Description
This set of plastic replicas represent miscellaneous specimens, such as an example of boat sampling (trepanning), preparing the transitioning of the external surfaces of two different wall thicknesses together whereas they can be welded, transitioning the inside diameter of a thicker pipe whereas it can be welded to a thinner wall thickness pipe, 1″ O.D. tubing welded together with a resistance flash butt weld process and an example of a good 2.5″ O.D. pipe with a good root pass and face reinforcement.
