Short radius elbow SR (R=1.0D) is a compact pipe fitting launched by the Guojie brand, with a bending radius of only 1 times the pipe nominal diameter. Compared with long radius elbows, it saves more space and is suitable for secondary pipelines with limited installation space. The product complies with GB/T12459, GB/T13401 and ASME B16.9 standards, and can also be customized according to ASME B16.28. Standard angles of 90°, 45°, and 180° are available, while 30° and 60° are non-standard customized. Connection types include butt welding, socket welding, threaded, and flanged. The forming processes include hot pushing, extrusion, stamping, and bending. A variety of materials are available, and customization for reducing, thickened, insulated, wear-resistant and anti-corrosion types is possible. Fluid resistance is relatively high, so please choose carefully for main pipelines with high pressure and high speed. We provide selection guidance, support non-destructive testing, and standard angles are in stock. Welcome to contact us to confirm the specific configuration.
Overview
Short radius elbow SR (R=1.0D) is a pipe fitting with a bending radius equal to 1 times the pipe diameter. Compared with long radius elbows, it is more compact and can effectively save installation space. It is mainly used to change the flow direction of pipeline media, and is particularly suitable for secondary pipelines in space-constrained areas, such as equipment nearby connections, narrow pipe galleries, and internal pipelines within units. Due to relatively high fluid resistance, it is not recommended for high-pressure, high-speed main pipelines. We provide products with multiple angles, multiple materials, and multiple connection methods, and support non-standard customization to meet different engineering requirements.
Key Features
1. Compact design: R=1.0D short radius, saves space, suitable for narrow environments. 2. Multiple angle options: 90°, 45°, 180° are regularly in stock, 30°, 60° can be customized. 3. Multiple materials and connections: carbon steel, stainless steel and other materials are available, connection forms include butt welding, socket welding, threaded, and flanged. 4. Reliable quality: regular forming, stable dimensions, traceable raw materials, supporting non-destructive testing. 5. Fast delivery: standard angles are well stocked, minimum order quantity of 1 piece, meeting urgent needs. 6. Customization capability: special customization such as reducing, thickened, insulated, wear-resistant and anti-corrosion is available.
Applications
Short radius elbow SR is applicable to industries such as petrochemical, electric power and thermal energy, coal chemical, sewage treatment, and municipal engineering. Typical scenarios include: pipeline direction changes in narrow pipe galleries, close-range equipment connections, internal supporting pipelines within units, and partial pipeline renovation. Due to relatively high fluid resistance, it is limited to secondary pipelines in space-constrained areas; high-pressure, high-speed main pipelines are not recommended.
Specifications
Core parameters include bending angle, radius of curvature (1.0D), nominal diameter DN, wall thickness schedule SCH, material grade, and connection form. Implementation standards are GB/T12459, GB/T13401, ASME B16.9; non-standard angles follow ASME B16.28 or customer drawings. All parameters need to be comprehensively confirmed in combination with the project medium, temperature, and pressure. You are welcome to provide detailed requirements, and we will assist with product selection.
Procurement & Delivery
Standard angles (90°, 45°, 180°) are kept in stock, supporting minimum order quantity of 1 piece, with shipment within 1-3 working days. Small and medium diameter ordinary non-standard parts take 10-15 working days; large diameter, alloy steel, 30°/60° non-standard and other special customizations take 15-30 working days. Foreign trade orders reserve time for packing and customs declaration; specific delivery time is subject to the contract. For packaging, small diameters use anti-rust paper and plywood wooden cases, medium and large diameters use solid wood pallets and stretch film, export packaging includes shipping marks and desiccant, and fumigation is supported.
Service & Support
We provide technical guidance for product selection to help distinguish the applicable scenarios of SR/LR elbows. We can provide material certificates, inspection reports, and complete export documentation. Non-artificial body quality issues are handled according to the contract terms. In terms of logistics, we follow up on progress, and for foreign trade orders, we assist in verifying the packing list and shipping marks. We also answer questions regarding storage and usage, but we do not assume responsibility for quality issues caused by welding, modification, or incorrect product selection.
FAQ
What is the difference between short radius elbow SR and long radius elbow LR?
The bending radius of short radius elbow SR is 1 times the pipe diameter (R=1.0D), which has a compact structure and saves space, but the fluid resistance is relatively large; the bending radius of long radius elbow LR is 1.5 times the pipe diameter, which has low fluid resistance and is suitable for high-pressure, high-speed main pipelines. For secondary pipelines with space constraints, SR can be selected; otherwise, LR is recommended.
What angles are supported for short radius elbow SR?
We stock 90°, 45°, and 180° standard angles with ample inventory. 30° and 60° are non-standard custom options that require drawings or detailed parameters, and we will confirm after evaluating the manufacturing process.
Can short radius elbow SR be customized?
Yes. We support customization such as reducing diameter, thickening, insulation, wear-resistant and anti-corrosion treatments, and we can also produce according to national standards, American standard ASME B16.28, or customer drawings. Special customizations such as large diameter, thick wall, and alloy steel require process evaluation; please feel free to contact us for confirmation.
What is the delivery time for short radius elbow SR?
Standard angles (90°, 45°, 180°) are in stock and ship within 1-3 working days; ordinary non-standard small and medium diameters ship within 10-15 working days; special customizations such as large diameters, alloy steel, and 30°/60° non-standard angles ship within 15-30 working days. Foreign trade orders need to reserve customs clearance time, and the specifics are subject to the contract.
What standard does the short radius elbow SR comply with?
We comply with GB/T12459, GB/T13401, and ASME B16.9 standards. Non-standard angles can be produced according to ASME B16.28 or customer drawings. Nondestructive testing is supported, and material certificates and inspection reports can be provided.
