Hard Drawn Copper Tube
Hard Drawn Copper Tube is the general-purpose copper tube for above ground services. Its ease of manipulation in half-hard condition and relatively light weight, combined with its ability to withstand high internal pressure, makes it the ideal product for most hot and cold water, central heating and gas services installations.
S. K. Metal is one of the leading and renowned manufacturer and exporter of Hard Drawn Copper Tube with a complete range of outer diameter and wall thickness combinations, engineered to exact specifications to meet the highest standards of performance as required by the refrigeration and air conditioning industry. In S. K. Metal copper tubes are available in a variety of tempers to suit the intended applications. It is supply to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. The Copper Heat Exchanger tubes are generally supplied in straight length in even annealed half hard temper. We manufacture Hard Drawn Copper Tube which are compatible to transfer heat in a wide variety of operating conditions and to resist corrosion for the longest period of time possible under the harshest operating conditions.
Our Hard Drawn Copper Tube is used in general engineering purpose mainly because of its thermal conductivity, electrical conductivity, malleability, strength and corrosion resistance. Our manufacturing range of copper tubes possesses roundness, straightness, uniformity of the wall thickness, smooth inner and outer surface to make it the ideal choice for general engineering applications.
S. K. Metal manufacture specially cleaned and degreased Hard Drawn Copper Tube suitable for use in medical and industrial gas applications. These tubes are with ASTM B 819 and are rigorously tested to make sure they are suitable for the exacting requirements of critical medical and gas application industry. S. K. Metal manufacture Hard Drawn copper tubes for residential and commercial plumbing in full accordance with appropriate product standards including BS 2871 Part I, ASTM B 88 and stringent European Standards BS EN 1057:1996. We provide a complete range of sizes and types, engineered to exact specifications to meet the highest standards of performance.
Hard Drawn Copper Tube had been used in the electrical industry for many years because it offers excellent electrical conductivity. Copper is also used as lightening arrester in the electrical transformers. It is very efficient leading to high current densities. These tubes are available in a wide range of outer diameter, wall thickness and temper conditions depending upon the requirement to suit the intended applications.
To meet the ever-increasing demand of Hard Drawn Copper Tubes for the emerging market of solar water heating systems Tube Tech produces Seamless Drawn Copper Tubes in half hard temper and a variety of outer diameter and wall thickness combinations. These tubes are supplied in straight length, cut to the specific sizes to avoid wastage. Tube Tech offers its customers an ultra-clean surface copper tube suitable for all solar thermal absorbers where good welding properties and quality is paramount and hence it is the recommended choice, especially when using ultrasonic or laser welding technology. Our products ensure reduced welding time and increased efficiency of your manufacturing process while saving time and money due to fewer cleaning processes. S K Metal is a leading Manufacturer, Importer and Stockists of Copper Pipe fittings and Copper Tubes for NIBCOP FITTINGS PVT LTD.
