Detailed Information

Prashaant Steel & Alloys is known as the pinnacle in the world of metal market for the best quality Long Weld Neck Flanges production in India. Prashaant Steel & Alloys’ large Long Weld Neck Flanges inventory allows us to supply our customers with the pipe fitting they need when they need them. Our inventory includes nickel, monel, inconel, hastelloy, stainless steel, copper, duplex stainless steel, and high nickel alloy flanges & pipe fittings. Long Weld Neck Flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for threaded pipe flanges, the standard height is 1/16″ for threaded pipe flanges under 400#. For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4″. Prashaant Steel & Alloys manufactures threaded pipe flanges in all steel material grades, including carbon threaded pipe flanges, stainless steel threaded pipe flanges and alloy threaded pipe flanges. Long Weld Neck Flange also has many different threaded pipe flanges in stock and ready to ship.

ANSI B 16.5 Duplex Steel Long Weld Neck flanges offer superior toughness and strength compared to ferritic stainless steels. It depends on the alarm. Duplex Long Weld Neck Flanges have applications in various industries like chemical, transportation, and storage.

The Long Welding Neck Flanges are often used for high-pressure applications. To order a Long Weld Neck flange, it is important to specify the pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe or Fitting, thus allowing undisturbed product flow and reduces turbulence and erosion at the joints too. Long Weld Neck Flange Joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. Long Weld Neck Flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.

Long Weld neck Flanges is required when an extended neck is required from the flange’s flat surface, which helps in accommodating the pipe more easily. It acts as a boring extension. It is used in chemical and petroleum industries and used in residential and commercial buildings. It performs well where there is level of stress and temperature fluctuates. Long Weld Neck Flanges have a hub that extends. The Long Weld Neck Flange Jis 10k type is often used as a nozzle for a barrel or a column. Long Weld Neck Flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.
