The Smart Self-Healing Visco Elastic Solid Coating

Scenario

The most prevalent time-dependent threat to a pipeline is corrosion. Corrosion can occur underground and above ground substrates in the pipelines serving the oil and gas, utility and water industries. The damage can occur  both externally and internally. Corrosion damage leading to leaks and ruptures increases pipeline operating risks associated with health, safety, the environment, product deliverability. This 'oversight' can result in regulatory actions and litigation against pipeline operators.

One major area that becomes a concern is the pipeline field joint. A field joint is a place where two pipeline sections meet and are welded together. Pipeline joints are unavoidable as the very nature of pipelines is the interconnection nature. Pipelines extend for long distances and in various directions. Therefore, there are bound to many field joints where the pipeline sections are joined and welded together. Herein exists the treat of corrosion arising if field joints are not well covered or insulated. Proper field joint anti-corrosive and trusted liquid coatings such as epoxies, urethanes, heat shrinkable sleeves and sometimes fusion-bonded epoxy are required for the field joints.

Remedy

There are new elastic coating technologies that are able to give longer life by virtue of their fundamental chemical and physical characteristics. Armed with an intrinsic chemical inertness, this allows these films to shield surfaces from chemical attacks of many kinds. And their exceptional hardness provides unprecedented protection against erosion and wear. All of these features also serve as powerful  corrosion resistance barrier to stop corrosion attack.

With its unique visco elastic solid characteristic provide self-healing physical properties, client has no more concern and need not to repair even found a small pinhole coating damage during or after pipeline backfill. This unique self-healing viso elastic solid coating will self cover the pinhole automatically by its own nature.

Situational Context

The proper application of fusion bonds, coatings and wrap healing in the field on a pipeline construction project, either on girth welds or various required repairs as pipe casing, buildings, vaults, storm drains, sewer lines is an essential element to the successful long-term integrity of a pipeline. Hence reliance on a trusted, reliant, durable and coatings must become conformative.
