Copper Coil Pipe/Tube is a kind of non-ferrous metal tube. are pressed and drawn seamless tubes. Divided by shape: square tube, round tube, rectangular tube. According to production, it is divided into: small copper coil tubes of about 50 kg and large copper coil tubes of about 100 kg. The grades of commonly used materials for copper coil pipe are: T1, T2, T3, TP1, TP2, TU1, TU2,C10100,C10200; The Copper coil pipe state is: soft state. Copper coil pipe are delivered in rolls. The copper coil pipe/tube is packed with air cushion film and wooden box.
Light weight, good thermal conductivity, high strength at low temperature. It is often used in the manufacture of heat exchange equipment (such as condensers, etc.). Copper coil pipe/tube also used to assemble cryogenic pipelines in oxygen generating equipment. Copper tubes with small diameters are often used to transport pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes used as instruments.
Compared with ordinary plastic pipes, purple copper tubes can be found that the main materials of plastic tubes contain chemical additives such as plasticizer, which are easy to cause escape or hardening and brittle of plastic due to changes in time and temperature. The copper copper tube does not have various modifiers, additives, additives and other chemical components of the plastic tube, and its properties are very stable. Moreover, E. Coli in the water cannot continue to breed in the copper pipe. More than 99% of the bacteria in the water were completely killed after entering the copper pipe for 5 hours. Moreover, the structure of the copper tube is extremely dense and impermeable. Harmful substances such as grease, bacteria, viruses, oxygen and ultraviolet rays cannot pass through it and pollute water quality. In addition, the copper tube does not contain chemical additives, and will not burn and release toxic gases to suffocate people. Moreover, the recycling of copper is beneficial to environmental protection and is a sustainable green building material.
