ASME B16.47A ASTM A105 weld neck flanges and blind flanges shipped

In mid-March,ASME B16.47A ASTM A105 weld neck flanges and blind flanges ordered by Saudi customers were shipped. The ASME B16.47A standard specifies large diameter steel flanges (NPS 26 through NPS 60) that are typically used in high-pressure and high-temperature applications. The ASTM A105 material specification covers forged carbon steel piping components, including weld neck flange and blind flange, that are suitable for use in pressure system applications.

The manufacturing process for ASME B16.47A ASTM A105 weld neck flanges and blind flanges typically involves the following steps:

1.Material Selection: The first step in the manufacture process is the selection of the raw material. The raw materials used for manufacturing weld neck flanges must meet the requirements of ASTM A105 specification. ASME B16.47A ASTM A105 blind flanges are typically made from carbon steel or alloy steel such as A105 or A350 LF2. The material should be of the correct size and quality to ensure the flanges are able to withstand high-pressure applications.

2.Cutting: The selected material is then cut to the desired size and shape using a saw or other cutting equipment.

3.Heating & forming: The cut material is heated to a high temperature to make it malleable. The heated material is then placed in a forming press where it is shaped into the desired flange.

4.Forging: The heated material is then forged into the desired shape using a hydraulic press. This process involves the application of a tremendous amount of pressure, shaping the material to suit the flange’s specific design.

5.Machining: After forging, the flange requires precise machining to ensure accurate measurements, flatness, and smoothness. This process involves the use of lathes, mills, and other machining equipment.

6.Inspection: The finished flange is then inspected to ensure it meets the required standards and meets customer specifications. This includes measuring the flange’s dimensions, checking its flatness and smoothness, and verifying the material quality.

7.Surface Preparation: The final step involves preparing the flange’s surface for delivery. The flange is typically sandblasted, cleaned, and coated with a layer of protective oil to prevent rusting during transportation.

8.Packing & Shipping: The finished flange is packed securely to protect it from damage during transit and is sent to the customer as per their specification and requirements.
