Specialized UNI Flange Manufacturer, UNI Flange Dimensions, Weight, Pressure Rating.
Marcel Piping Projects Supply PVT LTD is well-known manufacturers of UNI Flange in India. Uni-Flange eliminates the problems of pre-engineered, prefabricated piping systems. Pipe fabrication can be performed on site, using plain end pipe, a pipe cutter and a wrench. No threading, welding or grooving is necessary. The Uni-Flange eliminates the need to rely on off-site fabricators and machine shops. It is ideal for projects that involve retro-fitting or renovation of existing piping systems.
flange uni pn16 dimensions in mm may be freely rotated before any of the flange bolts are to be inserted and tightened. This in turn facilitates bolt hole alignment along with the facing flange, which proves to be beneficial. Generally, Pre-fabricated piping systems tend to not offer this advantage on installation.
Unlike conventionally used threaded or welded flanges, the uni flange series 1400 permits for pipe deflection during installation, which means that the uni flange torque is able to make a connection when other means fail. The Stainless Steel Uni Flange offers built-in end restraint, without tie rods or other forms of anchoring, which were deemed necessary for normal working pressures. Although special considerations could be required for pump surges.
