Ss Flanges Manufacturer In India

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 stainless steel flanges?

Stainless steel flanges or SS flanges are one of the types of materials that are used to make flanges. SS FLANGES or Stainless Steel flanges are one of the types of flanges based on the material of manufacturing flanges.

 

The Various Types of SS FLANGES or stainless Steel Flanges 

• Weld Neck SS Flanges

Weld Neck SS Flanges have an outburst neck attached to the top of the flanges. They are also known as high hub flanges or tapered hub flanges. Such flanges are used to reduce the pressure of fluid in the bottom of the flange. They are used in high temperatures as well as in low temperatures 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 steel

 

• Slip-On SS flanges

Slips on flanges are placed on the end of the pipe with a flange face extending from the end of the pipe by a 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
• Firefighting water lines
• Low-pressure air compressor

 

• Threaded SS 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 SS 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 welded. 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

Name	Advantages	disadvantages
Weld neck flanges	withstand 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 temperatures 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 stainless 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 flanges. 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 to 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 the 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

Name	Advantages	Disadvantages
Weld neck flanges	Cost-effective Lightweight	Not suitable for high pressure and temperature raised
Raised face flanges	Good sealing ability. Suitable for both high as well as low temperatures.	Thexpensive maleive
Male and female flanges	Better sealing properties Reliable	They are very exp ensive.
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.
