ASME B16.5 Flange

What is the difference between a bolt hole pattern and a bolt circle diameter in ASME B16.5 flange?

The bolt hole pattern is the arrangement & number of bolt holes in a circular pattern. The bolt circle diameter is the diameter of the imaginary circle passing through the centers of the bolt holes. ASME B16.5 flange manufacturer in UAE uses it as a reference for positioning & aligning the flange during installation. This ASME b16.5 flange dimensions ensure accurate bolt hole alignment with the mating flange or equipment.


How do you read a dimension and weight chart for ANSI B16.5 flange?

  • Look for the flange size column in the chart. This is indicated by the nominal pipe size or the flange's OD.
  • Find the corresponding row for the desired pressure class or rating, like ansi b16 5 class 900 flange dimensions.
  • The chart will provide dimensions such as the ANSI B16.5 flange thickness, OD, ID, bolt hole diameter, and others. Read these values for the specific flange size and class.
  • The weight column in the chart will provide the weight of the flange per unit.

What are the different testing requirements for exporting ASME B16.5 material?

  • Conducting tests like chemical composition analysis, mechanical properties testing and non-destructive testing to ensure the ASME B16.5 material meets the specified requirements.
  • The flanges should undergo dimensional inspection to verify that they conform to the specified dimensions, tolerances and geometric requirements.
  • Pressure testing is conducted to verify the integrity and ability of flange ansi b16.5 to withstand the specified pressure without any leakage or failure.
  • Visual inspection is performed to assess the surface condition, finish and overall quality of the flanges. The inspection will ensure they are free from defects, corrosion, or other visual anomalies.

What is the typical price difference between standard and custom-made B16.5 flanges?

Custom-made flanges are specifically manufactured to meet unique requirements. This can include non standard ansi b16 5 class 1500 flange dimensions, special materials or unique designs. Due to the additional time, effort and resources involved in producing custom B16.5 flanges, they tend to be more expensive than standard flanges. The extent of the price difference can depend on factors like the complexity of customization, quantity ordered and market conditions.

What are the different types of bolting used with ASME B16.5 standard pipe flanges?

  • Stud Bolts- threaded rods with threads on both ends. They are used with two nuts to secure the flanges together.
  • Hex Bolts- they have a hexagonal head and a threaded shaft. They are used with a matching nut to fasten the ASME B16.5 standard pipe flanges.
  • Socket Head Cap Screws- they come with a cylindrical head and an internal hex socket drive. They are often used with a corresponding socket wrench to tighten the bolts.
  • Tension Control Bolts- they have a specialized design that allows for controlled pre-load tensioning. They often feature a spline or sheared section that breaks off once the proper tension is achieved.

What is the role of quality control in forged steel flange, and how is it ensured?

Quality control ensures the reliability & performance of forged steel flanges. It involves implementing systematic processes and procedures. This is to monitor & evaluate the flanges' characteristics and adherence to specified standards. Some quality control measures followed by forged flanges manufacturers are visual inspection, dimensional verification, non destructive testing, material inspection, etc.

Quality control is ensured through strict adherence to established standards & procedures, trained and qualified personnel and regular audits & inspections. Compliance with relevant industry standards also helps maintain the quality of the flanges. Manufacturers often have quality management systems to further ensure consistent quality control practices.


How does the wall thickness affect the pressure rating of a ASME flange standard?

The wall thickness of asme flange standard plays a significant role in determining its pressure rating. In ASME B16.5, the pressure rating of a flange is classified based on different pressure classes. The wall thickness of a flange affects its strength and ability to withstand pressure. Thicker walls provide more material and structural integrity, allowing the flange to handle higher pressure loads. As the pressure rating increases, the required wall thickness of the flange also increases. This helps to ensure its integrity and prevent failure under pressure.
