In a bioinspired approach, we have used (as scale inhibitors) several non-toxic, “green” polyelectrolytes that possess “active” chemical moieties, capable of stabilizing silicic acid, for a prolonged time period. These additives include either neutral or charged polymers that stabilize two soluble forms of “Si”, silicic and disilicic acids.
Revised in 2016! This NACE International standard practice defines the process necessary to design, install, and operate a thermoplastic-lined oilfield pipeline and provides a foundation for proper use of thermoplastic liners in cases where there is no established standard. It is not intended to replace existing national or corporate standards and requirements based on specific local experience. This standard is intended for use by liner installers, owners of lined pipelines and pipelines that might at some point need a liner, liner materials suppliers, and consultants, and engineering firms engaged in the subject field.
