Introduction of red copper tube
Copper pipe, a kind of non-ferrous metal pipe. Is pressed and drawn seamless tube. High low temperature strength. It is often used to manufacture heat transfer equipment (such as condenser, etc.).
Copper pipe features
Copper tube is hard in texture, not easy to corrosion, and high temperature and high pressure resistance, can be used in a variety of environments, can save materials and total cost.
Application of red copper pipe in air conditioning
Used for assembling cryogenic pipeline in oxygen production equipment. Small diameter copper pipe is often used for conveying pressure liquid and used as instrument pressure tube, etc.
Air conditioner copper pipe introduction
Contains no chemical additives, does not burn and release toxic gases to suffocate people. Is conducive to environmental protection, sustainable development of green building materials.
Air conditioning copper tube features
This alloy is particularly suitable for use in the -50°F/+600°F temperature range. Used in pressure vessels, high pressure storage tanks, high pressure pipelines, heat exchangers.
Copper pipe execution standard:
Seamless copper tubes for air conditioning and refrigeration equipment GB/T 17791-2007
Seamless copper pipe for cable
Seamless round copper tube for electrical conductivity GB/T 19850-2005
Oxygen free copper tube for magnetron GB/T 20301-2006
Seamless copper pipe with internal thread GB/T 20928-2007
1. Copper is economic. Because the copper tube is easy to process and connect, so that when it is installed, it can save material and total cost, stability and reliability, and can eliminate maintenance.
2. Copper is lightweight. Copper pipe does not need the thickness of ferrous metal for internal threaded pipe of the same inner diameter. When installed, copper pipe transport costs less, easier to maintain, take up less space.
Copper can change shape. Because copper pipe can bend and deform, it is often made into elbows and joints. The smooth bend allows the copper pipe to bend at any Angle.
Copper is easy to join.
5. Copper is safe. No leakage, no combustion, no toxic gas
