 Here are the common components of an HVAC (Heating, Ventilation, and Air Conditioning) system: Heating Components: 1. Furnace (gas, oil, electric) 2. Boiler (hot water, steam) 3. Heat Pump (air-source, ground-source) 4. Radiant Floor Heating 5. Heat Exchanger (coils, tubes) Cooling Components: 1. Compressor 2. Condenser Coils 3. Evaporator Coils 4. Expansion Valve 5. Refrigerant Ventilation Components: 1. Fans (supply, exhaust, return) 2. Vents (intake, exhaust, transfer) 3. Ductwork (supply, return, exhaust) 4. Air Filters (particulate, gas, odor) 5. Controls (thermostats, humidistats, sensors) Air Handling Components: 1. Air Handler Unit (AHU) 2. Fan Coil Unit (FCU) 3. Blowers 4. Coils (heating, cooling) 5. Plenums Control Components: 1. Thermostats 2. Humidistats 3. Sensors (temperature, humidity, pressure) 4. Controllers (PID, PLC) 5. Valves (control, isolation) Other Components: 1. Pumps (circulating, condensate) 2. Motors (fan, compressor) 3. Drives (variable speed) 4. Insul...

 What is Flange? What are the Types of Flanges Used in Piping System ? Flanges are essential components in piping systems, used to connect pipes, valves, pumps, and other equipment. They allow for easy assembly and disassembly, inspection, and maintenance. Here are the common types of flanges used: 1. Weld Neck Flange - Application: High-pressure, high-temperature environments. - Features: Long tapered hub, welded to the pipe.   2. Slip-On Flange - Application: Low-pressure applications. - Features: Slides over the pipe, welded on both the inside and outside. 3. Socket Weld Flange - Application: Small-diameter, high-pressure pipes. - Features: Socket inside the flange, pipe inserted and welded.  4. Blind Flange - Application: Closing the end of a piping system. - Features: No bore, used to block off a pipeline or valve. 5. Threaded Flange - Application: Low-pressure, low-temperature systems. - Features: Internal threads, screwed onto the pipe. 6 . Lap Joint Flange - Appli...
