Get high-quality Carbon Steel Flanges at the best prices. Flanges are basic mechanical devices used to connect pipes, valves, pumps, and more. They are circular and usually welded or threaded with each other.

They come in two pieces, which are later joined by bolting with the gaskets. It helps the pipes to stay sealed and prohibit the leaking of material. The flanges are types of coupling up two lines.

The diameter and length of flanges depend upon the size of the pipes. There are various types of flanges available in the market namely Round Neck, Weld Neck Flanges, Socket Welded Flanges, Slip-On Flanges, etc.

What are the applications of flanges? 

  • Petrochemical industries

The flanges are used to connect pipes and valves. They are used to connect pipes with gaskets. This helps in the transfer of material used in petrochemical industries that have high pressure and temperature. It provides easy inspection of the material by eyes. They could be cleaned easily.

  • Automobile industry

They are used in vehicles to connect the engine and the transmission.

  • Electronics

They are used in many electronic devices to join various parts. For example, the flanges are used to connect the glass and the lens of the camera.

What are carbon steel flanges?

The cast carbon steel flanges or the CS flanges are one of the types of materials that are used to make flanges. CS FLANGES or Carbon Steel flanges are one of the types of flanges based on the material of manufacturing flanges.

The Various Types of CS FLANGES or Carbon Steel Flanges 

  • Weld Neck CS Flanges

Weld Neck CS Flanges have an outburst neck attached to the top of the flanges. They are also known as high hub flange or tapered hub flange. Such flanges are used to reduce the pressure of fluid in the bottom of the flange. They are used in high temperature as well as in low temperature withstanding the high pressure. They provide commendable stress distribution through the tapered hub, which helps the flanges to work more efficiently. They could handle pressure up to 5000PSI.

What are the applications of Weld Neck Flanges?

  • Oil and gas pipes
  • Vehicle rims:- car rims, motorcycle rims, chain rims,etc
  • Reinforcing of steel
  • Slip-On CS flanges

Slips on flanges are placed on the end of the pipe with a flange face extending from the end of the pipe by sufficient distance to apply a welded beard to the inner diameter. They are also known as “SO” flanges. The diameter and size of the slip-on flange are bigger than the pipe which helps it to slip over the pipe with internal design. The top and bottom of these flanges could be connected easily by welding them to the pipe. They are majorly used for low-pressure pipes and are considered to be suitable for fluid material.

What are the applications of slip on flanges?

  • Cooling water lines
  • Fire fighting water lines
  • Low-pressure air compressor
  • Threaded CS flanges

Threaded flanges are very similar to the slip-on flanges but the major difference is in the size the slip-on face flanges have a larger diameter than pipes whereas the threaded flanges have a diameter matching the pipes. They are used for pipes with high pressure and small diameters. the main benefit of threaded flanges is that they could be installed without welding.

What are the applications of threaded flanges?

  • Petrochemical industries
  • Chemical industries
  • Textile industries 
  • Reducing CS flanges

The reducing flanges are used when the pipe size is not the same they keep on changing.These flanges generally come in neck flanges that are blind, slip-on, threaded, and weld. They are available in all pressure classes and offer an excellent alternative to connecting two different pipe sizes. The reducing flanges consist of 2 bores one which has a fixed diameter and the other one with a smaller diameter.

What are the applications of reducing flanges?

  • Used for the pipe to pipe connections
  • Food processing industries
  • Paper and pulp industries
Weld neck flanges
  • Withstand to the high pressure of the material.
  • Suitable for both low-temperature and high-temperature fluids.
  • Good sealing
  • Bulky and expensive
Slip on flanges
  • Easy installation process
  • Cost-effective
  • Comes in a wide range of sizes and diameter
  • Not useful in the situation of high pressure and with hazardous fluids.



Threaded flanges
  • Could be installed without welding
  • Easy to be maintained
  • Convenient installation
  • Not recommended for very high temperature it may have leakages.
Reducing flanges
  • Wide ranges of pressure types and diameters.
  • Effective in connecting pipes with separate diameters.
  • They are not suitable for changes that could cause unnecessary turbulence


 What are the types of Carbon Steel flanges based on flange finish and facing types? 

  • Flat face flange (FF)

A flat face flange has a flat top and bottom unlike a few having ridge-like elevated or ring type joint flange. It has a gasket on the surface which allows full contact between the entire matting face. They are used in low-pressure and low-temperature surroundings.

What are the applications of flat face flanges?

  • Low-pressure water supply pipes
  • Filtration plant
  • Water treatment plants
  • Raised face flange(RF)

These are the most common flange face type used. It’s called a raised face because it has a raised surface above the bolting circle where the gasket is placed. Sealing this type of flange face is accomplished by compressing a soft, flat, or semi-metallic gasket between mating flanges in the raised area of the flanges. They are suitable for high as well as low temperatures. The flange diameter is directly related to the pressure that is higher the pressure larger the diameter.

What are the applications of raised face flanges?

  • Oil and gas pipelines
  • Chemical industries
  • Automobile industries
  • Male and female flanges(M & F)

Male and female flanges are the type that fits in one another. the male flanges stretch more than the usual flange face. The female flange has a depression in its nose which attaches with the male flange.

The female flange is supposed to belong whereas the male flange is supposed to be wide. Male and female flanges tend to have more sealing abilities and are more reliable for positioning.

What are the applications of male and female flanges?

  • Used in the piping of same material
  • Oil and gas pipelines
  • Plumbing
  • Ring joint flange(RJT)

The ring joint flange is used when metal to metal seal is required. They are highly used and suitable for high pressure and high-temperature operations. They could even function above 800 degrees Celsius.The ring joint flange features a circular groove to accommodate a ring joint gasket.

As the two ring joint flanges are bolted together and then tightened, the applied bolting force deforms the gaskets inside the flange the groove creates a very tight metal-to-metal seal.

What are the applications of ring joint flanges?

  • Furnaces
  • Petrochemical industries
  • Chemical industries
Weld neck flanges
  • Cost-effective
  • Lightweight
  • Not suitable for high pressure and temperature
Raised face flanges
  • Good sealing ability.
  • Suitable for both high as well as low temperatures.
  • They are expensive
Male and female flanges
  • Better sealing properties
  • Reliable
  • They are very expensive.
Ring joint flanges
  • Efficient in working with high pressure and temperature
  • The leaving of such flanges open may lead to the accumulation of dust and may disrupt the functioning.

What are the advantages of Carbon Steel flanges?

  • They are lightly weighted comparing to other hard metal flange types
  • Greatly affordable, they are a lot cheaper than other metals such as titan steel or stainless steel.
  • They are very malleable; they could be given a reshape or could be made in any shape or type easily.
  • They are very durable
  • They are good machinable alloy
  • What are the disadvantages of Carbon Steel flanges?
  • They are comparatively less strong and are not recommended for high pressure and high temperature.
