Brass pipe - what is it?
Brass, as is known from the school course, is( in the simplest case) an alloy of copper and zinc. Copper alloying with this metal can be accompanied by the presence of aluminum, iron, nickel, lead, tin and some other additives. Such brasses refer to complex alloys, unlike simple copper-zinc compounds.
The production of pipes is most often carried out by methods of cold deformation( drawing) and pressing. The addition of zinc increases, in comparison with pure copper, the hardness of the resulting alloy. In single-phase brass, due to zinc, fluidity, strength and ductility are higher. With the growth of its quantity in solution, the specified parameters of the final material also change.
The letter "L" marks simple brass. Of these alloys, all types of rolled products are also produced. The best indicators of plasticity, as it is commonly believed, is characterized by grade L68.Accordingly, brass pipe Л68 differs the best plasticity, allowing the greatest number of kinks and deformations.
Brass pipe, thin-walled, thick-walled and others
For the production of brass pipes, alloys of various compositions are used. So, for many specialized products, depending on their purpose, alloys can be used at different stages of the phase composition, determining its further class: foundry or deformable. In this case semi-finished products are often performed for further processing.
thin-walled brass pipe for general use is usually performed by pressing or cold-deforming methods( drawn by cold rolling).Widely used such pipes were found as boiler rooms. And for this use, brass L68 is more preferable, as it is more resistant to corrosion.
In view of the requirements for the transport of materials in liquid or gas form under pressure, a brass pipe thick-walled is used. Such a pipe, taking into account the properties of the initial material, is able to solve numerous features of the application problems. As a rule, the manufacturing method provides the possibility of obtaining a high-quality seamless thick-walled pipe.
As already mentioned, in comparison with pure copper, brass has great strength and corrosion resistance. In addition, virtually all brass( without lead-containing) are easily processed by pressure at different temperatures and are perfectly connected by soldering with soft( low-temperature) and solid( high-temperature) solders.
Such remarkable features are particularly suitable for the conditions in which the brass pipe is manufactured and used. Its feature is in the section( square, oval, rectangular, etc.), determined by the need to use in building or other technologies.
These pipes are also characterized by elasticity, high density. The structures from profile pipes proved their strength and reliability and, despite the high enough cost, are widely used in construction.
Compression fittings for brass pipes or what is needed for installation?
For simple applications in various applications, simple brasses can be alloyed with individual metals or metal compounds, usually in small quantities. So, the use of aluminum is due to the features of operation in an aggressive marine environment, etc.
When connecting to the system, compression fittings for brass pipes are used. Such devices guarantee a hermetic, rigid and mechanically stable attachment. Another advantage of the solder connection method is the lack of special equipment and temperature effects.
In conclusion, it should be noted that the weight of the brass pipe is noticeably smaller than many others. Even comparing with copper, at all equal sizes, this indicator is lower by about five to six percent. As a result, the overall weight of the structure or system is also less.
