Copper pipe is almost pure copper manufactured to the requirements of astm b 42 - standard specification for seamless copper pipe, standard sizes. It may be manufactured from any of five (5) copper alloys (c10200, c10300, c10800, c12000, c12200) that all conform to the chemical composition requirements of alloys containing a minimum of 99.9% copper (cu) and a maximum of 0.04% phosphorous (p). Available sizes are 1/8" to 12" diameters in regular wall thickness and 1/8" to 10" in extra strong wall thickness. The standard length for copper pipe is 12 feet. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes.
Joints in seamless copper pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration.
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 %.
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.
Seamless brass tube is manufactured to the requirements of astm b 135 - standard specification for seamless brass tube and 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: c22000, c23000, c26000, c27000, c27200, c27400, c28000, c33000, c33200, c37000, or c44300 and these alloys contain copper (cu) concentrations of between 60% and 90% with various percentages of zinc (zn), lead (pb), and tin (sn) permitted, depending on the alloy.
Tubes meeting this standard may be furnished in any of several tempers ranging from light drawn to light annealed. It is the responsibility of the purchaser, when ordering to provide the requirements for alloy (uns#), temper, dimensions (diameter and wall thickness, or distance between parallel surfaces), form (straight lengths or coils), and total length or number of pieces of any particular size.
Copper tube used for air conditioning and refrigeration applications in the field (sometimes called "refer" or "acr" tube) is an almost pure copper material meeting the requirements of astm b 280 - standard specification for seamless copper tube for air conditioning and refrigeration field service. It is 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 %.
B 280 tube is produced in straight lengths or coils in tempers h58 or o60 respectively, although annealed straight
Air conditioning and refrigeration tube (astm b 280) either coiled or straight length is further required to be cleaned and capped prior to shipping.

We hold immense expertise in making available Copper in many forms
including LME registered and non registered cathodes, billets, rods,
cakes, bars, foil, sheet, granules, plates, powder, shot, turnings, wire,
insulated wire, mesh and “evaporation slugs”.
Copper is one of the most important metals. Copper is reddish with a bright metallic
lustre. It is malleable, ductile, and a good conductor of heat and electricity (second
only to silver in electrical conductivity). Its alloys, brass and bronze, are very important.
Monel and gun metals also contain copper. The most important compounds are the
oxide and the sulphate, (blue vitriol

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.
