A 7 mm copper tube is often categorised based on construction or forms. Copper tube can also be segmented into types based on its usages.
Seamless Copper Tubes
A seamless copper tube is manufactured by extrusion or rotary piercing, among other processes, without a weld line at the copper tube's inner/outer diameter. These tubes enjoy high pressure and temperature resistance. They are also more reliable in strength. The 7 mm seamless copper tube is mainly used in critical aerospace and automotive applications, where a weld line could cause structural failure.
Welded Copper Tubes
Welded copper pipes feature copper sheets with edges that are bonded either by welding or application of pressure. These are mostly used where lower tensile strength and resistance to pressure are tolerable. 7mm copper pipe for air conditioning or refrigeration systems, heating and cooling coils, or general plumbing systems where normal pressure would work are good examples.
Rough Copper Tubes
This is the thin-walled copper tube variety. They are used to manufacture high-quality plain copper sheets and mainly feature a roughened surface and noticeably thinner walls than other tubes. 7 mm copper tubing's ideal purpose is operation research for temperature sensitive components. They can also be used in machinery for manufacturing parts. Rough copper tubes are also helpful as heat exchangers in HVAC systems.
Rigid Copper Tubes
Rigid copper tubes are stiff and only bendable to a certain extent. They are durable and strong, making them ideal for structures. They are often used in the construction of frameworks, for instance, that of heat exchangers and condensers.
Flexible Copper Tubes
These are copper tubes that can bend easily. They are useful when the area where they are going to be installed is limited, or a lot of bends are required. Flexible copper elements are ideal for refrigeration. They make piping systems where occasional adjustments are required easy. They are also used in architectural and medical equipment designs.
Copper is highly resistant to corrosion. This property is attributed to the formation of a protective patina layer on copper's surface. The patina helps in protecting copper metal underneath from oxidation, particularly in moist or corrosive environments. Thus, a 7 mm copper pipe can be used outdoors or in plumbing systems and will not easily corrode.
Copper is among the most thermally conductive metals after silver. Its conductivity enables it to transfer heat or cold quickly and evenly. Copper pipes are commonly used in HVAC systems for heat exchangers, cooling lines, and condensers. They are also used in the manufacture of cookware and other heat transfer devices.
Copper has great electrical conductivity. As a result, it is the metal of choice for electrical wiring. A 7mm copper tube is used in electrical system components, for instance, sensors and solenoids. Furthermore, its thickness makes it ideal in the automotive, aerospace, and renewable energy fields for wiring and grounding.
Copper's malleability makes it easy to work even in its hardest states. Copper can be impact stretched into sheets, drawn into wires, and rolled into plates. It can also be cut, shaped, and machined into tools. Copper's machinability makes it highly useful in many industrial applications. These applications range from component manufacture to architectural design.
Copper is highly recyclable without any quality degradation. Recycling also significantly reduces copper's environmental impact, which is a good thing since copper mining is unsustainable. Moreover, recycled copper retains its quality and properties. Copper can be repeatedly recycled and re-used in plumbing and electrical systems, architecture, automotive, and renewable energy systems.
7 mm copper pipes are used for carrying water and other liquids. The pipes are corrosion-resistant, hence ideal for carrying water, which can be corrosive to other metals. Copper pipes have also been used since ancient times. Therefore, installers trust copper's strength and durability. Copper pipes are easily cut to the required length and bent for installation in tight spaces or around obstacles.
7 mm copper pipes are mostly used in AC and refrigeration systems. They form the copper lines carrying refrigerant gas or liquid. Copper is thermally conductive and enables quick and even heat exchange. Its corrosion resistance enables the pipes to endure the harsh chemicals often inside refrigerants. Copper tubing can be easily bent without cracking. This property is ideal when running refrigerant lines with many adjustments in direction.
In industries, copper tubes transfer fluids and gases in machinery and equipment. Their corrosion resistance and durability allow the tubes to carry various industrial fluids with chemical properties, including corrosive ones. Copper's thermal conductivity makes it ideal for transferring heat within components such as heat exchangers and coolers, making it suitable for many industrial applications that require efficient heat transfer.
The aerospace industry manufacturers components that use 7 mm copper tubes. Copper's high strength-to-weight ratio makes it highly suitable. Copper tubes have high electrical conductivity. Therefore, they are used for wiring or other electronic components. Most importantly, copper tubing can be formed into complex shapes for aeronautical components while maintaining its structural integrity under extreme conditions.
7 mm copper pipes find uses in medical equipment such as copper pipes for blood pressure monitors, surgical instruments, and diagnostic devices like X-ray machines. Copper's inherent antimicrobial properties enable it to kill or hinder the growth of disease-causing microorganisms on its surface. It makes copper a highly hygienic and easy-to-sanitize material in the manufacture of medical devices used in healthcare to prevent infections.
Copper pipes form parts of brass musical instruments like trumpets, trombones, and tubas. Brass, an alloy of copper and zinc, produces a warm, rich tone that is highly valued in these instruments' sound quality. Copper's malleability enables it to be shaped into complex designs, producing a high-quality, resonant sound. Copper parts are also durable and offer great tonal stability, making them a staple in professional and student ensembles.
The metals used to make the copper tube determine its quality. Choose a copper tube made from high-quality metals such as 110 copper or C122. Also, ensure the copper has undergone the proper treatment processes to improve its corrosion resistance and tensile strength.
The rolling process used greatly affects the copper's properties. Hot-rolled copper is great for large structures that require a copper sheet. Cold-rolled copper is ideal for fine and detailed crafts where the sheet's tensile strength is enhanced.
Choose to source the copper tube from a supplier with positive reviews. The supplier should be one that has been in the business for many years. They should sell copper tubes that users have attested work well for their intended uses. Moreover, buying from such a supplier gives users room for bulk purchases. Buying in bulk often comes with a discount.
Make sure the 7 mm copper tube complies with International Organisation for Standardization (ISO) and American Society for Testing and Materials (ASTM) standards. A tube that meets these standards is often of high quality and safety. Subtly asking for proof can save one from copper tubes that may be non-compliant and hazardous.
Apart from plumbing, a 7-millimetre copper tube is used in AC and refrigeration systems, industrial machinery, aerospace, medical equipment, and musical instruments.
Some advantages include strong and durable, easy to bend and cut, corrosion-resistant, non-toxic, highly conductive, and versatile.
Focus on elements like metals, rolling processes, compliance with ISO and ASTM standards, and sourcing from a reputable supplier.
The copper tube's wall thickness typically ranges from 0.6 millimetres to 1.2 millimetres. The most ideal is the 0.8 mm wall thickness because it achieves an optimal balance between flexibility and structural integrity.
