What is a flange?
A flange is a metal disc used to sign up with pipelines. A gasket is repaired in between the two flanges to tighten up the seal. A flange is utilized to link two pipes or valves or tubes to form a piping network. They supply support and strength and prevent leak.
Commonly welded or screwed into pipes or valves, bolts connect flanges together. Flanges offer simple access to tidy or examine a piping system.
Made of lots of metals - Stainless-steel, https://www.keepandshare.com/doc18/23394/10-misconceptions-your-boss-has-about-duplex-steel Cast Iron, Ductile Iron, Carbon Steel, etc., these flanges differ in 'pressure class'.
Every flange is classified under a pressure class, depending on the capability of the flange to withstand a particular quantity of temperature level. Likewise, the kind of metal used in identify just how much pressure it can hold up against.
So it can be inferred that various flanges can stand up to various temperature levels (or pressures.) If the temperature level increases, the pressure ranking of the flange decreases and vice versa.
What is an Orifice flange?
Orifice flanges are disc-shaped flanges which come with among the three flanges particularly Slip-on, Threaded and Weld neck.
Main purpose:
Orifice flange is a gadget having welding ends, which enables it to hold an orifice plate undamaged.
Commonly utilized with orifice meters, they determine the circulation rate of either liquid or gases, that circulation through the pipe. The Orifice Flowmeter includes a thin Orifice plate, clamped into orifice flanges.
An orifice plate, which is the device to determine the motion of the inner fluid or gas, is protected in between 2 orifice flanges, which are connected to the pipeline. The orifice plate contains a little hole; with two pressure tap holes are drilled in each flange which assists in determining the pressure constructed inside the pipeline.
A 'jack screw' fitted between the two flanges, it makes it possible for to separate the flanges during assessment or replacement procedure.
Use:
Industries where Orifice flange is utilized -
Heavy and light chemicals
Steel
Paper
Nuclear
Petrochemicals
Sewage treatment
Water treatment and distribution
Power Generation
Oil production and refining
Gas Processing and transmission
Chemicals
Thus, these flanges play an important role throughout the maintenance period of the piping system. They are the best suitable for complicated pipeline networks.
