High Pressure Piping and Welding Review

Vocabulary flashcards covering high pressure piping concepts and welding procedures based on introductory lecture notes.

Dominant Factor in High Pressure Piping Design

Safety and adherence to the required code.

Steam Separators

Devices used to separate moisture from steam, available in three types: centrifugal, baffle, and cyclone.

Feedwater Heaters

Equipment used to heat boiler feedwater, categorized into two main types: open and closed.

Boiler Horsepower

The equivalent of evaporating $34.5\,\text{pounds}$ of water at $212^\circ\text{F}$ in one hour.

Enthalpy

The total heat content in sensible heat and latent heat.

Saturated Steam

Steam that is in contact with the water from which it is generated.

Back Pressure Valve

A valve used on a feedwater line, on the discharge of a steam turbine, or on the discharge of an ammonia line.

Converter (Heat Exchanger)

A device used for heating fluid media, heating air, heating oil, or heating steam.

Tube Sheet

The plates into which the tubes are rolled in a fire tube boiler.

Minimum Preheat Temperature

The required minimum preheat temperature of $50^\circ\text{F}$ for welding.

Seal Welds

Welds that must entirely cover the exposed threads.

Welding Records

Documentation maintained for welding operations, including WPS, PQR, WPQ, welder stamps, and welding logs or maps.

WPS

Welding Procedure Specification.

PQR

Procedure Qualification Record.

WPQ

Welder Performance Qualification.
