Carbon steel flanges are used for applications that require high strength and durability. These flanges are generally cheaper than stainless steel flanges and can be used in different environments without any issues.  Carbon steel flanges are manufactured by adding carbon to iron, which makes the steel much stronger and harder than pure iron. They have a wide range of applications due to their properties like high tensile strength, corrosion resistance, and finishing. Carbon steel flanges are used across some industries because they are so versatile. Farming, electricity, biochemical, petroleum, and other industries are examples.

Carbon Steel Flanges are an integral part of many piping systems. They’re attached to valves, pumps, and pipes. There are several different types of flanges, including welded, lap joint, blind, and many others.

Flanges are a type of mechanical component that can be used for power transmission or to connect two different machine parts. Flanges are generally made out of iron, and they come in a variety of shapes, such as those that resemble T-beams, I-beams, and screws.

NSEC is a specialised manufacturer of high quality ASME/ANSI/DIN standard slip-on flanges in India. We offer immediate delivery programs for standard size of carbon steel slip-on flanges and stainless steel slip-on flanges. Slip-on flanges manufactured in special stainless steel grades, nickel alloy and alloy steel can be supplied with just in time programs.

Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the slip-on flange to slip over the pipe. Slip-on pipe flanges are welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on pipe flanges can sometimes also have a boss/ring or hub, and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on pipe flanges because they both slip over the pipe.

Slip-on flanges are generally preferred by users over weld neck flanges, as they are a cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length.

Slip-on flanges are available with raised, flat or RTJ faces, and are also available in orifice configurations.

We offer slip-on pipe flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.

Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.

What are ANSI B16.5 Forged Flanges?

ANSI B16.5 Forged Flanges are a type of flange that is commonly used in high-pressure piping systems. These flanges are designed to be welded or bolted onto the end of a pipe and are typically made from forged steel. They are available in various sizes, pressure ratings & materials and connect pipes, valves, and other equipment in a piping system.

What are the advantages of using ANSI B16.5 Forged Flanges?

ANSI B16.5 Forged Flanges have several advantages, including high durability, resistance to corrosion and erosion, excellent performance under high-pressure and high-temperature environments, ease of installation and maintenance & availability in various sizes and materials to meet specific application requirements.

How are ANSI B16.5 Forged Flanges installed in piping systems?

ANSI B16.5 Forged Flanges are typically installed by bolting them to the piping system using bolts, nuts & gaskets. The flanges are aligned, and the bolts are tightened to create a secure, leak-proof joint. The installation process may vary depending on the specific type of flange and piping system being used. It is important to follow proper installation procedures to ensure the flanges are properly aligned and tightened for optimal performance.

The calculated strength of a Slip On flange under internal pressure is of the order of ⅔ that of a Weld Neck flange. While their life span under fatigue tends to be about one-third that of a weld neck flange. The connection between the flange and the pipe is done with 2 fillet welds. Which means the ASME B16.5 Slip On Flange is welded both on the inside as well at the outside. This space is necessary in the flange, to prevent the flange face from getting damaged during the welding process. ANSI B16.5 Stainless Steel Slip On Flange is essentially a ring that has been placed over the pipe end, with the flange face being extending from the end of the pipe by enough distance such that application of a weld bead on the inside diameter is possible.

Nickel Alloy Flanges is easy to operate, sturdy construction, durable and long lasting. We made these superior quality materials, which are easily applied in any kinds of uses or machinery. Our products are available in various sizes, shapes and design as per the requirements. Our clients can avail from us at reasonable prices.

Spectacle Blinds are used in separating pipe systems for the connection. It is a steel plate divided into two discs of a certain thickness. Out of these two discs, one disc is of a solid plate and other is a ring whose inner diameter is equal to that of a flange. Spectacle Blinds is required in the systems that regularly need to be separated from other installations. Generally, it is mounted in the “Open” position so that flow through the pipe is possible. If it is placed in the “close” position and if it is rotated, then, the pipe is blanked off and no flow is feasible. The whole idea of a spectacle blind is to ensure that an item of equipment is properly and securely blanked off with no leakage or no flow through a valve during maintenance.

The whole idea of a spectacle blind is so that one can be absolutely sure that an item of equipment is properly and securely blanked off with no possibility of any flow or leakage through a valve during maintenance. The flow can be diverted to other items of equipment but not just bypassed around the blank as this would compromise the safety function of the spectacle blind. The flow has to valved off and pressure relieved prior to loosening flange bolts and swinging the blind.

The ASTM A105 specifies different types of flanges, which can include various grades of stainless steel material. The ASTM A105 Carbon Steel Blind Flanges are made of forged carbon steel and are ideal for high-temperature applications. We are one of the top ASTM A105 CS BLRF Flanges producers in India, capable of meeting our client’s requirements. We produce different types of carbon flanges to meet the all-around needs of various industries. Some of the standard ASTM A105 Flanges we manufacture would include:

• ASME SA 105 Spectacle Blind Flange- is a steel plate cut into two discs of a given thickness. Here, one of the disks is a solid plate, and the other one is a ring, whose diameter is the same as that of a flange.


• ASME SA 105 Tapped Blind Flange- These test flanges are made of bling flanges having tapped NPT threaded holes in the middle. These are used at the end of a piping system and can withstand a great amount of pressure.


• SA105N Slip Blind Flange- We are one of the top stockists and suppliers of slip blind flanges used when the piping system needs maintenance, modification, removal, or inspection.


• Carbon Steel Paddle Blind Flange- It has a similar solid end as a spectacle blind wherein an additional handle is welded.


• A105 Low Carbon Steel Raised Face Blind Flange- helps to concentrate larger force on a smaller area, enhancing the containment capabilities.
