Nickel Blind Flanges (Blrf) Stainless Steel Blind Flanges are mostly used to seal the end or opening of a pipe, which is why they come without a bore. This comes in handy for inspection and pressure tests, as it allows quick access to the pipe. We offer ANSI B16.5 Blind Flanges to the high h pressure application industries in numerous thread types and hub requirements as well as in hard-to-find metals categories like Monel, Hastelloy, Titanium, Inconel, etc.
ASME B16.5 BLRF Flanges are Blind Raised Face Flanges that comply with the ASME B16.5 standard for pipe flanges & flanged fittings. These flanges are designed for pipes or fittings without a raised face. The Blind Flanges are commonly used to seal the end of a pipe or fitting and are used in applications where the piping system needs to be closed or blocked off.
ANSI B16.5 Blind Flanges are used to close the end of a piping system or a pressure vessel. These flanges are commonly used in applications where the piping system needs to be closed off for maintenance, inspection, or repair. They are also used in systems where the flow needs to be stopped temporarily, such as during testing or cleaning. Blind Flanges are designed to withstand high pressure & temperature, making them suitable for various industrial applications.
The benefits of using B16.5 Blind Flanges include easy installation, versatility, and safety. These flanges are easy to install & remove, making them ideal for applications requiring frequent maintenance or inspection. They are versatile & can be used in various applications, from low-pressure to high-pressure and high-temperature systems. Also, using Blind Flanges can improve safety by providing a seal that prevents leaks and reduces the risk of accidents.
