Flange is an integral part of pipe fittings typically used as a connecting component either to fixed or rotating parts. An average flange represents a paired object of ring or disc-shaped form. The flanges uk are mounted through diametrically arranged holes using a flange connection screw: bolts or studs, tightening the two flanges. Flanges may vary in size, type of connection between them, front form and in seals options between two mating surfaces of the flange. The pressure the pipelines flanges handle starts from 10-13 mbar and reaches the impressive 220 bar in the most advanced facilities.
There are several forms of flanges production: manufacturers produce steel flat flanges, neck flanges, loose flanges on the ring, secured by welding, and, of course, bespoke flanges. Flanges form the first group serve as connecting elements between the flange itself and the other flange element of the system. The flanges are typically attached to the pipes via threaded or welded joints. Such flanges are designed to withstand the temperature conditions of -75 – 450 degrees. However, it should be taken into account that depending on the diameter of the pipe, the assumed values of pressure and regional conditions flanges may have up to ten subtypes of spacer compounds. Flat flanges are able to withstand even greater temperature ranges, in this case the flanges are connected by welding, without using spacers between the flat flanges of additional materials. Neck flanges are mounted back to back; the flanges of this type are oftentimes used to mounting various devices by connecting flanges with various fittings and pipe accessories.
The flanges represent the parts of connective tubing, shafts and containers. Flanges are primarily designed for connecting different products with the main pipeline valves. Furthermore, they are used for bonding together the individual pipe sections or the connection to the equipment. Flange reinforcement provides strength, integrity and simplifies the process of assembling and disassembling complex constructions.
