Weld neck flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. Our range weld neck flanges, welding neck flanges are normally used for high-pressure, cold or hot temperature. We specialize these flanges in different dimensional and material specifications based upon the requirements of the clients.

Description:
API 6A Weld Neck Flanges� are pipe flanges� attach by welding the pipes to the neck of the flanges. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Welding neck flanges remove stress concentration and allow full working pressure and they� are often used for high pressure applications. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing.

RFP India offers a range of Weld Neck Flanges As the name implies it is called as a neck part of the flange which is being welded to the last points of the piping system Weld Neck Flanges has a wideranging tapering focal point and are commonly used for high pressure applications In fact it is being designed to shift the pressure within the pipe in a way to dip the high pressure concentration towards the bottom of the flange Weld Neck Flanges are also quite known from other forms by their wideranging pointed centre and modest development of thickness in the butt weld area by joining them with the pipe

Carbon Steel Forged Weld Neck Flange
A carbon steel weld neck flange is a type of flange used in piping systems. It is made from carbon steel, which is a common and widely used material in various industries due to its strength and durability. The weld neck flange is specifically designed to be butt-welded to the pipe, providing a strong and leak-proof connection.
Description
Carbon steel weld neck flange is made of carbon steel with a forging process, It consists of a circular fitting with a protruding rim around the circumference. These flanges are typically butt welded to a pipe, the rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
Design: A weld neck flange has a long tapered hub that is welded to the pipe, providing reinforcement and stability to the joint. The flange also has a flat, circular plate with bolt holes to connect it to another flange or equipment.
Welding: The flanges are designed to be welded to the pipe or fitting. The neck of the flange is welded to the pipe, creating a strong and leak-resistant connection.
Size Range: The flanges are available in a wide range of sizes to accommodate different pipe diameters and system requirements.
Applications: Carbon steel weld neck flanges are commonly used in industries such as oil and gas, petrochemical, power generation, and water treatment. They are suitable for high-temperature and high-pressure applications.
Advantages:
Provides excellent structural support and stability to the joint.
Reduces stress concentration at the base of the flange due to its tapered design.
Offers good resistance to corrosion and high temperatures when made from carbon steel.

Flanges used for steel pipeâ??s connection are various. So we should make our flanges lead to the purpose of our steel pipes like seamless or erw steel pipe. So we need to do some lesson before purchase.
Function of long weld neck flanges is predominantly on vessels. We know that vessels have some places need an extended neck so flange can do this job for us. The purpose of tapered neck is to reduce the thickness of the steel and it then seems to be a pipe extension. The combination of steel pipe and long weld neck flange would make the whole engineering project easy and convenient. Utilized in the chemical and petroleum industries, as well as commercial and residential buildings that experience high levels of stress and temperatures that fluctuate, flanges have played an important part during our daily life.
With regard to our wellheeled industrial experience RFP India offers a total range of Long Weld Neck Flanges We provide different types of Long Weld Neck Flanges such as Stainless Steel Long Neck Flanges Carbon Steel Long Neck Flanges Alloy Steel Long Neck Flanges Nickel Alloy Long Neck Flanges Copper Alloys Long Neck Flanges Low Temperature Carbon Steel Long Neck Flanges Duplex amp Super Duplex Steel Long Neck Flanges etc Comes in dissimilar grades sizes specifications and standards these neck flanges are being supplied from the mosttrustworthy vendors by our experts
Meanwhile these flanges are kind of exclusive for the reason of their uncomplicated connectivity with other pipes
