Pipe flange

Manufacture of Pipe flanges, RTJ Flanges, Ring Type Joint Flange, Spectacle Blind Flange, ASME B16.48 Class 1500 Pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Note: - Values for minimum flange thickness, C, and overall length, D, are detailed in the flange tables. - For ring joint tolerances Ring joint facing dimensions - ASME/ANSI B16.5 and B16.47 Series A (MSS SP-44) and Series B (API 605) (Continued)

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange. Pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Note: - Values for minimum flange thickness, C, and overall length, D, are detailed in the flange tables. - For ring joint tolerances see page 8-9. Ring joint facing dimensions - ASME/ANSI B16.5 and B16.47 Series A (MSS SP-44) and Series B (API 605)

A figure-8 blank (also called a Spectacle Blind Flange) is a pressure-retaining plate with one solid end and one open end connected with a web or tie bar.
