Abstract: Systems and methods for lining a substrate surface subjectable to erosion are provided. The system includes a stud weldable tile including an erosion resistant plate and a stud configured to be welded to the substrate surface. The stud weldable tile can optionally include a breakaway pin operatively engageable with a stud welding gun. The breakaway pin can be detached from the erosion resistant plate after stud welding the stud weldable tile to the substrate surface. The erosion resistant plate can be made of a metal alloy. Alternatively, the stud weldable tile can include an anchor assembly including a stud and a plurality of anchor arms, and an erosion resistant plate being precast around the plurality of anchor arms, the erosion resistant plate being made for instance of a refractory material. The stud weldable tiles can also be used for repairing a lining previously installed on a substrate surface.

Abstract: A pipe or fitting having a polymer liner and a replaceable component including an outer ring having an outside diameter matching the inside diameter of the pipe or fitting, a polymer liner bonded to the outer ring and having an inside diameter matching the inside diameter of the liner of the pipe or fitting. The replaceable component is disposed in an inlet or outlet of the pipe or fitting so as to form a continuous bore lined with a polymer.
