Threaded Flanges

Also referred to as a screwed flange by any Threaded Flange Manufacturer, these flanges have a thread inside the flange bore. These threads aid the flange to be fitted onto a pipe, which in turn will have a set of matching male threads. Generally, a threaded flange is designed with the intention of being used in those areas that do not permit welding to be performed in the pipe area.  For instance, if welding were to be carried out in highly flammable areas, the result would lead to explosions and potential health hazards. Hence, Threaded flange is used in nuclear power or heavy oil refineries. Apart from proving to be an easy and speedy connection device, it is important to note that a Carbon steel threaded flange is not particularly suited to perform well in industries that have a high temperature and a high pressure setting.

Which means, the use of threaded Flanges is mostly utilized in air and water applications. Since these applications have low pressured systems with no thermal cycles, the threads of the ANSI B16.5 Threaded Flange are not loosed. A reducing flange is a special type of flange that is frequently used in projects that require the connections of different sized pipes. A Stainless Steel Threaded reducing Flange consists of a flange with a specified diameter, wherein the size of the bore is of a different and smaller diameter.
