Copper seamless pipe should not be used as a water pipe
In the end, the copper seamless pipe should not be used as a water pipe, a copper pipe, or a nonferrous metal pipe. It is a pressed and drawn seamless copper tube with high low temperature strength. Commonly used in the manufacture of heat exchange equipment (such as condensers, etc.). It is also used to assemble cryogenic piping in oxygen plants. Copper tubes of small diameter are often used to deliver pressurized liquids (such as lubrication
Systems, oil pressure systems, etc.) and pressure meters used as instruments.
Copper pipes have strong, corrosion-resistant characteristics, and become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.
1. Copper is economical. Because the copper tube is easy to process and connect, it can save the material and total cost, stability and reliability during installation, and can save maintenance.
2, copper is light. For internally threaded tubes of the same inner diameter, the copper tube does not require the thickness of the ferrous metal. When installed, copper tubes are less expensive to transport, easier to maintain, and take up less space.
3, copper can change the shape. Because the copper tube can be bent and deformed, it can often be made into elbows and joints. Smooth bending allows the copper tube to be bent at any angle.
4, copper is easy to connect.
5. Copper is safe. No leakage, no combustion, no toxic gases, no corrosion.
The copper pipe is hard and hard to corrode, and it is resistant to high temperature and high pressure and can be used in a variety of environments. In contrast, the disadvantages of many other pipes are obvious, such as the galvanization that was used in many residential buildings in the past.
Steel pipes are easily corroded. The use of water will not be long and there will be problems such as yellowing of tap water and small water flow. In addition, some materials will rapidly reduce their strength at high temperatures, creating insecurity when used in hot water pipes.
Hidden, while copper has a melting point of up to 1083 degrees Celsius, the temperature of the hot water system is negligible on the copper tube. Archaeologists discovered copper pipes up to 4,500 years ago in the pyramids in Egypt and they can still be used

Steel Structure House refers to the
building which is structured by steel beam and column, its advantages are: 1,
light weight, high strength, the weight of Steel Structure is about 1/2 of
concrete structure. 2. Safety and reliability, good resistance to wind and
earthquake. 3. The steel structure components are made in the factory, reducing
the work load in the field, shortening the construction time, and meeting the
requirements of the industrialization. 4. The steel structure factory is made
of reliable quality, accurate size, convenient installation, and easy to
cooperate with the related parts. 5, steel can be recycled, and the environment
is less polluted when it is built and dismantled.
