Description
6-Inch Carbon Steel 90-Degree Butt Weld Elbow – A Reliable Turning Hub for Fluid Pipelines
In industrial piping systems, the 6 inch steel pipe 90 degree elbow is widely used in petroleum, chemical, water supply, and municipal engineering fields.
Specifications of 6 inch steel pipe 90 degree elbow
To ensure dimensional fit and pressure-bearing capacity under various working conditions, AIFN strictly complies with ASME B16.9 and GB/T 12459 standards. The following table shows typical specifications for this product, clearly presenting key data for carbon steel 90 degree elbow dimensions:
| Parameter | Specification Details | Remarks |
|---|---|---|
| Product Name | 6-inch Carbon Steel Long Radius Elbow | Seamless / welded (ERW) optional |
| Nominal Diameter (DN) | DN150 | Fits 6-inch standard pipe |
| Execution Standard | ASME B16.9 / GB/T 12459 | Customizable to DIN / JIS standards |
| Bend Radius (R) | Long Radius (LR, R=1.5D) or Short Radius (SR) | LR is more favorable for smooth medium flow |
| Wall Thickness Schedule | Sch 40 / Sch 80 / Sch 160 | Supports schedule 40 steel pipe elbow and thicker custom options |
| Connection Type | Butt Weld / Socket Weld | Suitable for high-pressure, high-temperature environments |
| Bevel/End Preparation | Bevel End (BW) / Plain End (SW) | Weld ends conform to standard bevel angles |
Material Properties and Manufacturing Processes
Choosing the right pipe elbow carbon steel 90 degree supplier is the first step toward project success. AIFN supplies 6-inch elbows made from high-quality A106 Gr.B or A234 WPB carbon steel blanks, manufactured by cold pushing or hot pressing forming processes.
This process not only ensures uniform wall thickness and eliminates internal stress, but also endows the product with excellent mechanical properties.
-
Strong corrosion resistance: For buried or humid environments, the inner and outer surfaces are treated with anti-corrosion coating or hot-dip galvanizing. Notably, in the pipeline network upgrade project of the Jimo District Waterworks in Qingdao City – where the high groundwater table posed extremely stringent corrosion resistance requirements – the client ultimately selected AIFN’s 6-inch carbon steel elbows. Thanks to their stable material and reliable wall thickness design, these elbows have been successfully used in long-term buried applications at critical locations, effectively resisting electrochemical corrosion from soil and water quality. They have operated stably to date, significantly reducing maintenance frequency.
-
Precise geometric dimensions: As a 6″ steel pipe 90 degree elbow, its end outer diameter, wall thickness, and center-to-end dimensions strictly conform to standard tolerances, ensuring zero misalignment during on-site fit-up and welding. This greatly improves welding efficiency and non-destructive testing (NDT) pass rates.
Application Scenarios and Solutions
In addition to large-scale water treatment facilities, this elbow plays an indispensable role in the following scenarios:
-
HVAC systems: Used for directional changes in chilled water and cooling water piping, effectively reducing system pressure drop.
-
Petrochemical pipe racks: In high-temperature, high-pressure hydrocarbon media transmission, long-radius elbows reduce erosion and corrosion, forming the cornerstone for safe pipeline operation.
-
Fire protection networks: Provide standard directional connections for fire pump outlets and ring mains, ensuring smooth water flow in emergency conditions.
If you are looking for a competitive 90 degree steel pipe elbow price quote, or require customized solutions for specific pressure ratings (e.g., Class 150, Class 300), AIFN’s professional technical team is always ready to provide selection support and detailed drawing services. We are committed to making every connection safe and reliable.
