Long Weld Neck Flanges Manufacturers in India

  • Long weld neck flange provide reinforcement in application requiring high pressure and during low and high pressure extremes. It also helps in low cycle fatigue caused by line expansion of other variable forces. Long weld neck flange bore is machined to match the ID of the pipe or fitting. This creates a smooth transition to and from the weld neck flange and prevents turbulence at the welding neck.

  • Stainless Steel Long Weld Neck Flanges Available Size ½’(15NB) to 48’ (1200NB)

  • Standards of Stainless Steel Long Weld Neck Flanges ANSI B16.5, ANSI B16.47 Series A & B, MSS SP44, ASA, API-605, AWWA, Custom

Stainless Steel Long Weld Neck Flanges Suppliers- Top Jindal, Steel Flanges in India!

  • Asiamet is a one of the largest manufacturer, supplier and exporter of long weld neck flanges in India. This kind of flange is chosen for unadorned service circumstances resultant from superior pressure high or sub zero temperatures.
  • Long weld neck flanges have an extended tapered hub and steady evolution of wideness in the area of the butt weld connection them to the pipe. This tapered hub offers significant strengthening to the flange and confrontation to dishing. They are having some great features like Fine construction, low maintenance, smooth finish, corrosion resistant, high strength, sturdy construction and more. Our long weld neck flanges can further be customized in terms of thicknesses, sizes and specifications as per the specific requirements of our clients. We offer these flanges at market leading prices.
  • The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub zero and or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness affected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.
  • Long weld necked flanges also known as LWN flanges are similar to the standard weld neck flanges but the neck is considerably longer. This type of flange is often used as a nozzle for a barrel or a column. They can be classified later as standard type, heavy gun type, variable body type and whole body type.
