Common plumbing systems can be divided into a variety of types depending on their use and media. Here are a few of the main types of plumbing systems and their brief descriptions:
1. Water supply pipeline system
function: Delivering clean water from the water source to the various water points.
Materials: Usually use PVC (polyvinyl chloride), PE (polyethylene), copper, stainless steel or galvanized steel pipe, etc.
Fields of application: Homes, commercial buildings, industrial facilities, etc.
2. Drainage pipe system
function: Collect and discharge domestic sewage, stormwater and other wastewater.
Materials: Commonly used are PVC, PP (polypropylene), cast iron, etc.
Fields of application: Houses, public buildings, factories, etc.
3. Gas pipeline system
function: Delivering natural gas or liquefied petroleum gas (LPG) to user terminals.
Materials: Steel pipe or high density polyethylene (HDPE) pipe is generally used.
Fields of application: Home kitchens, water heaters, industrial stoves, etc.
4. Heating ductwork
function: Provides heat to buildings through hot water or steam.
Materials: Commonly used materials include copper pipe, steel pipe and plastic composite pipe.
Fields of application: Residential, commercial buildings, industrial plants, etc.
5. Air conditioning duct system
function: Refrigerant transfer for air conditioning systems.
Materials: Copper pipe or aluminum pipe is usually used.
Fields of application: Central air conditioning system, split air conditioning, etc.
6. Fire-fighting pipe system
function: Provide fire extinguishing water or other extinguishing agents in the event of a fire.
Materials: Steel pipes are mostly used, and sometimes PVC-U (rigid polyvinyl chloride) pipes are also used.
Fields of application: Fire fighting facilities inside and outside various buildings.
7. Industrial pipeline system
function: It is used to transport various fluid media such as steam, water, oil, chemicals, etc. according to specific industry needs.
Materials: Select suitable materials according to media characteristics and process requirements, such as stainless steel, alloy steel, plastic, etc.
Fields of application: Chemical, petroleum, pharmaceutical, food processing and other industries.
8. Electrical conduit system
function: Protects wires and cables from mechanical damage and provides fire isolation.
Materials: Metal pipes (such as galvanized steel pipes), plastic pipes (such as PVC pipes), etc.
Fields of application: Power engineering, telecommunications networks, automation control systems, etc.
9. Medical gas piping system
function: Supply medical gases such as oxygen and nitrogen to hospital wards, operating rooms, etc.
Materials: Copper pipe is often chosen for its good corrosion resistance and safety.
Fields of application: Internal gas supply network of medical institutions.
10. Compressed air duct system
function: Compressed air that provides one of the power sources for plant equipment.
Materials: Aluminum alloy, stainless steel, copper or specific grades of plastic pipe.
Fields of application: Where pneumatic tools are needed in manufacturing industries, auto repair shops, etc.
Each plumbing system has its own specific design standards and technical specifications, ensuring that they can operate safely and effectively in their respective environments. In practical engineering, which type of plumbing system to choose depends on specific use needs, budget constraints, and local regulatory requirements.
