on the outermost layer, that being the insulation layer if no jacket is employed or the jacket if it is employed. The windings, beads or pellets are wrapped or applied while the layer is uncured or warm so as to embed themselves into the surface and create a uneven, bumpy or undulating surface. The resulting product increases friction both internally and externally to better restrain or inhibit pipe movement in underground, marine, or subsea applications or provide restraint to the surrounding environment (earth, concrete, etc.).
