What is the priciple of orifice flow meter?
An orifice flow meter is one of the simplest forms of flow meters. It is just a flat piece of metal installed in a pipe between flanges with a specific sized hole bored in the middle used to create pressure that can be detected by pressure taps on either side of the plate.
What is integral orifice instrument?
For pipe size <1/2",and clean fluid service,it is common to use orifice installed integrally with the differential pressure Transmitter.It provides compact installation and the overall accuracy is pre-determined.
Different Types of Flanges Used in Piping Applications?
Flanges are piping equipment that is used to connect different pipes and valves. Flanges are attached to the end of a pipe, where another pipe is to be attached. Flanges are used to create a piping system, where they are used to change direction or connect two different valves or pipes.The Flange types are classified on the basis of application and grade of metal used for the production of Flange Face. Each type of flanges has a different purpose than the other. Here are various types of flanges,Types of Flanges: -1. Threaded Flanges: - The Threaded flanges have threads under their bore. They are also known as Screwed Flanges. The Thread is used to fix the pipes, which also have threading on their end. They are the easiest to fit Flanges but are not suitable for high-temperature applications. They are also not suggested for high-pressure applications.2. Slip-on Flanges: - Slip-on Flanges are made with holes that match the outer diameter of a pipe. The pipe is passed through the hole and fillet welded from both sides. Low pressure and low-temperature applications are suitable for this kind of flange joint. Slip-on flanges are generally forged and come with a hub. Large sizes are used to connect big bore pipes with storage tanks.3. Socket-Weld Flanges: -Usually used only for Low pressure and temperature applications, Socket-Weld Flanges have a female socket. A pipe is fitted through the female socket in the Flange.4. Lap-Joint Flanges: -Lap-joint flanges are made in two components, which include a stub-end and a loose backing flange. Lap-joint Flange is used for applications that require frequent dismantling. They are designed to not wear from frequent modifications.5. Blind-Flanges: - These Flanges are used as a termination point to a piping system. Blind-Flanges have a blank surface with a bolt point to fit a pipe.6. Spectacle blind flanges: Spectacle Blinds, generally referred to as SB, are Flanges that are applied to systems that require regular separation from their installation. Spectacle blinds are made from two discs, that are attached to each other. One of the discs in SB Flanges is a ring and the other is a solid plate.7. Long weld neck flanges: Long Neck Welding Flanges are made with a circular fitting and a bulging rim around the circumference. They are similar to standard Welding Neck flanges but with a particularly long neck. They are generally not used for pipes but in processing plants.8. Orifice Flange: Orifice Flanges are used to measure the flow rate of liquids or gases in the pipeline. They are used with orifice meters and are suitable for all intensive weld neck flanges with extra machining.9. The Flat-Face flange: Flat Face Flanges frequently are used where casting is used to make mating flange or flanged fitting. Similar to a bolting circle face, they have a gasket surface in the same plane.10. Ring Type Joint: The ring Type Joint flange, generally known as RTJ, is made by putting some grooves cut on their faces. They seal when the Bolts are tightened. These bolts compress the gasket into the grooves. These Flanges are typically used for high pressure and high-temperature services.11. Raised Face: The Raised Face Flanges are high-pressure flanges that have a raised face due to gasket surfaces are raised above the bolting circle face. They are widely used in process plant applications because of their increased pressure containment capability.12. Tongue & Groove: The Touch and groove Flanges consist of two flanges, where one face consists a ring machined onto the flange and the other contains a depression matching the ring on the other. These are commonly found on pump covers and Valve Bonnets.
Are flanges designated by schedule?
If your talking pipe flanges, they are designed by pressure at certain temps. 150lb is standard, and 300lb is for steam applications.
How pipe flanges are electrically insulated?
Pipe flanges are protected from corrosion by means of electrolysis,with dielectric flanges. The piping system is electricaly insulated by what is called a sacrificial anode. A bag of readily corrodable metal is buried in the ground with a wire running from the pipe to the bag so that the sacrificial anode will corrode first. If any electrical current charges the pipe it also serves as a ground.
How can flanges be classified based on pipe attachment?
Flange joint is one of the methods of pipe joints. Piping and flanges are classified in different ways based on pipe attachment, Pressure-Temperature (PT) rating, facing, face finish. Below are the flanges based on the pipe attachments.Classification of flanges based on pipe attachment1) Slip-on Flanges:These flanges are welded on inside as well as outside to the pipe. They are generally forged type with Hub. They can also be fabricated from plates but without Hub.2) Socket-Weld Flanges:These Flanges are welded only on outside of the Pipe. They are usually used in small bore piping where the piping specification is socket weld. They are not used in severe services due to stagnation of fluid at the socket. Socket welded flanges shall be specified with connection pipe thickness to ensure proper bore dimensions.3) Screwed/Threaded Flanges:These Flanged are screwed onto outside diameter of the Pipe. They are used at locations where welding is not allowed. They are used in temperature range of 250 Deg to -45 Deg. The threads can be NPT (Nominal Pipe Threads) or BSPT (British Standard Pipe Threads) as required in the Piping specification.
Where is orifice tube located in a 2003 jeep wrangler?
The orifice is located in the low side hard pipe at the condenser outlet. This is the hard pipe which goes from the condenser to the evaporator with the low side port.
Does the toilet flange go on the inside or outside of soil pipe?
Toilet flanges OUTSIDE of the pipe including cast iron and brass to lead
What is a pipe spool?
A pipe spool refers to a prefabricated section of a piping system. This includes the pipe, fittings and flanges that are pre-assembled. They are pre assembled because this can be done in a controlled environment.
What is the working principle of orifice meter?
An obstruction (orifice) is placed in a pipe filled with fluid. The pressure of the fluid is measured at two different points: 1) just upstream of the orifice and, 2) close to the contraction of the fluid (vena contracta). The difference in these two pressures is known as differential pressure. The differential pressure across an obstruction (orifice) in a pipe of fluid is proportional to the square of the velocity of the fluid. Many factors associated with the pipe, orifice and fluid affect the measurement. Satisfactory measurement requires steady-state, homogeneous, turbulent flowing fluids. Other properties which affect the measurement include: the ratio of pipe diameter to orifice diameter and the density, temperature, compressibility and viscosity of the fluid.
What is the basic definition of a pipe flange What exactly is the role it plays in a pipe assembly?
A pipe flange is used in the assembly of pipe to pipe or other things like valves, elbows etc. The flanges are bolted together, creating several lengths of pipe or other assemblies.
Where is the orifice tube on a 1998 ford escort?
If you're talking about the orifice tube for the A/C system, it is in the hard pipe A/C line (under the hood) that runs across the firewall. turns and runs to the condenser. So with the hood open, it would be on your right, close to the electrical relay box, at the connection point in the hard pipe. The pipe has an expanded diameter right where the orifice fits in. They are usually very difficult to remove. There is an expensive tool you can buy to help remove it. There is also a kit sold that permits you to cut the tubing behind the orifice and splice ina new section of pipe with a new orifice tube in it. I've done that before with no problems.
