ASME B16.47 Series B Class 900 blind flange

ASME b16.47 series b class 900 blind flange

For covering larger use case, ASME B16.47 series B class 900 blind flanges are widely recommended. This is mainly because it covers for the flanges which are comparatively larger in size, which comply with ASME B16.47 material standard.
This standard covers for the dimensional aspects for ASME B16.47 series B class 900 blind flange dimensions, where it is available within 26″ to 60″, with the pressure rating lying under the class 900. The predecessor to this standard was MSS SP-44. Not only this, materials of ANSI B16.47 series B class 900 blank flanges are the same as the flanges that come under ASME B16.45, but it is different for flanges, which are of nickel alloys.

With the material compliance comes an added benefit of using it. When suggested for use case, it offers simplistic mechanic design properties. Not only this, the heat treatment of B16.47 900lb series B BLRF flange also enhances its quality. Most importantly, in scenarios where corrosion resistance is needed, this material shows excellent resisting properties.

This is one of the most crucial factors that must be seen before choosing any products. Also, it is highly advised for customers to also check for the material certification and test results of the below mentioned testing standards

  • Non-Destructive testing: without altering physical dimensions, ASME B16.47 cl 900 sr B blank flange are evaluated for their performance and quality.
  • Eddy current testing: for ensuring that flanges are devoid of any defects or flaws, electronic probes are passed throughout the material.
  • Hydrotesting: out of all testing methods, this method of testing is one of the most favourite ones for customer. This is because it is demanded only by the customers to be sure on their part for B16.47 series B cl900 blind flanges being genuine. This test is however not a compulsory testing method.

But ideally, be sure on your part if custom or specific dimensions are aspired. If such cases are considered, then either customers can demand for price quotations from the listed suppliers at Or they can check for alternate grades or materials. Make sure that these price quotations and demands are as per the material standards too.
