The concept which Unisert focused on the proposed amalgamation of three materials, a cementitious structure sandwiched between a plastic inner layer and steel or metal outer layer. The patented design attacked, for the most part, the growing concern for internal corrosion control in oilfield pipelines, which is one of the more involved problems to define and solve due to intrinsic difficulties inaccessibility, distance, and monitoring uncertainty. The design’s great advantage, however, is that the implementation method eliminates short-length joints, a troublesome area for many multi-wall piping systems. Essentially speaking, a pipeline is slid into a pipeline, after which a cement slurry is pumped through predetermined lengths to completely fill the annulus between the inner plastic tube and outer steel case. The major art and science of the procedure involve controlling the flow characteristics and properties of a non-Newtonian fluid, the cement slurry, to assure complete continuity of the stress transfer mechanism. Our patented techniques, based on decades of experience, are the only ones known to render an extremely high rate of success.
