Abstract
A seal section for use in a downhole submersible pumping system includes a housing and a seal bag located within the housing. The seal bag includes a substrate having a plurality of substrate surfaces and a metal coating layer on at least one of the plurality of substrate surfaces. The substrate can optionally be configured as a cylindrical form that includes an interior surface and an exterior surface. In particularly preferred embodiments, the substrate is seamless and fabricated from an extruded fluoropolymer. The metal coating layer preferably comprises a metal selected from the group consisting of titanium, stainless steel, nickel, chrome, silver and gold. The metalized seal bag exhibits increased durability and decreased permeability to liquids and gases at elevated temperatures.
