Your Professional Short Radius Elbow Supplier
Short radius butt-weld elbows are supplied in carbon steel, stainless steel, and alloy steel for industrial piping systems. The product range covers 90° and 45° short radius configurations, with material grades, wall thicknesses, dimensions, and inspection requirements specified according to project requirements or applicable standards.
Short radius elbows utilize a 1D centerline radius, making them suitable for piping layouts where a tighter directional change is required and installation space is restricted.

Why Choose Us
Verified Material Traceability
Every production batch is tied to original mill test certificates. Heat numbers are permanently stamped or stenciled onto fittings, ensuring full transparency and compliance with strict project QA/QC audits.
In-House Forming and Machining Capabilities
Equipped with dedicated elbow pushing machines, hydraulic presses, and precision CNC machining centers, production processes remain controlled from initial blanking and hot/cold forming to final bevel machining.
Rigorous Dimensional and Non-Destructive Control
Dimensional compliance is verified against ASME B16.9 tolerances using calibrated gauges and templates. Additional non-destructive examination (NDE) and mechanical testing options are integrated based on project-specific demands.
Export-Proven Quality and Packaging Standards
Years of global project supply experience ensure that products meet international engineering standards. Items are safeguarded with proper end-cap protection and export-grade wooden crating designed to withstand long-distance maritime transport without damage or contamination.
Material selection aligns directly with piping design temperature, pressure, corrosion resistance, and applicable material specifications.
Carbon Steel: Grades include ASTM A234 WPB, ASTM A234 WPC, and ASTM A420 WPL6 for specified low-temperature service requiring impact testing.
Stainless Steel: Austenitic families include ASTM A403 WP304/304L, ASTM A403 WP316/316L, WP321/321H, and WP347/347H.
Alloy Steel: Elevated-temperature and high-pressure service options include ASTM A234 WP11, WP22, WP5, WP9, and WP91.
Material availability should always be verified against project material standards and purchase orders before production scheduling.
Quality Control and NDE Testing
To prevent installation rejections, quality control covers dimensional tolerances, material chemistry, and structural integrity. Inspection scopes vary by order requirement:
Dimensional & Visual
Check on bevel angles, root face, wall thickness thinning, and center-to-end tolerances.
Chemical & Mechanical
PMI (Positive Material Identification), tensile testing, and hardness verification.
Non-Destructive Examination (NDE)
Ultrasonic testing (UT), magnetic particle testing (MT), liquid penetrant testing (PT), or radiographic testing (RT) when specified.
Angle and Configuration Options
Elbow angles are extracted directly from isometric drawings, material take-off lists, or piping specifications:
90° Short Radius Elbow
Applied for direct, tight-turn directional changes in compact skid packages, equipment connections, and restricted utility runs.
45° Short Radius Elbow
Utilized for minor directional offsets within tight structural boundaries.
180° Short Radius Return
Applied in specific heat exchanger or hairpin configuration layouts governed by dedicated dimensional standards.
Manufacturing Workflow and Forming Equipment
Consistent mechanical properties and uniform wall thickness depend on controlled manufacturing sequences:
Raw Material -> Material Verification -> Cutting -> Forming (Pushing/Pressing) -> Heat Treatment -> Machining & End Beveling -> Dimensional Inspection
Production operations utilize heavy-duty elbow pushing machines, hydraulic press equipment, CNC lathes, and precision machining centers. Heat treatment parameters are adjusted according to material grade requirements (such as normalizing, quenching, and tempering) to relieve forming stresses.
Standards, Marking, and Documentation
Export orders must comply with recognized international standards to pass third-party inspection (TPI) and end-client audits:
Product & Material Standards: ASME B16.9, ASME B16.25 (Butt-welding ends), ASTM A234, ASTM A403, and ASTM A420.
Traceability and Documentation Packages: Heat number stenciling, Material Test Certificates (MTC in accordance with EN 10204 3.1 or 3.2), dimensional inspection logs, and NDE test reports.
Fit-up Alignment and Seaworthy Packaging
Transport protection and end preparation directly affect site installation speed.
End Preparation
Pipe ends are machine-beveled in accordance with ASME B16.25 to ensure proper root gap and smooth fit-up during site welding. Plastic caps are fitted to protect bevel edges from impact.
Seaworthy Packaging
Fittings are secured in export-grade fumigated wooden boxes or steel-strapped pallets, isolating stainless steel and alloy items from carbon steel contact to prevent surface contamination during ocean freight.
