2 Inch 90 Degree Aluminum Elbow Fitting

A new choice for lightweight anti-corrosion: The Characteristics of Aluminum Elbows and the Way to System Compatibility
In the turning solutions of pipeline systems, aluminum elbows occupy an important position due to their unique material advantages. As a core accessory for connecting two aluminum tubes, it can flexibly achieve horizontal or vertical turning of the pipes, covering various angles such as 90 degrees, 45 degrees, and 180 degrees. Its specifications are precisely customized based on the pipe diameter and wall thickness, and it is widely applicable to various industrial and civil scenarios. With the four core advantages of corrosion resistance, lightweight, economy and good processability, aluminum elbows, in combination with accessories such as Rubber Expansion Joint and Bellow Expansion Joint, inject dual guarantees of high efficiency and reliability into the pipeline system. ​
The corrosion resistance of aluminum elbows is unparalleled. They can resist the erosion of corrosive media such as acids and alkalis, do not rust, do not breed bacteria, and have no risk of electrochemical corrosion. This feature makes it shine in water treatment and the transportation systems of light corrosive media in the chemical industry. In such scenarios, aluminium elbows can be matched with aluminium interfaces of Flexible Metal Hose. The flexible turning of the Metal Hose complements the fixed turning of the elbow. Meanwhile, a sealed connection is achieved through Flange Adaptor to avoid contact of different materials affecting the anti-corrosion effect. If there is a risk of medium backflow in the system, a Duckbill Check Valve can be installed downstream of the aluminum elbow. The one-way flow function of the check Valve combined with the corrosion resistance of the elbow can effectively prevent the damage to the pipeline caused by the backflow of corrosive media. ​
Lightweighting is another major highlight of aluminum elbows. The low density of aluminum makes its weight much lower than that of elbows made of carbon steel, stainless steel and other materials, greatly reducing the difficulty of installation and transportation. In weight-sensitive scenarios such as building water supply and drainage, air conditioning and HVAC, the combination of aluminium elbows and Rubber Expansion Joint is particularly suitable - the elastic compensation ability of rubber absorbs pipeline vibration, and the lightweight characteristic of aluminium elbows reduces the load-bearing pressure of the support. The two are connected through threads or flanges to form an efficient steering unit. For temporary pipelines that require frequent disassembly and assembly, aluminum elbows can be used in conjunction with Dismantling joints (detachable joints). The lightweight material makes disassembly and reinstallation more effortless, significantly enhancing the efficiency of system maintenance. ​
In terms of economy, aluminum elbows have a significant cost-benefit advantage. Their relatively low price makes them an ideal choice for budget-sensitive projects. In common industrial cooling water pipelines or low-pressure compressed air systems, aluminum elbows can replace some carbon steel elbows and be connected with Flange adaptors to form an economical and practical steering solution. If there is a slight displacement requirement in the system, the combination of Rubber Expansion Joint can achieve flexible compensation at a lower cost. There is no need to invest in the expensive Bellow Expansion Joint, and the project cost can be controlled while meeting the basic working conditions. The good processability enables aluminium elbows to be customized in terms of angles and interfaces according to requirements. For example, in equipment pipelines with limited space, aluminium elbows with special angles can be customized to cooperate with Flexible Metal hoses. The flexibility of the Metal Hose compensates for the limitation of fixed elbow angles, and the flexibility of system layout is enhanced through customized adaptation. ​
During the selection stage, aluminum elbows need to comprehensively consider the working condition parameters and the coordination of accessories. For the material of the pipe, aluminum elbows should be preferentially connected to aluminum pipes or adapted to pipes of the same light metal through Flange adaptors to avoid corrosion caused by contact of different metals. In terms of pressure rating, aluminium elbows are suitable for medium and low-pressure systems. When combined with Rubber Expansion Joint, the safety in low-pressure scenarios can be further enhanced, while in high-pressure working conditions, the combination of Bellow Expansion Joint and alloy steel elbows needs to be handled. The characteristics of the medium determine the matching of accessories. In pipelines with light corrosive media, the combination of aluminium elbows and Flexible Metal Hose is reliable enough. If the operating temperature is within the tolerance range of aluminium, it can be directly connected to the pipeline. In high-temperature scenarios, the heat resistance limit of aluminium needs to be evaluated. If necessary, Bellow Expansion Joint should be used to compensate for the temperature displacement. ​
From installation to operation, the advantages of aluminum elbows run through the entire process. The aluminum elbow with Flange connection precisely aligns the interface through the Flange Adaptor and evenly tightens the bolts to achieve sealing. The aluminium elbow with threaded connection can be directly connected to the Threaded Rubber Expansion Joint. It is convenient to install, lightweight and reduces the construction intensity. During maintenance, the aluminum elbow can be quickly disassembled for inspection with the help of Dismantling Joint. Combined with the regular inspection and the coordinated protection of Duckbill Check Valve, the system life can be significantly extended. ​
Aluminum elbows, with their corrosion-resistant, lightweight and economical features, have blazed a unique trail in the field of pipeline steering. It complements the Flexible compensation of Rubber Expansion Joint and works in coordination with the customized adaptation of Flexible Metal Hose. It achieves sealing connection through Flange Adaptor and enhances maintenance convenience with the help of Dismantling Joint. Jointly safeguard the unidirectional flow of media with Duckbill Check Valve. Whether it is a light corrosion scenario or a lightweight demand project, aluminum elbows have become a reliable choice for pipeline system steering with their cost-effective solutions. ​
