Manufacturing a thermoplastic composite tubular structure embedded with a first load fitting comprising the steps of braiding a first plurality of inner layers of thermoplastic composite material around a soluble, expandable mandrel. In one example, the apparatus has a mandrel connectable to a threaded portion of a tubular connection and two face plates bearing cutters for refacing surfaces of the tubular connection. According to one embodiment, systems and methods are provided that analyze various parameters that are derived from the unified data collection system to calculate a QA score for analysis by administrators. The dielectric layer is tunable by varying the stepped layer thicknesses and the geometry of the layer.
