Steel pipe elbows are basic connecting components used in piping systems to change the direction of the medium flow. This product series is applicable to pipeline installation scenarios in petroleum, chemical, electric power, water treatment, and construction engineering. The specifications cover commonly used angles (45° / 90° / 180°) and various bend radii (1D / 1.5D / 3D), meeting diverse pipeline layout requirements.
Part 2: Key Parameters and Processes (Objective Statement)
Material Options (as actually supplied)
Carbon steel series (Q235 / 20#): Suitable for conventional low-pressure water heating and structural support piping.
Stainless steel series (304 / 316L): Suitable for food, pharmaceutical, and coastal areas or working conditions with corrosive media.
Alloy steel series (12Cr1MoV / 15CrMo): Suitable for high-temperature, high-pressure steam and boiler-related piping.
Forming Process
Formed by pushing/pressing/welding (select as applicable) in a single operation or through multiple processes, ensuring relatively uniform wall thickness transition and reducing stress concentration points. Weld joints (if any) are subject to non-destructive testing to ensure fusion quality meets corresponding standards.
Surface Treatment
Before delivery, anti-rust coating, hot-dip galvanizing, or pickling and passivation treatment can be applied as required to suit protective needs in different environments.
Part 3: Applicable Standards (Verifiable)
This product series is strictly manufactured in accordance with the following standards (please select as applicable, ensuring authenticity):
National standard: GB/T 12459 / GB/T 13401
American standard: ASME B16.9 / ASTM A234
Dimensional tolerances and wall thickness schedules (Sch10 – Sch160) support customisation according to drawings.
Part 4: Purchasing Recommendations (Gentle Guidance)
Please confirm the design pressure, temperature, and medium properties of the pipeline, and select the corresponding material and wall thickness grade.
For on-site welding installation, it is recommended that welders with appropriate qualifications perform the work and follow the welding procedure specifications.
For bulk purchases, please contact customer service with your technical parameters, and we will verify the specification compatibility for you.
