ASME b16.47 Series A class 150 blind flange

ASME B16.47 Series A Class 150 Blind Flange

For connection purpose, one of the most suitable products for choice can be ASME B16.47 series A class 150 blind flanges. This is because these are one of the flange types, that do not have a bore, which undoubtedly restricts flow of liquid material through it. This is the only reason why they are widely demanded for pipe isolation, and even pressure vessels. This is mainly achieved because of their compliance with material standards. The material standards B16.47, tends to cover for dimensional, tolerance and performance of the material in high temperature and pressure conditions.

ASME b16.47 series a 150# blind flange and ANSI b16.47 SR b 150LB blank flanges for high-temperature applications in UAE

These material standards also ensure that series A BLRF flange is devoid of degraded performance, and that it is genuine. Most importantly, they are manufactured with the pressure rating under the class 150. But keep in mind that one can use ANSI B16.47 sr A cl 150 blank flanges within the temperature range of -20.2-930°F. Weakening properties are seen, if exceedingly below or above this temperature range.

Within this temperature range, it offers excellent resistance to many corrosive environments. Most importantly, simplistic installation alternatives are offered on its use case and that it also is cost-affording.

Many of the listed suppliers can supply ANSI b16.47 Sr a 150 blind flange and series a blank flange at dealer price in the middle east, check sizes and availability

You can save 30%-40% cost when ordering ASME b16 47 SR A CL 150 blind flange and series A BLRF flange directly from manufacturers in the middle east and Asia
B16.47 series blind flanges in large diameter, check SR A 150# blank flanges pressure rating, weight & dimension

All this is achieved, only when the product is tested as per the below mentioned testing standards. It evaluated for the performance, quality and non-degraded properties, without altering the actual dimensions of ASME B16.47 series A 150# blind flange.

  • Non-destructive testing: this testing method evaluates for the performance and quality assured services.
  • Eddy current testing: to detect flaws or other defects such as dents or cracks, electronic probes are employed to pass throughout the material.
  • Ultrasonic testing: for evaluating non-degraded performance, high frequency ultrasonic waves are passed throughout the material.

Adding to this, one can even demand for MTC standards for ANSI B16.47 sr B 150LB blank flanges. This standard includes for the product specifications, after being manufactured by cutting, forging and casting methods. It is this manufacturing methods, that installs good strength properties into ANSI B16.47 sr A 150 blind flange.

With that said, it comes in the size range of NPS 26 – NPS 60. Many use cases often reveal for accurate and custom specified dimensions. In such cases, customers are highly advised to approach, where listed suppliers at this platform can quote affording and reasonable prices for ASME B16 47 sr A cl 150 blind flange. The other way around can be checking for alternative material, grade or products.
