EN 1092-2 PN16 Long Weld Neck Flange Dimensions & MSS SP-44 2 Inch Long Weld Neck Flange Price List, 300# Long Weld Neck Flange manufacturer in India.
ASME B16.5 long weld neck flange dimensions are easy to recognize at the long tapered hub, because it goes progressively over to the wall thickness from a pipe or fitting.
The long tapered hub in the 300# long weld neck flange dimensions provides an important reinforcement for use in several applications involving extreme temperature conditions. For instance the stainless steel long weld neck flange is able to withstand high pressure, sub-zero and / or elevated temperatures. The smooth transition from long weld neck flange dimensions class 300 thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial. This holds true for the long weld neck flange 600#, especially under conditions of repeated bending, which could be caused by line expansion or other variable forces.
These carbon steel long weld neck flange have been bored to match the inside diameter of the mating pipe or fitting so there will be no restriction in the flow of product. This prevents turbulence at the joint of the stainless steel long weld neck flange and reduces erosion. The ASME B16.5 Long Weld Neck Flanges also provides excellent stress distribution through the tapered hub. In fact the carbon steel long weld neck flange can be easily radiographed for flaw detection.

ASME B 16.5 long weld neck flange has been limited to flanges and flanged fittings made from materials such as cast or forged materials. While blind flanges and certain reducing long weld neck flange can be manufactured from other materials such as cast, forged, or plate materials. Also included in this ANSI B16 5 long weld neck flange Standard are requirements and recommendations regarding the ASME B16.5 long weld neck flange dimensions for purposes such as bolting, flange gaskets, and flange joints.
This ASME B16.5 Long Weld Neck Flanges Standard is to be used by long weld neck flange manufacturers in combination with equipment’s that have been mentioned like the other volumes of the Standards in ASME B16 Series as well as with other ASME standards, like both the Boiler and Pressure Vessel Code as well as the B31 Piping Codes. The ASME B31.3 Piping Guide mentions :
In cases when the steel pipe is threaded and is used for steam applications above 250 psi or for water service above 100 psi with water temperature being above 220° F, the pipe has to be seamless and the thickness must be at least equal to schedule 80 of ASME B36.10.
What is ASME B16.5 Long Weld Neck Flanges?

long weld neck flange ASME B16.5 with pressure rating class designations i.e. class 150, class 300, class 400, class 600, class 900, and class long weld neck flange 1500# in a size range between NPS 1/2 up to NPS 24 long weld neck flange weight chart with pressure rating class designation class 2500 is available in sizes NPS 1/2 till NPS 12 in the long weld neck flange standard. The requirements of the rtj long weld neck flange have been given in both metric as well as the U.S. Customary units with diameter of bolts and long weld neck Flanges weight calculator bolt.
