The pressure resistance of copper pipes is several times or even dozens of times that of plastic pipes and aluminum 5083-alloy. It can withstand the highest water pressure in today’s buildings. In a hot water environment, as the service life increases, the pressure-bearing capacity of plastic pipes decreases significantly, while the mechanical properties of copper pipes remain unchanged in all thermal temperature ranges, so their pressure-resistant capacity will not decrease, nor will There will be no aging phenomenon.
The linear coefficient of copper pipes is very small, 1/10 of that of plastic pipes, and will not cause stress fatigue cracking due to excessive thermal expansion and contraction.
The steel pipe has greater strength. Under the inner diameter requirement to ensure effectiveness, the outer diameter is smaller, making it more suitable for concealed burial.
The formula for calculating the theoretical weight of copper tubes: weight per meter = 0.02796 × wall thickness × (outer diameter – wall thickness). The following is the commonly used calculation formula for the weight of cnc machining copper tubes.
Brass tube: weight per meter (kg) = 0.02670*wall thickness*(outer diameter-wall thickness)
Red copper is pure copper: Pure copper is purple-red, also known as red copper. The density of pure copper is 8.96 and the melting point is 1083°C.
The mass of copper tube is calculated as follows:
G=8.96πδ(D-δ)/1000
G: mass kg
δ: Pipe wall thickness mm
D: Pipe diameter mm
