UNI Flange Supplier, Manufacturer in India
Unichem Steel & Alloy Pvt. Ltd. is a Professional UNI Flanges Manufacturer in India, specialize in manufacturing Uni Flanges in several types and sizes. The UNI Flanges Series 900 provides a power-tight Rigid flanged connection, eliminating the requirement for solvent-welding, tie rodding, harnessing, and other sorts of restraint. Uni-Flange eliminates the issues of pre-engineered, prefabricated piping systems. Pipe fabrication is often performed on-site, employing a plain end pipe, a hand tool, and a wrench. No threading, welding, or grooving is important. The Uni-Flange eliminates the requirement to believe off-site fabricators and machine shops. it’s ideal for projects that involve retrofitting or renovation of existing piping systems. Uni-Flanges are often freely rotated before the flange bolts are inserted and tightened. Pre-fabricated piping systems don’t offer this installation advantage. The Uni-Flange will permit pipe deflection during installation. This implies the Uni-Flange can make the connection when other means can’t. The Uni-Flange offers built-in end restraint. No tie rods or other sorts of anchoring are necessary for normal working pressures. Special considerations are also necessary for pump surges. The Uni-Flange are often easily disassembled and slid back on the pipe. This facilitates the removal of the flanged equipment. When the equipment is to get replaced, simply drop it in and re-install the Uni-Flange. Threaded and welded flanges don’t offer this feature.
