Steel Pipe Elbows
Our industrial steel elbows are precision-engineered to change the direction of fluid or gas flow within a piping system. Available in 45°, 90°, and 180° configurations, these fittings are manufactured to withstand high-pressure environments, extreme temperatures, and corrosive conditions across the oil, gas, and power sectors.
1. Technical Specifications
Degrees:45°, 90°, 180° (Short Radius & Long Radius).
Radius Types:*Long Radius (LR):Center-to-face distance is 1.5 times the nominal pipe size (R=1.5D).
Short Radius (SR):Center-to-face distance is equal to the nominal pipe size (R=1.0D).
Size Range:1/2" to 72" (DN15 – DN1800).
Wall Thickness:SCH 5S to SCH XXS.
2. Material Grades & Standards
We offer a comprehensive range of materials to ensure chemical compatibility with your pipeline:
Carbon Steel:ASTM A234 WPB, WPC; ST37.2, A105.
Stainless Steel:ASTM A403 WP304/304L, WP316/316L, 321, 310S.
Alloy Steel:ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91.
Low Temperature:ASTM A420 WPL3, WPL6.
High Yield:MSS-SP-75 WPHY 42, 52, 60, 65, 70.
3. International Manufacturing Standards
All elbows are produced and strictly tested in accordance with global industrial requirements:
ASME/ANSI B16.9(Factory-Made Wrought Buttwelding Fittings)
ASME B16.11(Forged Fittings, Socket-Welding and Threaded)
DIN 2605(Steel Butt-Welding Pipe Fittings; Elbows)
JIS B2311 / B2312 / B2313
EN 10253(Butt-welding pipe fittings)
4. Key Features & Applications
Flow Efficiency:Smooth internal surfaces minimize friction and turbulence in high-velocity systems.
Versatile Connections:Available in Butt-Weld (BW), Socket-Weld (SW), and Threaded (NPT/BSPT) ends.
Surface Treatment:Provided with Black Vanish, Anti-rust Oil, Hot-dip Galvanized, or Pickled & Passivated finishes.
Broad Application:Critical for Petrochemical Refineries, Offshore Platforms, Power Generation, Water Treatment, and Shipbuilding.
5. Quality Control & Logistics
Testing:100% Dimensional Inspection, Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI), and Hydrostatic Testing.
Certification:Fully compliant withMTC (EN 10204 3.1); third-party inspection (SGS, BV, TUV) accepted.
Packaging:Securely packed in seaworthy wooden cases or on pallets with protective wrapping to prevent transit damage.
