Key benefits:
- Full angle & radius coverage - 45°/90°/180°, LR & SR in one product line, so a single supplier can match every routing angle on your isometric drawings.
- Wide size span - seamless 1/2"–36", welded 5"–110" - the same spec sheet covers small utility branches through large trunk pipework.
- Full schedule range - STD, XS, XXS through Sch160 - wall thickness matched to your pressure class without switching vendors.
- Multi-standard compliance - ANSI B16.9, MSS SP-75, EN10253-2, JIS B2313 - one SKU clears US, EU and Asian project specifications.
- ISO 9001 / 14001 / 45001-certified production (Cert. No. 1952024Q0837R0S / 1952024E0437R0S / 1952024S0379R0S) - documentation ready for customs and EPC contractor QA audits.
- Flexible surface treatment - black painting, color painting, galvanized or epoxy coating - matched to your site's corrosion environment at order time.

Why Choose This Elbow
Full schedule range from STD to Sch160 - wall thickness is matched to your pressure rating at the material stage, not reworked afterward. This gives project engineers a documented wall-thickness-to-pressure-class match ready for design review, without ordering a separate custom run.
Wide seamless-to-welded size span (1/2"–36" seamless, 5"–110" welded) - a single elbow line covers small instrument branches through large trunk lines. This means fewer supplier changeovers across a project's size range, and consistent quality control from one factory for every diameter your BOM calls for.
Multi-standard compliance (ANSI B16.9, MSS SP-75, EN10253-2, JIS B2313) - the same production line is qualified against the four dimensional standards most referenced across US, EU and Asian project specs. That reduces the risk of a spec mismatch being caught late in customs or site inspection.
Configuration Options
Angle & Radius
Select 45°, 90° or 180°, in either Long Radius (LR) or Short Radius (SR), to match your routing geometry.
Size & Wall Thickness
Seamless 1/2"–36" or welded 5"–110", from STD/XS/XXS through Sch160, specified against your pressure class.
Material Grade
Standard ASTM A234 WPB, or St37.2, St35.8, API 5L Gr.B / X42 / X52 / X60 / X65 / X70 for pipeline-grade projects.
Surface Treatment
Black painting, color painting, galvanized, or epoxy coating - selected to suit the corrosion environment of your installation site.
Application Scenarios
Petroleum & Refinery Piping
Process lines demand fittings that hold up to high-temperature, high-pressure media without repeated shutdowns. Our A234 WPB elbows are produced to ANSI B16.9 dimensional tolerances and heat-treated in-house, supporting continuous-duty refinery and upstream piping runs.
Fertilizer Plants
Corrosive process media shortens the service life of standard fittings. Epoxy or galvanized surface treatment options extend elbow service life in fertilizer plant piping without changing the base material grade.
Power Stations
Power plant piping specs often mix ANSI and JIS references across equipment sourced from different regions. Multi-standard compliance (ANSI B16.9 / JIS B2313) means one elbow spec can satisfy both.
Shipbuilding
Shipboard piping needs tight dimensional consistency for pre-fabricated modular sections. LR/SR options in both seamless and welded construction let fabrication yards standardize on one supplier across a vessel's piping package.
Onshore Platforms
Platform piping is exposed to harsh outdoor conditions over long service periods. Sch80/Sch160 heavy-wall options and galvanized/epoxy coating support long-term outdoor installations without frequent maintenance cycles.
OEM / ODM Support for Project & Branding Requirements
Production runs from raw material re-inspection through cutting, heating & pushing to form, shaping, heat treatment, groove machining, surface treatment and final inspection - the same process flow used to fulfill custom angle, size, material grade and surface treatment combinations, plus project-specific packaging and labeling.
