Zusammenfassung:A safety valve 10 comprising: a housing having a bore 14, wherein the bore comprises an internal profile; a flow tube residing in the bore and configured to move telescopically within the bore; an annular section 20 between an inner surface of the housing and an outer surface of the flow tube; a valve closure member 18, wherein the flow tube is adapted to shift the valve closure member between a closed position and an open position; and a temporary barrier 32 that adheres to and protects the internal profile by creating a seamless and continuous diameter within the bore, wherein the temporary barrier is configured to prevent fluid flow through the bore from entering the annular section. The temporary barrier may be a coating, such as an adhesive coating, and the temporary barrier may be degradable or dissolvable. The safety valve may also comprise a spring and a piston, wherein the piston can be hydraulically actuated.
