How does an ASTM A234 WPB short radius bend assist in constructing structural steel frameworks?
As the name implies, these bends have a short radius equal to the diameter of the pipe. An ASTM A234 WPB short radius bend can contribute to building frame systems in the construction sector. These get used for wall bearings, skeleton framing, and other distinctive load-bearing components.
Structural steel frameworks for buildings use beams and columns for different elements. These fittings fit right in because of their high tensile strength (415 MPa) and pressure-bearing capacity. They produce a smooth directional change and offer the flexibility of different sizes and curvatures.
What are the available sizes for an A234 grade WPB SR bend?
Clients can order sizes from ½ to 24 inches for seamless bends. A welded A234 grade WPB SR bend has more size options – up to 72 inches. You can select from multiple angles, including 45 and 180 degrees.
Manufacturers issue size charts for these fittings that show the diameter and nominal size.
What are the test certificates for an SA234 WPB SCH 40 45 degree short radius bend? Why are they important?
The routine test certificates include a Mill Test Certificate (MTC), a raw materials document, and a radiography report.
Manufacturers perform non-destructive tests to confirm the properties and performance of an SA234 WPB SCH 40 45 degree short radius bend. These tests include magnetic particle inspection, hydrostatic testing, ultrasonic examination, and the assessment of tensile strength.
Customers can order additional test certificates from third-party agencies or accredited laboratories. These documents ensure that the fitting is appropriate and safe for your application. They also confirm the chemical composition, properties, quantities, and additional customizations you may have ordered.
