Secondary is polyurethane foam to provide highly efficient insulation and support carrier pipe along entire length. Insulation in the coupling is refractory composite. 3) CARRIER PIPE: Carbon steel with metalized ends to convey saturated steam. 4) PUSH JOINT COUPLING: Casing; heavy wall FRP pipe to stabilize coupling during expansion and protect the lock block and coupling area from earth loads. Lock Block; reinforced refractory composite to lock bronze coupling into casing and provide insulation to the coupling. Bronze Coupling; machined bronze casting to join two sections of carrier pipe 5) SEALS: End Seal; high temperature elastomer at each end of the pipe lengths to protect insulation from ground water infiltration. Primary Seal; teflon V-Ring supported by stainless steel to provide seal between carrier pipe and bronze coupling. Secondary Seal; high temperature elastomer O-Ring on the bronze coupling to align pipe and provide a back-up pressure seal. External Seal; 30 mil H.T. Tape applied circumferentially around the pipe and coupling casing joint as an additional seal where ground water is severe. Not shown.
