Description
Brass coupling is a type of fitting used to connect two sections of pipes, typically used to extend pipes, change pipe materials, or repair pipes. Its design is simple, but it plays a crucial role in the pipeline system, ensuring that fluids (such as water, gas, or oil) can flow smoothly in the pipeline system.
Quality inspection and control
To ensure the reliability of the coupling, we usually conduct strict quality inspections, mainly including the following:
Dimensional accuracy testing:
Use tools such as vernier calipers and thread gauges to ensure that the thread and inner and outer diameter dimensions meet the standards.
Voltage withstand test:
Conduct pressure testing within the range of 2.0~5.0 MPa, simulate the actual usage environment, and ensure no cracking or leakage.
Corrosion resistance test:
Salt Spray Test: Used to test the corrosion resistance of surface coatings.
DZR Test: Suitable for gas and water supply systems.
Sealing test:
Ensure that the coupling does not leak under high pressure conditions through an Air Tightness Test.
How to choose high-quality brass coupling?
Check the material:
DZR brass (CW602N): corrosion-resistant, suitable for gas pipelines.
CW617N brass: suitable for water supply systems.
Observe machining accuracy:
Whether the threads are smooth and free of burrs, and whether the interfaces are concentric and without deviation.
Check the sealing performance:
Does it have an O-ring seal and support quick plug connections.
Does it comply with relevant standards:
When purchasing, prioritize products certified by ASTM, EN, and ISO.
Summary
Brass couplings, as the core fittings for pipeline connections, are widely used in fields such as water supply, gas, HVAC, industrial fluids, cable conduits, etc. due to their advantages of high strength, corrosion resistance, high temperature resistance, and good sealing. In the future, with the strict implementation of environmental regulations, brass and brass coupling will become mainstream in the market, and intelligent pipeline technology will also promote more efficient and convenient connection methods.
