Hardware Fittings Classification
Hardware fittings are important components in various industrial and construction applications. They are used to connect, support, and protect different elements in a system. This article provides a classification of hardware fittings based on their function and application. One common type is the pipe fitting, which is used to connect pipes sections together. Another type is the valve fitting, which is used to control the flow of fluids through a system. There are also various types of bolt, nut, and washer fittings that are used to fasten and secure elements in place. Finally, there are decorative fittings that are used to enhance the appearance of a surface or object. These fittings play a crucial role in the construction and maintenance of various systems and structures.
Hardware fittings, also known as plumbing fixtures, are essential components in plumbing systems. They are used to connect, control, and regulate the flow of water in plumbing systems. Hardware fittings can be made from a variety of materials, including brass, steel, plastic, and stainless steel. They are available in a wide range of shapes and sizes to suit different plumbing applications.
In general, hardware fittings can be classified into several categories based on their function and purpose. Here is a detailed classification of hardware fittings:
1、Pipe Fittings
Connectors: These fittings are used to join two or more pipes segments together. Common connectors include threaded connectors, coupling connectors, and flange connectors.
Tees: Tees are fittings that have three or more ports, allowing water to branch off in different directions. They are commonly used in irrigation systems, plumbing fixtures, and other applications where water needs to be diverted.
Elbows: Elbows are fittings that change the direction of water flow. They are available in both 90-degree and 45-degree angles.
Reducers: Reducers are fittings that reduce the diameter of a pipe. They are commonly used to transition from larger to smaller pipe sizes.
Caps & Plugs: These fittings are used to close off the end of a pipe or to provide a temporary seal.
2、Faucet & Sink Fittings
Faucets: Faucets are the control devices that regulate water flow and temperature. They are available in a wide range of styles and designs to suit different sinks and basins.
Sink Fittings: Sink fittings include the components that attach the faucet to the sink, such as faucet bases, nuts, and washers.
3、Valves & Controls
Valves: Valves are devices that control the flow of water through a pipeline. Common valves include gate valves, ball valves, and butterfly valves.
Controls: Controls are devices that regulate water temperature, pressure, and flow rate. Common controls include pressure regulators, thermostatic controls, and flow meters.
4、Gaskets & Seals
Gaskets: Gaskets are thin sheets of material that provide a sealing function between two surfaces. They are commonly used in pipe joints, flanges, and valves to prevent water leakage.
Seals: Seals are similar to gaskets but are designed to fit within the body of a fitting or valve to provide a tight seal against water pressure.
5、Other Fittings
Adapters: Adapters are fittings that convert one type of connection to another. For example, adapters may convert threaded connections to slip connections or vice versa.
Expansion Joints: Expansion joints are fittings that allow for the expansion and contraction of pipes sections caused by changes in temperature or pressure.
Air Vent: Air vents are fittings that release air from a plumbing system to prevent airlocks or cavitation problems.
Strainers: Strainers are fittings that remove debris from water before it reaches a specific point in a plumbing system, protecting against clogs and damage to appliances like dishwashers or refrigerators with ice makers.
In conclusion, hardware fittings play a crucial role in plumbing systems, connecting, controlling, and regulating the flow of water to ensure smooth and efficient operation. Proper classification and selection of hardware fittings is essential for effective plumbing design and installation.
