Copper tubes come in various grades, each with specific properties suited to different applications. The most common grades of copper tubes include:
ASTM B88 (Type K, L, M):
Type K: This grade of copper tube has thick walls and is typically used for underground water services and distribution.
Type L: Type L copper tubes have medium thickness walls and are commonly used for residential water supply lines, refrigerant lines, and heating systems.
Type M: Type M copper tubes have thin walls and are suitable for general residential and commercial plumbing applications where pressures are relatively low.
ASTM B280:
ASTM B280 copper tubes are seamless, drawn-copper tubes used for refrigeration and air conditioning systems, as well as in heating applications.
These tubes are available in various tempers, such as annealed (soft) and drawn (hard), to suit different installation requirements.
ASTM B75 (Type K, L):
Type K: Similar to ASTM B88 Type K, these tubes have thick walls and are commonly used for underground water services and distribution.
Type L: Similar to ASTM B88 Type L, Type L tubes have medium thickness walls and are suitable for residential water supply lines and refrigerant lines.
ASTM B88 (Type ACR):
ACR (Air Conditioning and Refrigeration) copper tubes are specially designed for use in air conditioning and refrigeration systems.
These tubes are typically annealed for ease of bending and are available in various sizes to accommodate different system requirements.
ASTM B819:
ASTM B819 copper tubes are seamless copper tubes specifically designed for medical gas systems.
These tubes are cleaned and capped to meet stringent purity requirements for medical gas applications.
Copper-Nickel Alloys:
Copper-nickel tubes, such as CuNi 90/10 (90% copper, 10% nickel) and CuNi 70/30 (70% copper, 30% nickel), offer excellent corrosion resistance and are commonly used in marine and offshore applications, as well as in heat exchangers and condensers in aggressive environments.
These are some of the commonly used grades of copper tubes. The selection of the appropriate grade depends on factors such as application requirements, operating conditions, and regulatory standards. It's important to consult with suppliers or engineers to choose the right grade for your specific application needs.
Classification : Copper Pipes A type of non-ferrous metal pipe, often divided into brass and copper pipes, is pressed and drawn seamless pipe. Copper pipe has good electrical conductivity, thermal conductivity characteristics, electronic products of conductive parts and heat dissipation parts of the main material, and has become a modern contractor in all residential commercial housing water pipeline, heating, cooling pipe installation of the first choice. Copper pipe has strong corrosion resistance and is not easy to oxidize.

Brass tubes, seamless copper tubes
Copper Tubes For Heating Application & Solar Panels : The copper tube we manufacture finds numerous applications in Heating and Solar Panels. For steam-heating systems, especially return lines, the outstanding corrosion resistance and non-rusting characteristics of copper tube assure trouble-free service and maintenance of traps, valves and other devices.
Copper Tubes For Heat Exchangers & Locomotives : We recommend our copper tube for heat exchangers and condensers because copper''s inherent superiority in thermal conductivity, corrosion resistance and strength has made it a preferred primary metal for Heat exchangers(radiators) and condensers since the dawn of cars and trucks.
Copper Tubes (Air Conditioning Systems And Refrigeration Systems) : The Copper tubes that we manufacture are extensively used in Air conditioning systems. The use of copper tube in air-conditioning and refrigeration systems has grown steadily in recent years. This is in large measure due to the inherent properties of the copper metals and their unique abilities to meet the needs of the ACR industry. Stringent new requirements, including demands for increased operating efficiency and the reduction or elimination of harmful emissions, have led to a new appreciation for copper tubes role in product enhancement.
