Flange
Flanges play a pivotal role in piping systems by allowing easy access for maintenance, inspection, and modification.
They provide a means to connect or disconnect pipes and equipment without the need for welding, which simplifies installation and reduces downtime during repairs or upgrades.
Additionally, flanges facilitate the alignment of pipes, ensuring a proper fit and minimizing stress on the system.
Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels.
Industries where flammable, volatile, toxic or corrosive substances are being processed have greater need of special protection at flanged connections.
Flange guards can provide that added level of protection to ensure safety.
Unique pressure classes for piping can also be developed for a process plant or power generating station; these may be specific to the corporation, engineering procurement and construction (EPC) contractor, or the process plant owner.
[3] Flanges come in various types, each designed to meet specific requirements based on factors such as pressure, temperature, and application.
The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details (see ASME Code Section VIII Division 1 – Appendix 2).
Flanges in the rest of the world are manufactured according to the ISO standards for materials, pressure ratings, etc.
Theoretically, the heel contact will be maintained for pressure values up to 1.8 times the flange rating at room temperature.
Thus, this prevents corrosion of the flange faces, the stressed length of the bolts and the seal ring.
This however depends on the outer dust rim to remain in satisfactory contact and that the inside fluid is not corrosive in case of leaking into the bolt circle void.
Most trains and trams stay on their tracks primarily due to the conical geometry of their wheels.
They also have a flange on one side to keep the wheels, and hence the train, running on the rails when the limits of the geometry-based alignment are reached, either due to some emergency or defect, or simply because the curve radius is so small that self-steering normally provided by the coned wheel tread is no longer effective.
Several different microwave RF flange types exist, such as CAR, CBR, OPC, PAR, PBJ, PBR, PDR, UAR, UBR, UDR, icp and UPX.
Traditional telemark and cross country boots use the 75 mm Nordic Norm, but the toe flange is informally known as the "duckbill".
New cross country bindings eliminate the flange entirely and use a steel bar embedded within the sole instead.
