Pressure maskers and pressure masking systems
Pressure maskers for masking at least one passageway of an article include a body portion that surrounds at least a portion of the article around the at least one passageway, at least one fluid inlet connected to the body portion that provides a conduit for pressurized masking fluid to pass from an exterior of the pressure masker to an interior of the pressure masker, wherein the article is at least partially disposed within the interior of the pressure masker, and at least one seal that seals the body portion at least partially around the article such that the pressurized masking fluid that enters the interior of the pressure masker is at least partially forced through the at least one passageway.
1. A pressure masker for masking at least one passageway of an article, the pressure masker comprising:
a body portion that surrounds at least a portion of the article around a first side of the at least one passageway, wherein the body portion does not surround a second side of the at least one passageway;
at least one fluid inlet connected to the body portion that provides a conduit configured to pass pressurized masking fluid from an exterior of the pressure masker to an interior of the pressure masker, wherein the first side of the at least one passageway of the article is at least partially disposed within the interior of the pressure masker; and,
at least one seal that seals the body portion at least partially around the article such that the pressurized masking fluid that enters the interior of the pressure masker is at least partially forced through the first side of the at least one passageway and exits out the second side of the at least one passageway.
2. The pressure masker of claim 1 further comprising a hinge that transitions the pressure masker between an open position and a sealed position around the article.
3. The pressure masker of claim 2 further comprising a releasable securement device that releasably secures the pressure masker in the sealed position.
4. The pressure masker of claim 1 , wherein the body portion is impermeable such that the pressurized masking fluid cannot pass through the body portion from the interior of the pressure masker to the exterior of the pressure masker.
5. The pressure masker of claim 1 , wherein the fluid inlet comprises the body portion.
6. The pressure masker of claim 1 , wherein the at least one fluid inlet passes through the at least one seal.
7. The pressure masker of claim 1 , wherein the article comprises a turbine component.
8. The pressure masker of claim 7 , wherein the turbine component is a transition piece or a liner.
