Stainless long weld neck flange is commonly found in Multi-level buildings. These specialized connections are also used in other industries including power generation, petrochemical, and refineries. DINESH INDUSTRIES manufactures specialized and standard connection types and long weld neck flange components.

ANSI long weld neck flanges are built in a variety of lengths according to need. The flange is normally beveled so it can be butt-welded to pipe, adding extra strength. Pipes provide better flows with this type of connection forging.

The piping systems of high buildings are safer when reinforced with long weld neck flange standard that relieve pressure in the pipes. This same style of flange helps balance the constant changes in pressure and temperature of liquids flowing in gasoline and chemical pipelines.

The American Society of Mechanical Engineers (ASME) sets manufacturing standards for raised face long weld neck flange shape, weight, material, and size. The pipe size affects the dimensions of each part of the flange, including the diameter, raised face, bore, hub, bolt, and bolt circle. Standards also exist for reducing long weld neck flange thickness, the length of the hub, and number of bolt holes. The standards help to make sure a proper fit in the pipe application.

Proper connection forging of carbon steel long weld neck flange adds strength to the pipes to compensate for the pressure. Our engineers monitor its manufacturing processes for quality assurance because of the important part its products play in safe operations and public safety.

Long welding neck flange Manufacturer elite supplies LWN flange , long weld neck flange class 150 , Long welding neck Flanges in forged steel, Stainless Steel, Carbon steel etc. Long welding neck flange is similar to a standard Welding Neck flanges, but the Neck is considerably longer than other flanges and it is often used as a nozzle for a barrel or column.
