Pipeline fittings mainly include the following categories:
Connection accessories:
Direct (straight through): used for direct connection between pipelines, keeping the flow direction of the pipeline unchanged. There are two types: same diameter direct and variable diameter direct.
Bend: Used to change the flow direction of pipelines, common angles include 45 ° and 90 °, as well as the same diameter and variable diameter.
Three way connection: used to lead out branch pipes on pipelines, forming three directional pipeline connections, which can be divided into equal diameter tees and reducing tees.
Four way: Similar to a three-way, but with four directional pipe connections.
Flange: used for connecting pipes and equipment, and achieving sealing through bolt fastening.
Union: A detachable pipe connection accessory commonly used in situations that require frequent disassembly or maintenance.
Reducing tee and tee: used to connect three or four water pipes of different diameters.
Special functional accessories:
Valves: Used to control the flow of media in pipelines, such as ball valves, globe valves, etc., can be used to regulate flow, pressure, or achieve the cutoff and conduction of media.
Check valve: used to prevent medium backflow in pipelines and ensure the normal operation of pipeline systems.
Compensator: Used to absorb the displacement and deformation of pipelines caused by temperature changes, pressure fluctuations, and other factors, ensuring the stability and safety of the pipeline system.
Filter: Used to filter impurities and particles in pipelines, protecting pipeline systems and equipment from damage.
Expansion joint: used to compensate for axial displacement of pipelines caused by temperature changes, foundation settlement, and other factors, ensuring the flexibility and adaptability of the pipeline system.
Sealing and fixing accessories:
Gaskets, raw tape, and hemp thread: used to ensure the sealing of pipeline connections and prevent medium leakage.
Clamping rings, towing hooks, lifting rings, brackets, brackets, and pipe clamps: used for fixing and supporting pipelines to ensure the stability and safety of the pipeline system.
Other accessories:
Expansion joint, flexible joint, pressure resistant hose: used to absorb pipeline vibration and displacement, protect equipment and pipelines.
Hydrophobes, instruments in pipelines (such as orifice plates), and separators: used to measure and control flow and pressure in pipelines.
The selection of these accessories should be comprehensively considered based on factors such as the type, purpose, connection method, and working environment of the pipeline to ensure smooth connection, sealing, and functionality of the pipeline system.
