Brass Pipe High Strength, Large Hardness, Strong Chemical Corrosion Resistance
The Brass Pipe has lighter weight, good thermal conductivity and high low-temperature strength. Often used in the manufacture of heat exchange equipment (such as condensers, etc.). Also used in oxygen production equipment assembly of Low-temperature pipeline. Small diameter copper tubes are often used for conveying pressurized liquids (such as lubrication systems, hydraulic systems, etc.) and for gauges. Brass Pipes have strong, corrosion-resistant properties.
Mainly has the following several advantages: the copper tube texture is hard, not easy to corrode, and high temperature resistance, high pressure, can be used in a variety of types of copper environment. Compared with the Brass Pipe, many other pipe defects are obvious, such as the use of more galvanized steel pipe in the past, it is very easy to rust, the use of the time is not long will appear running water yellowing, small water and so on. There are also some materials at high temperature of the strength will be rapidly reduced, used in hot water pipes will produce unsafe hidden
Patient。 However, because the melting point of copper is up to 1083 degrees, the temperature effect of the Brass Pipe is basically negligible. Common brass pipes include Brass Pipes for electrical appliances, Brass Pipes for refrigeration, high pressure Brass Pipes, corrosion-resistant Brass Pipes, brass pipes for connections, Brass Pipes for waterways, electric Brass Pipes, and industrial Brass Pipes.
If it is composed of more than two kinds of elements of a variety of alloys called special Brass. Copper alloys consisting of lead, tin, manganese, nickel, iron and silicon. Brass has a strong abrasion resistance. Special brass is also called Special brass, it has high strength, large hardness, strong chemical corrosion resistance. The mechanical properties of the cutting process are also prominent. The seamless copper tube, which is drawn by brass, is of high quality, soft and abrasion resistance. Brass seamless pipe can be used for heat exchangers and condensers, low-temperature pipelines, submarine transport pipe. Making sheet, strip, bar, pipe, casting parts, etc. Copper in 62%~68%, plastic strong, manufacturing pressure-resistant equipment.
Brass rods are divided into common brass and special brass, depending on the type of alloying elements contained in brass. The pressure machined brass is called deformed brass.
What is the method to prevent the stress breakage of copper tube rods during the processing of brass rods?
Copper pipe bar, especially high zinc brass, silicon manganese brass pipe bar in the process of processing, because of uneven deformation, will make the pipe bar produced internal stress, the existence of internal stress will lead to material in the processing, use and storage of deformation and even cracking. The prevention method is to eliminate internal stress annealing in time under recrystallization temperature, especially for those alloy materials with internal stress sensitivity such as high zinc and brass to eliminate internal stress annealing within 24h after rolling or stretching.
