What is the pupose of flange fittings?
but what are flang fittings?what do they do?what are they made of?how expensive are they?what are cast iron flanged fittings?are they available in online shopes?there can be lots of questions about flange connection.you can find an answer to all these questions on the internet.Flanges are a type of coupling of pipes, valves and devices to each other. Flanges are disk-shaped, often coupled using two bolts, easily open and are suitable for low and high pressures.
Flanges are fittings that connect transmission pipelines (with any type of fluid), and also connect valves to welded pipes. Flanges are often made of polyethylene, steel, iron or cast iron alloys. The flanges are subdivided into different classes depending on the type of material, depending on the pressure they endure.
Are there plastic flange fittings on the market?
you may be wondering what is the difference between plastic flange fittings and brass flange fittings?another question is are plastic flange available on the markets?what are their functions?what is known about flange fitting breast pumps?how many flange types are there?Specifications of flanges
According to the standard, the flange specifications including the following must be engraved on the flange.
Flange manufacturer brand
- Nominal size of pipe (outer diameter of pipe where flange is welded).
- Tolerable pressure value (flange class)
- Shape of the flange surface (the most important part forming a flange).
- Holes (sometimes also referred to as wall thickness).
- Flange Ingredients (This number indicates the raw material used to make the flange according to ASTM standard).
- Number or code related to heat treatment on the flange
Pressure rating according to 16, 16SISI B: According to this standard steel and alloy flanges are classified into 150-300-400-600-900-1500-2500 grades. These numbers are the maximum pressure in terms of PSI that the flanges can withstand at the maximum allowable temperature.
ISO Classification of Pressure: This standard shows the bearing pressure of steel flanges and its alloys with PN, in which the nominal pressure is denoted in BAR.
Flanges are usually made of forged. Only in a few cases are sheets made. In the ASME 5,16B standard, only blind flanges and conversion flanges can be made of weldable quality sheets.
Durable types of flange fittings for sale
- when it comes to buying flang one ofe the most crucial factors can be durability.but what is the difference between durable flange fittings and the ordinary ones?how can we distinguish them from each other?how can the be classified?Types of flanges
- Flipper with simple sliding surface
In these flanges, the surface of the two flanges used should be smooth when coupling. Its main use is when we use two flanges for the system, or water connections made by casting. Usually cast iron or steel flanges that are used at low pressures are of this type. According to flange standards, when flanged surface flanges are attached to carbon steel flanges by metal molds, the flanged surface flanges must be removed.
- Male and female flanges
This flange must be made in pairs. The surface of one of the flanges has a protrusion and the other has a protrusion. Depending on the position used, the indentation and protrusion surface is designed with specific ratios, typically 3.16 inches deep and the material surface has 1.4 inches protrusion. The use of male and female flanges can be traced to the channel and flange cover in the heat exchanger shell.
- Welding neck flanges
The weld neck tube flanges are connected to the neck by welding. This enables the transfer of stress from the weld neck flange to the pipe and also reduces the high stress concentration at the base of the weld neck flange. Welding pipe flanges are often used for high pressure applications. The inner diameter of a welding neck tube flange is machined. The pipe’s inner diameter is machined to match the inner diameter of the pipe
- Blind flange
At the blind flange is a fully closed round plate used at the end of the piping and pressure paths. This type of flange and its screws bear more pressure than other flanges, which apply the most pressure to the middle of the bulletproof flange.
- Laptops Fluid
Laptops are often used for stub end connections. The tube is usually welded to the end of the stub, and the flange of the juvenile tube can rotate freely around the end of the stub. The advantage is that there will be no worry about adjusting the screw holes. Laptops flanges are often used for applications that require frequent arm closures.
- threaded flanges
Threaded flanges are similar to slip flanges, except that the inside of the flange has a conical thread. Threaded flanges are attached to the outer threaded tubes. The advantage of these flanges is that they can be attached without welding. Threaded flanges are often used for small diameters and low pressures.
How to choose best and high quality flange fittings?
it has always been a concern for customers to buy the best and most durable flange fittings.but how can they?how can they buy flange fittings with high quality?The flanges are functionally divided into the following categories:
- Simple Level (FLAT FACE)
In this type of surface one flange which must be opposite the surface of the other flange is flat. Typically cast iron or steel flanges that are used at low pressures are of this type.
Pumps are used for connecting valves and cast iron fittings and non-steel flanges. It is also used for low pressure lines such as (Cooling water-CWR-CWS) where leakage is not important. Joints are also used to seal the joints with an outer diameter equal to the outer diameter of the flange. This also makes it impossible for the two parts to be joined, resulting in reduced fracture potential.
- Raised face flange
In this type, the flange surface, which is facing the other flange, is made more prominent than the overall surface. According to the standard, the amount of bumps in all sizes for grades 1 and 2 is 2.5 mm and for higher grades is 1.5 mm. The bumps may have a smooth finish or a serrated finish and these slots are either concentric or spiral whose construction is specified in the standard (mss-sp-1) (usually deep grooves). 1.5 mm and its distance is 2.5 mm)
- Male & Female Flange (Male & Female)
Plates of this type exist in pairs, one with a protrusion (at a height of 1.5 mm) and the other with an indentation (at a depth of 1 mm).
- Tongue & Groove Facing Plate Flange
This type also exists in pairs and is similar to the male and female flanges except that the inner diameter of the tongue and groove does not extend to the flange hole (flow path) and thus holds the gasket on its inner and outer diameters. It causes the gasket to remain protected from corrosion. The tongue and groove structure requires a minimum flat surface, and therefore under the pressure of screws will have the lowest load and maximum joint efficiency possible for flat layers. In this type of connector, the tab protrusion rate is 0.9mm and the groove depth is 0.8mm.
What are different types of flanges?
but what about different types of flanges?what is known about flange pipe?Benefits of socket welding flangeThis tube does not require furnace welding preparation.There is no need to move the temporary position in time, as the principle of coordination guarantees proper coordination.The weld metal cannot penetrate the hole in the pipe.They can be used in place of string connections, so the risk of leakage is much smaller.Radiography does not apply to Philips welding, so proper welding and welding are important. Filter welding can be investigated by surface inspection, magnetic powder (MP) or liquid penetration inspection (PT). Due to the need for careful assembly and elimination of the assembly end of special processing joints, the construction cost is lower than the welding head.
Main Features of Socket Welding FlangeThe groove in the inner diameter allows convenient fit of pipe, allowing for smooth flow of fluid suitable for small sizes and high temperature pressure conditions.Similar to sliding flange, but pipe arrangements should be used for socket welding. The figure below shows the inner diameter of the socket welding flange. This flange happens to be the so-called insert flange. This is a two-piece flange that allows rotation of the outer flange, easy to twist the hole. SFF can provide these flanges and all-in-one standard welding sockets.

Iron alloy is an alloy that is commonly referred to as an iron flange and in fact iron flanges have an iron element base and their alloy is steel and is known in the market as iron or steel flanges. .
Welding flanges provide easy access to cleaning, inspection and repairs and are connected to the pipe using welding. The flange connection is created by screwing two flanges together and a gasket to seal between flanges. Throat weld flange, SLIP ON flange, soft weld flange, blind flange are common types of weld flanges.
Welding Neck Flange
The welded flange holds high pressure and force and is useful when the system is under alternating forces and strengthens the flange connection to the pipe.
Slip on welding flange
This type of flange has no throat and is used for low pressure lines and has low resistance to vibration and vibration of the system.
Socket Weld Flange
Silent valve flange is used for high pressure lines. In this type of flange, the tube head is of a flat type, which is inserted into the flange socket and welded around it.
Used to temporarily block the route.

What is a flange connection?
– One of the types of pre-accepted clamp connections is the flange clamp connection. In this post we will get more familiar with this connection. The flange is the end plate of the welded beam that is perforated and its height is greater than the height of the beam. In this connection two pieces are connected by flange In this type of connection, the wings and beams are first welded together by a sheet and then bonded to the column wings by screwing the sheet.
