4.3.1.4.2. Documentation PipeCoatingSpec¶
PipeCoatingSpec (PV) stands for specification for pipe coating.
It gathers the parameters necessary to specify one type of coating. It is not related to the properties of each coated tube (for this one, refer to CoatedPipe (FV)).
For example, a project needs some 10in linepipe to build a production flowline, and two thickness of coating are required along the line (eg to cope with varying insulation requirements). Then 2 PipeCoatingSpec (PV) instances will have to be specified, one for each thickness.
Once the tubes have to be identified individually, typically during manufacturing, each tube will have its own CoatedPipe (FV) object to describe its properties. The CoatedPipe (FV) objects will refer to the PipeCoatingSpec (PV) they have been manufactured against.

4.3.1.4.5.2. Documentation CoatingLayerSpec¶
CoatingLayerSpec stands for specification of coating layer.
The various CoatingLayerSpec relevant for one coating spec are reported as an Nested Object into PipeCoatingSpec (PV).
A coating is typically made in one or more layers. For example, a 3-layer polypropylene coating is made of one layer of fusion bonded epoxy (FBE), one layer of adhesive and one layer of polypropylene. Each layer will have its dedicated requirement: in PDEF, those layer specific requirements are bundled in a CoatingLayerSpec object, Nested in PipeCoatingSpec (PV) under the coating_layer_spec member.
CoatingLayerSpec is an Nested Object. Therefore, the order in which it is provided in the JSON array is explicitly the order of physical application for the layer. The first CoatingLayerSpec in the array corresponds to the first layer to be applied on top of the bare steel, and so on.
