PIPE

OD

remain constant for the same NPS

Higher schedule

thicker wall→smaller ID

Schedule 40

the most common industrial pipe

pressure loss varies

Velocity²

Stainless Steel corrosion resistance

comes from chromium

carbon >0.43%

not weldable

Superheated steam

steam with temperature above saturation temperature

Economizer

uses flue gas heat to preheat feedwater

Daerator

Removes oxygen to prevent corrosion

Steam trap

Removes condensate without losing steam

Steam Accumulator

stores excess steam energy

Flash Steam

steam forms when hot condensate drops in pressure

MAWP

Maximum Allowable working pressure

Water Hammer

Shock due to condensate slugs in pipes

Compressor

is the heart (pumping system) of a refrigeration system which compresses the refrigerant gas going to the condenser.

Condenser

receives the superheated refrigerant and removes the superheat to liquefy the refrigerant (heat rejection)

Expansion Valve (Thermostatic Expansion valve, TXV)

reduces the pressure of liquid refrigerant and regulates the flow towards the evaporator to control the superheating at the outlet of evaporator.

Evaporator

transfers the heat from substance being cooled to a boiling refrigerant.
