![]() Seamless copper water tube is manufactured in sizes ¼" through 12" nominal. 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 %. Type K is the thickest and type M is the thinnest with type L being of intermediate thickness. Seamless Copper Water TubeĬopper 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. It is usually limited to use in specific manufacturing processes or production line type applications. It is this requirement that forces this tube to be a special order tube and not a standard stocked material. 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. 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 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. 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. There is no specific requirements for identification of B68 tube and thus is not specifically designated as a tube permitted for use in most plumbing or mechanical codes. It is the responsibility of the purchaser, when ordering to provide the requirements for alloy (UNS#), temper, dimensions (diameter and wall thickness), form (straight lengths or coils), and total length or number of pieces of any particular size. This tube is provided in annealed tempers meeting O50 - Light annealed or O60 - Soft annealed in either straight lengths or coils. ASTM B68 tube is suitable for use in refrigeration, fuel oil, gasoline, or oil lines where the interior surface of the tube is essentially free of any scale or dirt and is specifically specified as ASTM B68. It may be manufactured from any one of the following alloys: C10200, C10300, C10800, C12000, or C12200 unless specified otherwise on the original contract or purchase order. Seamless Copper Tube, Bright Annealedīright annealed copper tube is an almost pure copper tube manufactured to the requirements of ASTM B 68 - Standard Specification for Seamless Copper Tube, Bright Annealed. Fittings above 2" diameter are normally threaded, flanged, brazed or in some cases grooved mechanical joint fittings are employed. Fittings in the smaller sizes, normally those below 2" diameter are, screwed cast copper alloy or brazed cup cast copper alloy. Joints in red brass pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration. The standard length for red brass pipe is 12 feet.īrass pipe is moderately resistant to many corrosive solutions and is often utilized for water supply and distribution. Available sizes are 1/8" to 12" diameters in both regular and extra strong wall thickness. It is manufactured from alloy C23000 which is comprised of approximately 85% Copper (Cu) with no greater than 0.05% Lead (Pb) and 0.05% Iron (Fe) and the remainder Zinc (Zn). (Red) Brass pipe is an alloy of copper manufactured to the requirements of ASTM B 43 - Standard Specification for Seamless Red Brass Pipe, Standard Sizes. Joints in seamless copper pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes. ![]() The standard length for copper pipe is 12 feet. Available sizes are 1/8" to 12" diameters in regular wall thickness and 1/8" to 10" in extra strong wall thickness. 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). ![]()
