Titanium Tube and Shell Heat Exchanger
Water Cooling Evaporator
Copper tube, a non-ferrous metal tube. Is pressed and drawn seamless pipe.
Low temperature strength. Commonly used in the manufacture of heat transfer equipment (such as
condenser, etc.). Also used in oxygen production equipment in the assembly of low temperature piping.
Small diameter brass is often used to transport pressure of the liquid (such as lubrication systems,
hydraulic systems, etc.) and used as a gauge pressure gauge and so on.
Brass with strong, corrosion-resistant features, and become a modern contractor in all residential
commercial housing water pipe, heating, cooling pipe installation of choice.
1, copper is economical. As the copper pipe is easy to process and connect, so that it can be installed in
the material and the total cost, stability and reliability
2, copper is light. For brass pipes with the same inner diameter,
the brass does not require the thickness
of the ferrous metal. When installed, brass delivery costs are smaller, easier to maintain, and less space.
3, copper can change the shape. Because the brass can be bent, deformed, it can often be made of
elbows and joints, smooth bending allows the brass to bend at any angle.
4, copper is easy to connect.
5, copper is safe. No leakage, no combustion, no toxic gases, corrosion resistance.
Brass texture hard, easy to corrosion, and high temperature, high pressure, can be used in a variety of
environments. In contrast, many other pipe shortcomings are obvious, such as the past, the use of
residential galvanized steel pipe, easy to rust, the use of time will not appear tap water yellow, water flow
and other issues. And some materials in the high temperature strength will be rapidly reduced for hot
water pipes will produce insecurity, and copper melting point of up to 1083 degrees Celsius, hot water
system temperature of the brass is negligible. Archaeologists in the Egyptian pyramids found 4500 years
ago, the copper pipe, so far can use.
