What are the Main Types of Flanges?

STANDARD FLANGES

SLIP-ON FLANGE

The flange is slipped over the pipe & is settled by welding at both top & base side of the flange. They are used to provide high strength to the connection & prevent leakage. This flange is used more over weld neck flanges as less accuracy is needed while cutting pipe to length, the cost of making is lower but there is nearly the outcome is same. To know more about Slip on Flanges visit flanges manufacturer in Oman.

BLIND FLANGES

Blind Flange is a flange without a bore and it is also called a blanking flange, which is used to fix or seal an end of a piping framework or closing a piping system or vessel opening. Inspection of vessels or piping system is easier & it is simpler to access it.

LAP-JOINT FLANGES

This is flange similar to a slip-on flange, but it has a radius at the intersection of the bore & the flange face to acquire a lap stub end. This type of flanges is used in applications where section of piping systems needs to be dismantled quickly & easily for replacement.

SOCKET WELD FLANGES

This flange is similar to a slip-on flange, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is same to inside diameter of the pipe. An optional interval weld can be applied in high pressure applications. To know more about socket weld flanges, visit flanges supplier in Oman.

THREADED FLANGES

In this flange the bore is threaded, thus enabling assembly without welding. This is limited to its application to relatively low-pressure piping systems. The flange can be welded around the joint after assembly, but this is not considered a good method of increasing its applications.

WELD-NECK FLANGES

As its name, this is a flange attached by welding neck of flange to a pipe. It is expensive because of its long neck, but it is more suitable for high pressure Machines because the neck gives important reinforcement to the flange. The bore of the flange matches the bore of the pipe, reducing turbulence & erosion.

SPECIAL FLANGES

GROOVE FLANGES / TONGUE FLANGES

A groove flange is mainly paired with a tongue flange. One flange has a machined raised ring & the other one has machined groove depression. Those 2 flanges must match perfectly with each other. To know more about tongue flange visit flanges exporter in Oman.

LONG NECK FLANGES

Owing to our good experience in the industry, we are offering a comprehensive range of Long Weld Neck Flanges. The experts of our organization source these neck flanges from trusted vendors. These flanges are different because of their simple connectivity with other pipes.

ORIFICE FLANGES

The role of an orifice flange is to give access to a line for metering of gases or liquids. An orifice plate is clamped between a pair of flanges while installing it in a line. Jack-screws within the assembly gives smoother removal of the orifice plate.

SPECTACLE FLANGES

This is a pressure retaining plate with one solid end & one open end connected with a web or tie-bar. In normal operation, the open end forms the seal between two flanges & permits normal flow of fluid through pipe work. If the solid end is swung into position it effectively blanks of the pipe & halts the flow.

Flanges used for Oil and Gas Industry

· Weld neck

A welding neck flange (“WN”) is a long-tapered hub which can be welded with a pipe. This flange type is used, normally, in dynamic-pressure & high/low temperatures applications that require an unrestricted flow of the fluid conveyed by the piping system (the bore of the flange matches with the bore of the pipe). To know more about other flanges, visit stainless steel carbon steel flanges manufacturer in Saudi Arabia.

· Slip on

A slip-on flange is connected to the pipe or the fittings with the help of two fillet welds, one executed inside & one outside the cavity of the flange. The bore size of a slip-on flange is gigger than the outter diameter of the connecting pipe, as the pipe has to slide inside the flange to be connected by the execution of a fillet weld.

· Lap joint

Lap joint flanges feature a flat face & are always used in conjunction with a stub end. Lap joint flanges appear likes, in shape, slip-on flanges except for the radius at the crossing of the flange face & the bore to accommodate the flanged portion of the stub end. If you are searching for exporter, you can find leading stainless steel carbon steel flanges exporter in Saudi Arabia

· Threaded

Threaded flanges are connected to pipes by screwing the pipe (which has a male thread, generally NPT per ASME B1.20.1) onto the flange, without seam welds (in certain cases, though, small welds are applied to increase the strength of the connection).

· Blind

Contrary to all the different types of flanges seen above, blind flanges do not have a center hole, & are used to blind or seal a pipeline, a valve/pressure vessel & block the flow of the fluid. Blind flanges have to withstand remarkable mechanical stress due to the system pressure & the required bolting forces.

5 Advantages of Flanges

Though there are some specific uses where flanges & flange fittings are the only practical choice (particularly in larger, high pressure piping applications), flanges also provide benefits to the piping system that traditional hydraulic fittings don’t. For instance, in those larger OD applications flanges are easy to be connected to pipe (tube or hose) & component ports more easily than threaded fittings or adapters. To know more advantages of flanges, visit Pipe Fitting Flange Manufacturers in Hyderabad. Most importantly, in service applications on mobile construction equipment flanged connections are best for:

Ease of assembly in tight spaces where wrenches might not have clearance if installing traditional fittings, & they are more easily assembled with moderate torque.
Difficult to reach areas where flexibility is required, eliminating the need for adapters in the tube, pipe or hose line.
Big hose, tube or pipe fittings where shock, vibration, high pressure &/or pressure surges are present, which can easily damage a traditional large hydraulic fitting.
Making connections that allow for easy maintenance in rigid lines such as continuous pipes or metal tubes.
Reducing the chance of components becoming loose in rigorous hydraulic applications.

Using flange connections in these big size, high pressure circumstances allows for easier assembly over using huge fittings. The flange’s zero-clearance assembly, ease of disconnecting & reconnecting for maintenance of hose, tube & manifold connections, can be much faster & provide the ability for more accurate torque of the bolts as opposed to trying to achieve the proper torque of big fittings. Flange & flange fitting connections are very less likely to choosen compared to a standard hydraulic fitting when there is proper load distribution of clamping around the flange head. If you do not tighten the lug nuts in a star pattern then the wheel will not tighten evenly, which may lead to warping of the brake disc, rotor or brake drum. Flange connections are also the best option for hose end connections that have bends & are subjected to very high lateral forces that are inclined to cause loosening of the assembly. There are leading Pipe Fitting Flange Exporter in Hyderabad.

Types of Pipe Fittings in Plumbing System

Elbow Pipe Fittings

Elbows are used to change the direction of flow between 2 pipes. Elbows are generally available with different angle of 22.5o, 45o & 90o. If the diameter of the pipe is same then normal elbows are used otherwise Reducer elbow is used. Elbows are made of different materials. These are generally coming with female threads & we can fix them by butt or socket welding also. Click here to know more about pipe fitting manufacturers in Mumbai.

Reducer Pipe Fittings

Reducer is a pipe fitting component which decreases the flow size from larger to smaller by reducing the size of the pipe. Usually, there are 2 varieties of reducers are available. One is concentric reducer which is similar to cone-shaped with slowly decreasing around the pipe but in this case, accumulation of air may possible & it results in cavitation. Another one is eccentric reducer which is having 1 edge parallel to connecting pipe due to which air accumulation is not possible.

Tee type Pipe Fitting

Tee type fitting is a component of a pipe fitting system which is in T-shape. It is having one inlet & two outlets, outlets are arranged at 90o to the mainline connection (inlet). It is also used to combine the flow from 2 inlets to 1 outlet. They are also available in different variety of materials & different sizes. If the three sides of T-fitting are of the same size then it is called as Equal tee otherwise it is called Unequal tee. Click here to know more about pipe fitting manufacturers in Chennai.

Cross type

Cross-type fittings contain four openings in four directions. These are connected when there are four pipes are meeting at a point. These pipe fittings generate a huge amount of pressure on the pipe as the temperature changes because they are located at the center of 4 connection points. Cross fittings are generally used in fire sprinkler systems.

Unions

The union is a type of fitting, whose functions are similar to coupling. But coupling cannot be removed after fixing it once, but in this case, one can remove the union whenever we needed. Unions consists of nut, male & female-ended threads. Click here to know more about pipe fitting manufacturers in Bengaluru.

Different applications of Stainless Steel Pipes

Stainless steel is the world’s most flexible material which now has become indispensable part in a different type of industries. It is consisting of a steel alloy & little of chromium.

Benefits of Stainless Steel Pipes

When contractors select materials for metal pipework, stainless steel is often overlooked due to its price compared to other options such as PVC for applications such as wastewater & chemical transport. But the many advantages of stainless steel pipe for industrial & commercial application make this a material that provides value & return on investment.

1. Stain & corrosion resistant – Corrosion is the main enemy of metal piping. The outer surface of steel, iron & concrete piping can degrade from soil & UV light. Interior walls of piping made from other materials will tend to rust, are damaged through abrasion, or accumulate debris. But due to the corrosion resistance propertie of stainless steel, this is less common. This gives stainless steel the edge when it comes to products like sanitary water delivery or hospital applications. Click here to know more about pipes and tube manufacturers in India.

2. Value – When you buy stainless steel pipes, you are purchasing a durable product that will last your business for decades. Stainless steel is low-maintenance, & due to its corrosion-resistant properties, it is unlikely they will need to be replaced for decades.

3. Strength & versatility – Different materials such as nickel, molybdenum, or nitrogen can be added to stainless steel to enhance its corrosion-resistant properties. Stainless steel can handle high temperatures. By adding different materials to stainless steel allows for thinner pipe walls & less material which means less weight is added to the finished product making it ideal for all commercial & industrial uses. To know more about stainless pipe visit stainless steel pipe manufacturers in India.

4. Appearance – Exposed stainless steel pipe & fittings are an excellent choice for commercial establishments as the material has a naturally shiny & elegant look.

5. Environment-friendly – Stainless steel is not a petroleum product. In fact, there is no need of any coat over eat or lined with any materials at all, unlike other piping materials. When you need to replace or dispose of stainless steel piping, it is 100% recyclable, reducing the environmental impact. As much as 50% of all new stainless steel that is produced in the United States is made from recycled scrap metal.

Applications of Stainless Steel Flanges

Flanges are very important parts of many engineering & plumbing projects. Used in many, different industries, such as the transport (pipelines, ships) of petroleum, gas, water, etc., their manufacturing facilities & those of power generation, chemicals, & chemical fertilizers, flanges are of different type & grades, & their material too is diversified (low carbon steel, low alloy steel, stainless steel, high alloy steel, non-ferrous steel, or such) in accordance with the type of fluid & service environment. To know more about flanges, visit stainless steel flanges manufacturers in India.

In different applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the material inside must differ from the material outside in composition or pressure. They do this by fastening 2 pieces of metal or other material together with a circle of bolts on a lip. This “lip” is a flange.

You can connect 2 sections of metal piping by welding them together, but pipes connected in this way are very open to bursting at high pressures. A way of connecting 2 sections of pipe more securely is by having flanged ends that you can connect with bolts. This way, even if gases or liquids build up to high pressures inside the pipe, it will often hold it without any problem. Get here to know more about stainless steel flanges suppliers in India.

MECHANICS

In order to connect 2 sections of a large, enclosed area, it is often best to used flanges & fasteners (bolts). An example of this is the connection between the engine & the transmission in an automobile. In such case, both the engine & the transmission contain a number of moving parts that can easily get damaged if they get dust or other small objects inside of them. By connecting the outer casings of the engine & transmission in this way, engineers protect the inner workings of both.

ELECTRONICS

Flanges have a specific purpose in cameras & other electronic devices. Though flanges in such items do not usually have to sustain high pressures, they do have to hold tight so they can keep out harmful particles. These flanges are usually found connecting 2 different materials, such as the glass of a lens & the rest of the body of the camera.

Introduction to Slip on Flanges

Slip On flanges or SO flanges are generally lower in price than weld-neck flanges, & to this effect are a popular choice for the customers. It is welded both inside & out to provide enough strength & prevent leakage. As made obvious by their name, this flange slip over the pipe. There are many stainless steel slip on flanges dealers in India. These flanges are manufactured with an inside diameter that is little bigger than the pipe’s outside diameter. These attachments are connected to the pipe through fillet weld at the top & bottom of the flange.

However, customers should keep in mind that this initial cost saving may be diminished by the additional cost of the 2 fillet welds required for proper installation. But, weld-neck flanges have a greater life expectancy than slip-on flanges under duress. India is one of the leading stainless steel slip on flanges suppliers worldwide.

Slip-on flanges are all bored slightly bigger than the O.D. of the pipe. These flanges are preferred over welding neck flanges but many uses due to their lower cost, but final installation cost is probably not much less than that of the welding neck flange because additional welding is required.

Advantages of slip on flanges:

Low cost installation
Less time required to spend on ensuring the accuracy of the cut pipe
They are somewhat easier to align
The slip-on flanges have low hub because the pipe slips into the flange before welding
The flange is welded both inside & outside to give enough strength
They prevent leakage

Standards, Dimensions & Weight

Slip-on flange is slipped over the pipe & then fillet welded. Slip-on flanges are simple to use in fabricated applications.
