What is copper brass copper pipe
Red copper is the copper content of 99.90% or more, copper metal with good characteristics of this high-quality basic metal copper pipe. Brass is a copper zinc alloy tube, the number after the letter H in the grade often represents the median value of its copper content, zinc content is the rest. Different grades of brass pipe, with higher and higher copper content, the overall performance of better quality and elongation, than the red copper pipe has higher strength.
Copper pipe is easy to bend, easy to twist, not easy to crack, not easy to break, frost heaving and impact resistance, hard texture, not easy to corrosion, high temperature resistance, high pressure resistance, can be used in a variety of environments. Now it is generally used as electrical copper tube, refrigeration copper tube, high pressure copper tube, corrosion resistant copper tube, connection copper tube, waterway copper tube, electric heating copper tube, industrial copper tube.
Common copper tube materials
copper tube TP2, T2, TU1
brass tube H62. H63,H65, H68,H70
Copper pipe weight calculation method
(outer diameter - wall thickness)* Wall thickness 0.02796-kg/ m (weight per meter)
Weight calculation method for red copper pipe
[(outer diameter wall thickness)" Wall thickness "0.02670-kg/ m (weight per meter)
Common specifications of copper pipe
DN15(4 in charge), DN20(6 in charge),DN25(1 inch pipe),DN32(1 inch 2 pipe), DN40(1 inch half pipe),DN50(2 inch pipe), DN65(2 inch half pipe), DN80(3 inch pipe),DN 100(4 inch pipe), DN 125(5 inch pipe),DN150(6 inch pipe), DN200(8 inch pipe), DN250(10 inch pipe), etc.
Can be customized according to customer requirements.
Red copper tube and brass tube difference
Copper pipe and advantages
Copper is a relatively pure copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity is better, but the strength, hardness is worse. If do electric wire, the requirement is softer, red copper is a few better. High low temperature strength. It is often used for assembling low-temperature pipelines in heat exchange equipment and oxygen production equipment. Small diameter copper pipe is often used for conveying pressure liquid (such as lubrication system, oil pressure system, etc.) and used as instrument pressure tube, etc.
Brass tube and advantages
Ordinary brass is a kind of copper containing other alloy components, the price is cheaper than copper, conductivity and plasticity is less than copper, but the strength and hardness are higher. Such as connecting parts, the screw on the place to choose common brass.
Copper pipe is the first choice for modern contractors to install water pipes, heating and refrigeration pipes in all residential commercial houses.
because the copper pipe is easy to process and connect, so that when it is installed, it can save material and total cost, has good stability and reliability, and can save maintenance.
Copper is lightweight. For twisted pipe of the same inner diameter, copper pipe does not need the thickness of ferrous metal. 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. Copper is safe. No leakage, no combustion, no toxic gas, corrosion resistance.
copper tube high temperature resistance, can be used in a variety of environments. Compare with this, the shortcoming of a lot of other pipe material is apparent, for instance the multi-purpose galvanized steel pipe in past residence, rust easily, use time is not long can appear tap water hair yellow, current decrescent wait for a problem. Still the intensity that some material falls in high temperature can be reduced rapidly, when be used at hot water tube can produce unsafe hidden trouble, and the melting point of copper is as high as 1083 degrees Celsius, the temperature of hot water system is negligible to copper tube. Archaeologists have found copper water pipes in the Pyramids of Egypt that are 4,500 years old and still working today.
The advantage of copper pipe
It is strong, with the high strength of ordinary metals; At the same time than general metal easy to bend, easy to twist, not easy crack, not easy to break, and have certain anti-freeze bilge and fight impact ability, because this is the construction of the water supply system in the copper conduit once installed, use safe and reliable, even without maintenance and maintenance.
The copper tube is durable, the chemical performance of copper is stable, cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance (the melting point of copper is as high as 1083 degrees Celsius) and other characteristics set in a suit, can be used in different environments for a long time. The service life of copper pipe can be as long as the life of the building, or even longer. For example, the copper plumbing fittings installed in Beijing Union Medical College Hospital in the 1920s still have good performance up to now. Copper pipe is a pipe fully tested by more than 100 years of time and practical experience.
Copper pipe is safe and reliable. It is harder than plastic pipe and has the high strength of general metal (the strength of cold-drawn copper pipe is equivalent to steel pipe with the same wall thickness). It is more flexible than ordinary metal, good toughness and high ductility, with excellent vibration resistance, impact resistance and frost heaving resistance.
Copper pipe sanitation and health, copper water pipe water and antifouling sterilization. Escherichia coli in the water supply does not continue to multiply in the copper pipe; More than 99% of the bacteria in the water will disappear after 5 hours after entering the copper pipe. Water containing copper ions can supplement the body's need for copper, one of the metals that human health needs. Copper tube does not have the chemical composition such as plastic tube modifier, auxiliary agent, additive. The structure of copper tube is extremely dense and impermeable. No matter oil, bacteria, viruses, oxygen and ultraviolet rays and other harmful substances can pass through it and pollute the water. Copper pipes contain no chemical additives and do not burn and release toxic gases that suffocate people. Copper can be recycled, is sustainable development of green building materials.
Copper pipe connection firmness is strong, copper pipe and copper fittings connection, firmness will be greatly enhanced. Although some pipe material part can not use copper qualitative fittings, it still should have a copper fittings in the place of interface with faucet.
Sustainable development. More than 90% of the world's copper can be melted down into recycled copper for further use. Copper neither produces toxic gases or other harmful substances nor other wastes in the process of regeneration, so it is widely used in cold and hot water pipelines used in construction in developed countries and regions in the world. The vast majority of materials can not be completely renewable or partially used after application, and can not reach the performance of raw materials in quantity and quality, consuming a lot of energy and processing costs, and more likely to cause pollution. For example, some plastic pipe, its waste or old pipe can neither be recycled, nor degradable.
