What is a flange?
A flange is a metal disc utilized to sign up with pipelines. A gasket is repaired in between the 2 flanges to tighten up the seal. A flange is used to link two pipes or valves or tubes to form a piping network. They provide support and strength and prevent leakage.
Frequently bonded or screwed into pipes or valves, bolts attach flanges together. Flanges offer simple access to tidy or examine a piping system.
Made from many metals - Stainless Steel, Cast Iron, Ductile Iron, Carbon Steel, etc., these flanges vary in 'pressure class'.
Every flange is categorized under a pressure class, depending upon the capability of the flange to withstand a particular quantity of temperature level. Likewise, the type of metal used in figure out how much pressure it can hold up against.
So it can be presumed that various flanges can endure various temperatures (or pressures.) If the temperature level increases, the pressure rating of the flange decreases and vice versa.
What is an Orifice flange?
Orifice flanges are disc-shaped flanges which come with among the 3 flanges namely Slip-on, Threaded and Weld neck.
Main purpose:
Orifice flange is a device having welding ends, which allows it to hold an orifice plate undamaged.
Widely used with orifice meters, they measure the flow rate of either liquid or gases, that circulation through the pipe. The Orifice Flowmeter includes a thin Orifice plate, secured into orifice flanges.
An orifice plate, which is the gadget to determine the motion of the inner fluid or gas, is protected between two orifice flanges, which are attached to the pipe. The orifice plate consists of a small hole; with 2 pressure tap holes https://www.keepandshare.com/doc21/112893/copper-the-good-the-bad-and-the-ugly are drilled in each flange which helps in determining the pressure built inside the pipe.
A 'jack screw' fitted in between the two flanges, it makes it possible for to separate the flanges throughout evaluation or replacement procedure.
Use:
Industries where Orifice flange is used -
Heavy and light chemicals
Steel
Paper
Nuclear
Petrochemicals
Sewage treatment
Water treatment and circulation
Power Generation
Oil production and refining
Gas Processing and transmission
Chemicals
Therefore, these flanges play an important role during the maintenance period of the piping system. They are the best suitable for intricate pipeline networks.
