BLIND FLANGES / BLRF / RFBL / BLFF / FFBL / BLRTJ
Blind flanges may not be the most glamorous component in the world of piping systems, but they are certainly one of the most important. These handy devices are used to cap off piping systems, preventing the flow of fluids or gases. They are also used to facilitate maintenance, inspection, and cleaning processes. Despite their importance, many people are still unfamiliar with BLRF flanges and their various applications. We will help you understand from the different types and materials available, to their installation and maintenance, which will provide you with all the information necessary to make informed decisions about your piping system needs. So, whether you are a seasoned professional or a curious beginner, read on to discover the ins and outs of blind flanges.
BLFF pipe flanges are used to seal the end of a piping system or pressure vessel openings to prevent flow. BLRTJ flanges are mainly used for pressure testing the flow of liquid or gas through a pipe or vessel. These flanges also allow easy access to the pipe in the event that work must be done inside the line. Tesco Steel & Engineering manufacture a wide range of high quality RFBL Flanges in India. We offer these FFBL flanges in ASME/ANSI/DIN standards.
