45° flanged elbows are the diagonal direction-changing pipe fittings we supply, integrating the direction-changing function of a 45° elbow with a flanged bolted quick-installation structure. They are mainly used on pipe sections that require fine adjustment of pipeline angle, adjustment of drainage slope, or avoidance of installation dead zones. Compared with 90° elbows, 45° diagonal bends are more targeted in dispersing fluid impact and reducing pipeline stress. The products are manufactured according to standards such as ASME B16.9, ASME B16.5, GB/T12459, HG/T20592, DIN, and EN, with nominal diameters covering DN15-DN2000, and pressure compatibility for national standard PN10-PN160 and American standard Class150-Class2500. Materials are divided into three categories: carbon steel, stainless steel, and alloy steel, which can be selected according to medium type, working temperature, and corrosion conditions.
The 45° diagonal direction-changing design is suitable for pipeline slope adjustment and offset connection, and can reduce the resistance concentration and fouling problems caused by 90° right-angle turns. The flanged connection method eliminates the need for hot work welding during on-site installation, making disassembly, assembly, and later maintenance more convenient, and also supports reuse during pipeline network renovation. The products adopt an integral forming process, with smooth inner walls, flat flange end faces, and bolt hole positions configured according to standards, ensuring tight fitting during connection. We provide two specifications: long radius 1.5D and short radius 1.0D, as well as two forms: single flange and double flange, which can be selected according to pipeline space and connection requirements. In terms of materials, carbon steel, stainless steel, and alloy steel are covered, capable of matching different working conditions from conventional medium and low pressure to corrosive media, high temperature, and high pressure.
45° flanged elbows are mainly used in diagonal direction changes, slope adjustment, and offset connection positions in various pipeline systems. In municipal water supply and drainage and rainwater-sewage diversion projects, they are used for fine adjustment of pipeline slope to help avoid water and dirt accumulation. In heating and fire sprinkler systems, they are suitable for diagonal connections in locations with limited space in pipe galleries. In the chemical, pharmaceutical, and food and beverage industries, stainless steel materials are selected for corrosion-resistant and clean medium pipelines. In ship pipelines, offshore platforms, and seawater desalination systems where salt spray corrosion resistance is required, stainless steel or alloy steel styles can be selected. In thermal power steam pipelines, coal chemical high-temperature process pipeline networks, and high-pressure oil and gas transmission systems, alloy steel thickened styles can be selected.
Nominal diameters cover DN15-DN2000, and pressure compatibility includes national standard PN10-PN160 and American standard Class150-Class2500. Bending radius is divided into long radius 1.5D and short radius 1.0D. Connection forms include single flange and double flange. The material system includes carbon steel, stainless steel, and alloy steel, and specific grades can be confirmed according to medium and working conditions.

If you need to confirm specific configurations or request a quotation, please contact us and provide information such as dimensions, quantity, material, and pressure rating.
If the pipeline requires a right-angle turn and space is sufficient, a 90° elbow can be selected. If the scenario involves fine adjustment of pipeline slope, diagonal connection, dispersing fluid stress, or avoiding water and dirt accumulation, a 45° flanged elbow is more suitable. For specific selection, you can contact us to confirm according to pipeline routing and working conditions.
A single-flange 45° elbow has one end for welding and one end with a flange, suitable for mid-pipeline modification and local connections. A double-flange 45° elbow has flanges on both ends, allowing weld-free disassembly and convenient maintenance, suitable for process pipelines that require regular maintenance. You can choose based on the connection method and maintenance needs, and we can also assist with confirmation.
