Water pump pipe fittings are important accessories that connect water pumps to pipes. In a pipe system, if there are no accessories, the pipes cannot be connected together, resulting in failure to operate normally. The quality of the pipe connection directly affects the safety and stability of the system. Therefore, it is crucial to choose high-quality pipe fittings.
What are the functions of water pump pipe fittings?
Water pump pipe fittings are the general name of the parts used in pipe systems for connection, control, deflecting, diverting, sealing, and supporting. They play an important role in the fields of water technology, irrigation, and drainage. The main types include:
Connecting pipe : parts used to join pipes, such as flanges, loose joints, pipe bands, clamps, ferrule, throat bands, etc.
Directional fitting : parts for changing the direction of a pipe, such as elbows and bends.
Control fitting : A part, such as a valve, used to regulate or control the flow of fluid.
Diverter fittings : parts for adding pipe branches, such as tee, tee.
Sealing pipe fittings : parts for sealing pipes, such as a gasket, raw material belt, thread hemp, flange blind plate, pipe plug, blind plate, head, and welding plug.
Support pipe fittings : parts for fixing and supporting pipes, such as clasp, tow hook, hanger, bracket, bracket, pipe clamp, etc.
Material selection
1. Cast iron: Cast iron is a commonly used material for water pump pipe fittings, including gray cast iron and ductile iron. Gray cast iron is the most commonly used cast iron, used for the pump body, impeller, pump cover, suspension, etc. of general clean water pumps. Ductile iron is usually regarded as a substitute for cast steel because its mechanical properties are close to steel and it has excellent casting and processing properties. The commonly used types of cast iron Water pump pipe fittings are mainly Ductile Iron Backing rings.
2. Stainless steel: Stainless steel, especially austenitic stainless steel, is often used for water pump bodies and impellers due to its excellent corrosion resistance to avoid polluting water sources and ensure water delivery safety. Austenitic stainless steel is suitable for various working conditions except for a few media such as hydrochloric acid and dilute sulfuric acid, and is a common material for casting water pump fittings.
3. Plastics: Plastic materials such as polyolefins (such as HDPE, polypropylene PP, PVC, etc.), PP-R pipes, AGR pipes, steel-plastic composite pipes, plastic-lined steel pipes, wire mesh skeleton plastic composite pipes and thin-walled stainless steel pipes, etc., these materials have excellent corrosion resistance and temperature resistance, and are suitable for various fluid transmission, especially chemical fluids.
4. Alloy steel : Alloy steel, such as 40Cr, is commonly used as a material for high-strength pump shafts to provide additional strength and corrosion resistance.
5. Non-metallic materials: Non-metallic materials such as polytetrafluoroethylene, fluoro rubber, nitrile rubber, etc. are mainly used for sealing and buffering, have good corrosion resistance and temperature resistance, and are suitable for various working conditions.
The material of water pump pipe fittings is usually the same as that of the pipeline system. According to the connection method, pipe fittings can generally be divided into threaded pipe fittings, welded pipe fittings, flange pipe fittings, and socket fittings. These pipe fittings play a key role in water conservancy facilities, agricultural irrigation systems and other systems that require fluid transportation, ensuring the effective transmission and control of fluids.
