Flanges

Flanges are an essential component in the construction of piping systems. As such, they are used in a wide range of industries, from automotive to oil and gas production. India is one of the leading manufacturers of flanges in the world, providing quality products for various applications. In this article, we discuss the various types of flanges manufactured in India and their uses. We also look at the major manufacturers of flanges in India and their competitive advantage. Finally, we examine the trends for flange manufacturing in India and how it impacts the industry.

Flanges manufactured in India come in various materials, shapes, and sizes. Carbon steel, stainless steel, alloy steel, and super alloys are some of the most commonly used materials for flange production in India. Each material has its own unique properties that make it suitable for certain applications. For instance, carbon steel is highly resistant to corrosion and abrasion, making it ideal for use in piping systems that are exposed to harsh environments.

In addition to the materials used, flanges in India also differ in their shape and size. Flanges can be flat, circular or threaded, depending on the application for which they are required. The various sizes of flanges include Class 150, Class 300, Class 600 and Class 900. These classes refer to the maximum pressure rating of the flange, with Class 150 being the lowest and Class 900 being the highest.

Welding neck flanges, also known as high-hub and tapered hub flanges, are machined from forging and welded to the pipe. These pieces of metal have a protrusive rim around the circle, which is drilled with a series of holes that allow the flange to be bolted to another flange. The primary function of these welding neck flanges is to transfer stress to the pipe in order to reduce large stress concentrations at the base of the flange. Furthermore, using a welding neck flange can help prevent plastic deformation that can be caused by faulty welds or lack of material strength.

Welding neck flanges are specially designed with both pressure and performance considerations in mind, making them ideal for connecting pipes in high-pressure conditions. They come in a variety of materials including stainless steel, carbon steel, and duplex steel – offering an extensive range of corrosion resistance options depending on need. Additionally, these flanges’ elevated sealing surfaces can often help eliminate leak path deflection issues found within other types of lower raised face designs. Hence an array advantages make this type of flange one of the most popular on high-pressure systems everywhere.

Types of Flanges We Provide.

At Npro Engineers India, we specialize in providing a wide variety of high quality flanges for various industrial applications. Our extensive catalog of products includes slip-on flanges, weld neck flanges, orifice flanges, socket weld flanges and lap joint flanges. Each of these types of flange offers its own unique advantages to ensure optimal performance when incorporated into any piping system.

Slip-on Flanges

One of the most commonly used types of pipe fittings due to their simple installation and reusability. These pieces can be easily slipped onto the end of a pipe without welding or other fastening methods required. This makes them an ideal solution for connecting pipelines that may require frequent changes or repairs in the future .

Weld neck flanges

It provides the highest level of pressure resistance compared to other types of pipe fittings. These pieces are machined from forging and welded to the pipe, making them extremely strong and reliable for even the most demanding applications. Additionally, their elevated sealing surfaces can often help eliminate leak path deflection issues found within other types of lower raised face designs.

Orifice Flanges

They are designed specifically for use in measuring flow rate in a piping system. They feature an opening in the center that allows a device such as an orifice plate to be inserted into it, allowing engineers to accurately measure flow rates without having to install additional equipment into a pipeline.

Socket Weld Flanges

are used when space constraints do not allow for the use of a standard slip-on or weld neck flange. These pieces are much more compact and require less space when installed, making them ideal for tight installations. Additionally, these pieces can be easily assembled and disassembled, allowing them to be used in applications that may require frequent changes or repairs in the future.

Lap Joint Flanges

Designed to be used with “stub ends” which feature male threads that can be screwed into a female threaded pipe. The outer edge of the flange is machined to match the shape of the stub end, allowing them to form a tight seal when pressure is applied. This makes lap joint flanges an ideal solution for applications where frequent assembly/disassembly may be required.

Here are the Applications of Flanges.

Flanges are widely used in various industries for connecting pipes, valves, pumps, and other equipment. The primary purpose of flanges is to provide a secure and leak-proof connection between two or more components. Here are some of the applications of flanges:

Pipeline systems: Flanges are commonly used in pipeline systems to connect pipes of different sizes or materials. They are used to connect sections of pipes, valves, pumps, and other equipment.
Oil and gas industry: Flanges are extensively used in the oil and gas industry for connecting pipelines, pumps, and valves. They are used in offshore drilling platforms, refineries, and petrochemical plants.
Chemical industry: Flanges are used in the chemical industry to connect pipes and other equipment. They are used in processing plants for chemicals, acids, and other corrosive substances.
Food and beverage industry: Flanges are used in the food and beverage industry for connecting pipes and other equipment. They are used in dairy processing plants, breweries, and beverage production facilities.
HVAC systems: Flanges are used in HVAC (heating, ventilation, and air conditioning) systems to connect ducts, pipes, and other components. They are used in commercial and industrial buildings, as well as in residential homes.
Power generation industry: Flanges are used in power generation plants to connect pipes, valves, and other equipment. They are used in thermal power plants, nuclear power plants, and renewable energy facilities.

Overall, flanges are essential components in many industries and applications, providing a safe and reliable connection between different components.
