Seamless copper tube manufactured to the astm b 75 - standard specification for seamless copper tube may be either round, square, or rectangular and is suitable for general engineering applications. It may be manufactured from any one of the following alloys: c10100, c10200, c10300, c10800, c12000, or c12200 unless specified otherwise on the original contract or purchase order.
Tubes meeting this standard may be furnished in any of several tempers (h55, h58, h80, o60, or o50) ranging from light drawn (usually limited to round tubes) to light annealed. It is the responsibility of the purchaser, when ordering, to provide the requirements for alloy (uns#), temper, dimensions (diameter, wall thickness, or distance between parallel surfaces), form (straight lengths or coils), and total length or number of pieces of any particular size. It is this requirement that forces this tube to be a special order tube and not a standard stocked material.
It is usually limited to use in specific manufacturing processes or production line type applications.

Copper water tube is a seamless, almost pure copper material manufactured to the requirements of astm b 88 - standard specification for seamless copper water tube, of three basic wall thickness dimensions designated as types k, l, and m. Type k is the thickest and type m is the thinnest with type l being of intermediate thickness. All three types of tube are manufactured from copper alloy c12200 having a chemical composition of a minimum of 99.9% copper (cu) and silver (ag) combined and a maximum allowable range of phosphorous (p) of 0.015 % - 0.040 %.

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.

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.
