Connecting Pipelines: The most basic function of pipe fittings is to connect pipes of different lengths, materials, or specifications into a continuous system using methods such as threads, welding, and socket joints. For example, elbows are used to change the direction of pipes, tees or crosses are used for branch pipe connections, and flanges are used to achieve detachable connections between pipes and equipment or between pipes themselves, secured with bolts.
Controlling Fluid Parameters: By installing valve-type pipe fittings (such as gate valves, ball valves, and globe valves), the flow rate, pressure, or direction of fluids can be precisely adjusted to achieve on/off, throttling, or diversion functions. For example, in chemical production, valves must withstand high temperatures and pressures to ensure the safe transport of media; in building water supply and drainage systems, pressure reducing valves can stabilize water pressure and prevent pipe rupture.
Protecting Pipeline Systems: Pipe fittings such as compensators (expansion joints) can absorb the thermal expansion and contraction of pipes due to temperature changes, preventing stress concentration that could lead to cracking; filters use built-in filters to intercept impurities, extending the lifespan of pipes and equipment; and insulating joints are used to prevent electrochemical corrosion and protect metal pipes. Changing fluid state: Reducers adjust fluid flow rate through diameter change design to avoid excessive local pressure; silencers reduce noise during gas emission through porous structure and are suitable for ventilation systems or boiler flue gas ducts.
