Stainless Steel Long Welding Neck Flange Supplier in Mumbai

LWN or as referred to as long weld neck flanges are most commonly seen in the oil and gas industry. The oil and gas industry uses high temperature and high pressure in their processing. And the materials being processed in these systems have different viscosity. Together all these parameters can stress out the components used in a piping system including flanges. Therefore, materials like stainless steel or other durable materials are preferred by Long Weld Neck Flange Manufacturers. Another benefit of using this device is that they function well despite fluctuations in temperatures.

Long Weld Neck Flange

Not many flange types can bear the fluctuation of temperatures, without failure. Fluctuation in temperature is very common in industries that deal with the processing of chemicals or even oil and gas. The design of the Ansi Ss Long Weld Neck Flange is what supports their use across such industries. Unlike a conventional weld neck flange, the construction of these flanges includes a long neck. The long neck here acts as a reinforcement, especially in critical piping systems that deal with safety. The reinforcement provided by the Carbon Steel Long Weld Neck Flange forms an integral part in the prevention of hazards in high pressure systems or in industrial and domestic applications. These flanges act as an anchor of sorts in places such as apartments or in factories. In processing factories or in apartments, the water-mains or gas pipe systems need Long Welding Neck Flanges as an anchor point. Therefore they arent welded to the pipe, the square cut on these flanges proves to be useful, especially since the Stainless Steel Long Weld Neck Flange may be used to replace the pipe in a system.

What Is A Long Weld Neck Flange

Long Weld Neck Flanges resemble weld neck flanges, aside from the neck, which is expanded and acts like an exhausting expansion. Long weld neck flanges can be utilized in high pressing factor modern applications, just as high temperature circumstances. They are frequently used in the oil and gas or petrochemical businesses.

Stainless Steel Long Neck Flange Weight Calculation

The weight of a long weld neck flange can be calculated by using the following formula :
Mass = [ ( X + B ) / 2 * ( X – B ) / 2 * 0.0246615 * ( Y – T ) * 10-3 ] + [ ( D2 – B2 – nd2 ) * T + ( G2 – B2 ) * t ] * 6.165375 * 10-6,
